History shows tougher environmental laws don’t have to hurt

The recent change in the political landscape has, in many cases, slowed the momentum on key environmental issues. As I have observed repeatedly during my 40-plus year career, environmental issues become less of a political priority when economic pressures increase. This potential backpedaling on environmental regulation is most concerning as global temperatures continue to rise, water bodies choke with nutrient pollution, wildlife habitats shrink, and the list of harmful persistent chemicals in the environment grows.

However, a 2016 study from the Organization for Economic Cooperation and Development (OECD) shows that countries that implement stringent environmental policies do not lose export competitiveness, when compared against those with more moderate regulations.

In fact, some emerging economies with strong manufacturing sectors, such as China and Brazil, have strengthened environmental laws, reduced oil consumption, and embraced renewable energy without denting their overall share in export markets.

The OECD study, Do Environmental Policies Affect Global Value Chains? found that tough environmental standards may drive firms to become more innovative, improving both their economic and environmental performance.

Ten years ago, I wrote about two major events in the early 1970s that affected the general public and the auto sector almost simultaneously. In an effort to reduce chronic smog events in many cities, amendments to the U.S. Clean Air Act mandated dramatically lower nitrogen oxides and sulfur dioxide emission levels in passenger vehicles.

To achieve this with the simple carbureted engine technology avail-

The author and his pride and joy.

able at the time, auto manufacturers had to lower average engine compression levels. In one model year (1972-73), they dropped from an average of 10:1 to 8:1. Drivers noticed an immediate impact, as this reduction in compression resulted in a substantial drop in horsepower.

As an example, several years ago I had to replace the worn-out engine in my 1970 Oldsmobile Delta 88 — a 350 cubic inch (5.7 litre) V8 that produced 200 net horsepower, laughable at today’s standards. The replacement engine, a 1973 model, produced only 165 net horsepower. As you can imagine, performance dropped dramatically for a car that weighed the same, yet lost 35 ponies.

Catalytic converters and other measures, such as exhaust gas recirculation, were introduced to meet even tougher emission standards, further cutting horsepower. Reduced engine performance also meant drivers suffered with low fuel economy as weaker engines needed to work harder. This pain was made even greater when the “Arab Oil Embargo” began in October 1973.

The embargo on oil shipments to the U.S. from most oil-producing Arab countries caused widespread fuel shortages and sent crude oil prices skyrocketing from $3 to

$12 per barrel by March 1974. In response, the U.S. government created the Corporate Average Fuel Economy (CAFE) standards in 1975, forcing auto manufacturers to improve the average fuel economy of cars and light trucks.

Facing stricter emissions limits and legislated fuel economy standards, the end of the big-car era seemed imminent. How could V8 carbureted engines with three-speed automatic transmissions survive? High performance was over, or so it seemed.

Fast forward to today, and nothing could be further from the truth. In response to tighter emission controls and CAFE standards, auto manufacturers developed new technologies, such as computerized fuel injection and engine management, variable valve timing, turbochargers, and more. Now, a four-litre engine that might have produced 90 horsepower in 1976 can generate over 400 horsepower, while burning less fuel.

Manufacturers also embraced advanced aerodynamic design and six- to 10-speed transmissions. The results were astounding. Today, a Ford F-150 pickup truck, which weighs over 2,500 kg, has similar fuel economy to the 1974 Ford Pinto, which weighed around 1,100 kg and was the smallest car Ford made at that time.

Automakers around the world continue to develop and introduce hybrid and all-electric vehicles at a rapid pace. Never before have consumers had so many powertrain options to consider, when purchasing a new vehicle.

It’s clear that stringent emissions and fuel economy regulations did not hurt auto manufacturers or drivers over the long run and are, in fact, vital to clean air and reduced carbon emissions. I truly believe the same also applies to many other broader environmental policies and look forward to the technologies and innovations that will be developed in the future.

What you need to know about the essential safety devices on aeration blowers

By Enrique Chapoy

In wastewater treatment plants, aeration blowers are a critical component for providing oxygen to support biological processes. Maintaining their optimal performance and longevity is paramount. That’s why safety devices are essential. They protect blowers from damage and ensure reliable operation.

These devices not only safeguard the equipment, they also help prevent costly downtime by indicating when preventative maintenance is required. Understanding the various safety devices, their functions, and maintenance requirements can help plant operators make informed decisions about operations, repairs, and upgrades.

PRESSURE RELIEF VALVE

The pressure relief valve (PRV) is an essential safety device. It is located at the discharge of the blower. This simple, yet effective, spring-loaded mechanism serves to protect the blower from excessive pressures using a calibrated spring. If the discharge pressure exceeds the PRV's calibrated pressure, it will overcome the spring tension and allow air to escape to atmosphere or exterior piping. However, the PRV is not a control valve, as it is meant for sudden pressure surges and spikes, not continuous operation at high pressures.

Pressure relief valves are adjustable, and different springs are available for setpoints depending upon operating conditions, motor limitations, or customers’ requests. Standard setpoints are 15.2 pounds per square inch gauge (PSIG) for “S” model blowers operating above 10 psi

and 10.9 psig for all machines operating under 10 psi, including all “L” model blowers.

Annually, operators should check that the valve is working by using a screwdriver to actuate the spring. If the spring is stiff or corroded, the valve will need to be serviced, or replaced. If an aeration blower becomes over-pressurized it can damage or even destroy the entire stage. If the pressure exceeds a calibrated setpoint, the PRV will protect the blower. It does not, however, protect against prolonged overloads or excessive discharge temperature.

DISCHARGE PRESSURE GAUGE

The discharge pressure gauge (or indicator) reads the pressure of the air at the discharge of the blower. It should be readily accessible and easy to read.

Operators should check the blower discharge pressure gauge regularly. If it reads above the maximum working pressure and the PRV has been actuated, steps must be taken to protect the blower and to troubleshoot the overpressure conditions.

The gauge should be inspected at the yearly scheduled maintenance intervals. It should be checked for signs of wear, cracks, corrosion, and tight connections.

If it is failing to register pressure or shows insufficient pressure for the speed it is running, or if it shows positive pressure when the blower is stopped, the gauge may need to be recalibrated or replaced.

FILTER MAINTENANCE INDICATOR

This safety device consists of a differential pressure gauge that detects the pressure of the air on both sides of the filter. As filters get dirty, the pressure differential increases, forcing the unit to work harder.

Clean filters are essential for efficiency. Dirty filters can choke the flow of air into the blower and cause overheating. This can cause premature wear to mechanical parts and cause a critical failure of the blower.

In essence, the filter maintenance indicator warns operators when the filter has become too dirty and needs to be replaced. When operators change the filters, they should inspect this gauge for signs of damage or wear. If the sensor, or its components, appear irregular or damaged, it should be replaced or recalibrated as well.

DISCHARGE CHECK VALVE

Like the PRV, the discharge check valve is a simple valve that serves an important purpose. In this case, it stops air (or water) in the lines from backflowing into the blower while it is off. If the valve fails and air flows back into the unit, it can cause the rotors to windmill in the reverse direction.

Under these conditions, the lack of lubrication can damage the rotating parts over time.

The full-bore check valve can be easily removed for inspection and maintenance without disconnecting the discharge piping. With its horizontal top-located steel shaft (except DN50), the check valve naturally closes by gravity at no-flow. Without any springs, the check valve will not chatter, even at low flow conditions.

DISCHARGE TEMPERATURE GAUGE

Similar to the discharge pressure gauge, the discharge temperature gauge measures the temperature of the air at the discharge. If the temperature goes

The discharge temperature gauge helps operators keep track of how hot the unit is getting and can be used to trigger shutdowns to prevent overheating.

above 140°C, it can lead to irreparable damage of the rotors, housing, and timing gears due to thermal expansion.

Excessive temperature will also cause premature wear of the bearings and seals. The discharge temperature gauge is connected to a probe installed at the discharge manifold.

During regular preventative maintenance, the gauge and probe should be checked for corrosion or damage. Operators can ensure the sensor is working by taking readings with the unit offline. The recorded temperature should closely match ambient temperature.

ADDITIONAL SAFETY MEASURES

While all these safety devices can and should be checked regularly, particularly during routine maintenance, there

is still the possibility of operator error. A gauge will not protect the equipment if it is not monitored.

Where regular inspections are not feasible, gauges and indicators can be supplemented with safety switches. These are an economical upgrade designed to automatically stop the equipment when a setpoint is surpassed.

A discharge temperature switch, for example, will be set to 140°C. The switch will stop blower operation above this temperature.

Operator error can be further reduced with the addition of a control system. These systems are designed to automate the blower’s operation and safety functions. The control system provides continuous parameter monitoring using pressure and temperature transmitters, as well as speed sensors.

Additional transmitters can be used to monitor oil temperature, intake temperature, system pressure, and even vibration levels. A control system will automatically stop the equipment when safety parameters are surpassed. Warnings and shutdowns are displayed on the control’s screen.

Additionally, a control system will keep track of running hours and inform operators when maintenance is required. If any safety device does fail, instructions on how to remove and replace them are provided in the blower’s user manual.

The removal and installation of new safety devices can be performed by any operator with basic mechanical skills. Every plant should have one spare of each in stock for each model of blower. Safety devices in aeration blowers are essential for ensuring reliable and efficient operation. By understanding the functions and maintenance requirements of these devices, operators can prevent costly downtime, protect equipment from damage, and enhance overall system performance.

Alberta ramps up flood-mapping to help guide municipalities

By ES&E Staff

Alberta has accelerated its flood-mapping program at a rapid pace, completing more maps in the last five years than in the previous three and a half decades combined.

Since 2020 alone, more than 1,850 kilometres of flood maps have been delivered, resulting in new or updated mapping for 70 municipalities and five First Nations. Alberta remains on track to surpass 3,000 kilometres of new and updated map ping by 2028, provincial officials announced.

It’s all part of an ongoing effort to help communities under stand where water will flow during major weather events and plan safer development in the future.

All rivers, streams and lakes in the province carry flood risk, and officials say the dramatic expansion of mapping gives farmers, homeowners and municipalities clearer guidance on where it is safe to build, how best to protect property and how to prepare for emergencies.

“We’ve seen firsthand that floods can destroy homes, dam age businesses and devastate communities, which is why we’re completing flood maps at a record pace to help communi ties plan better and keep Albertans safe,” announced Rebecca Schulz, Alberta Minister of Environment and Protected Areas, in a statement.

“Reliable flood information not only strengthens commu nity safety and resilience, but also supports fairer insurance rates for our municipalities,” said Dana Mackie, chief execu tive officer of Alberta Municipalities, in a statement.

The province has released five new flood studies covering key waterways across Alberta. The finalized studies were com pleted under the Flood Hazard Identification Program, with four jointly funded on a 50/50 basis with Natural Resources Canada.

The province expects nearly 600 kilometres of additional draft flood-mapping over the next two years for communities including Carbon, Chateh, Crowsnest Pass, Edson, Garden River, Grande Prairie, Kinuso, Lacombe, Lamont, Lethbridge, Manning, Millet, Paddle Prairie, Peers, Ponoka, Robb, Rycroft, Thorsby, Two Hills and Watino.

Flood maps now shape many local planning decisions. More than 80% of municipalities with provincial mapping reference it directly in land use bylaws, and officials say the information continues to be integral to emergency response planning and longterm community development. All flood maps for communities across Alberta are available for public viewing online.

Ontario will miss 2030 emissions target as climate plan stalls, audit finds

By ES&E Staff

Ontario remains in position to miss its legislated 2030 greenhouse gas emissions reduction target by a significant margin, according to a recent provincial audit that raises concerns about outdated plans, optimistic projections and stalled policy action.

Ontario committed in 2018 to cut emissions 30% below 2005 levels by 2030. While it has achieved a 22% reduction so far, driven largely by the phase-out of coal-fired electrical generation between 2005 and 2014, the review found that the government is projected to fall short of its goal by at least 3.5 megatonnes. The gap may be even wider, with evidence suggesting emissions will be higher than the Ministry of the Environment, Conservation and Parks (MECP) has forecast.

“In addition, despite legislated requirements to prepare a climate change plan and publicly report on progress, no finalized plan exists, and MECP has not released a new progress report since 2021,” Auditor General Shelley Spence stated in her review. The province also has no emissions reduction targets beyond 2030, she added.

In January 2025, MECP projected that Ontario would miss its 2030 target by 3.5 megatonnes, assuming full implementation of both provincial and federal climate initiatives. But the review found those assumptions overly optimistic, noting that projected emissions reductions are likely overstated in every major sector.

In response to the findings, MECP Minister Todd McCarthy told a press conference that his ministry will still endeavour to meet climate commitments related to the 2030 target. “But targets are not outcomes. We believe in achievable outcomes, not unrealistic objectives,” said McCarthy.

The audit states that the ministry’s modelling includes federal policies that no longer exist, such as the consumer carbon tax and electric vehicle rebates. It also does not account for provincial decisions that could increase emissions, including the permanent reduction of fuel taxes and removal of certain road tolls. These policies could encourage higher use of gasoline powered vehicles.

Projected reductions tied to industrial initiatives may not materialize as expected. For example, anticipated cuts from electrifying steel production are likely to be delayed. Ongoing trade disputes have also created economic uncertainty, potentially lowering industrial activity and emissions beyond what MECP anticipated.

The projection includes emissions reductions from the now-cancelled federal carbon tax and from energy efficiency standards that may weaken. Because Ontario’s standards are partly tied to those in the U.S., proposals to roll back efficiency requirements there could slow progress in Ontario. Mean-

Several provincial decisions could increase emissions, including the permanent reduction of fuel taxes and removal of certain road tolls, which may encourage higher use of gasoline powered vehicles.

while, provincial policies encouraging natural gas expansion may drive emissions higher, the review warns.

Despite a long-term upward trend in agricultural emissions, MECP assumes they will decline slightly, even though no mandatory programs exist to achieve reductions.

The waste sector forecast relies on Ontario meeting targets to cut and divert organic waste from landfills. But the review found “little to no progress” toward those commitments, including the province’s 2017 pledge to ban organics from landfills.

Future emissions from the electricity grid carry significant uncertainty. MECP assumes several major nuclear projects will be completed by 2030. Any delays could force greater reliance on natural gas generation, driving emissions higher. The projection also assumes rising electricity demand from industry and improvements in energy efficiency, both of which are uncertain given economic instability and proposed U.S. efficiency rollbacks.

Combined with outdated modelling and stalled reporting, the review warns that the province lacks a credible roadmap to guide future climate action.

Major wastewater project funding announced across Canada

By ES&E Staff

Two Ontario communities are moving forward with largescale wastewater infrastructure upgrades designed to support rapid growth, enable new housing, and modernize treatment capacity. New construction is now underway in Carleton Place and Brant County’s village of St. George, marking significant milestones for both municipalities.

The Town of Carleton Place, Ontario, has officially broken ground on construction of its largest ever infrastructure investment, a $133-million simultaneous expansion of both its water and wastewater treatment plants. Stantec, which has partnered with the town for years on long-term planning and detailed design, will provide construction-phase services,

including contract administration and engineering support, to help deliver the multi-year project.

Both plants are being significantly upgraded to address operational constraints and accommodate the community’s rapid population growth, projected to rise from 15,000 to 25,000 residents over the next 20 years. The expanded systems will also help Carleton Place meet Ontario’s housing supply goals by

enabling new development.

The wastewater treatment plant will see capacity rise from 7.9 to 10.6 million litres per day (MLD) on average, and from 22 to 42.5 MLD during peak hours. The expansion includes a conversion from conventional treatment to a membrane bioreactor (MBR) facility, strengthening reliability and effluent quality. The water treatment plant will increase its capacity from 12 to 19.5 MLD, with an expansion designed to fit seamlessly within its urban footprint while improving operator access.

ASCO Construction Ltd. has been awarded the construction contract, following a competitive tendering process. Work is expected to continue into early 2029.

In Brant County, construction of a $56-million expansion of the St. George Wastewater Treatment Plant began in January, supporting approximately 1,350 new homes approved for development over the coming decades. The project aligns with provincial priorities to increase housing supply and ensure infrastructure keeps pace with community growth.

Plant capacity will increase from 1,300 m³/day to 3,900 m³/day, guided by recommendations of the 2021 Class Environmental Assessment. The detailed design phase evaluated treatment technologies and selected MBR systems to meet stringent effluent requirements

and fit the plant’s constrained site.

Design work was completed in July 2025, with a draft Environmental Compliance Approval issued by the Ministry of the Environment, Conservation and Parks. ROMAG Contracting Ltd., a Mississauga-based environmental contractor, will deliver the project after being selected through a prequalification and tender process.

Construction is expected to begin in January 2026 and conclude by March 2028. A phasing plan for development in St. George is being prepared as part of Brant County’s official plan and is expected to come before council later this year or in early 2026.

QUEBEC

To extend the lifespan and improve the efficiency of the wastewater treatment plant in Saint-Hyacinthe, Quebec, the province and federal government have each increased their planned funding from $12.6 million to $24.9 million, bringing the total federal–provincial

investment to nearly $50 million.

The project includes modernization of the primary clarifier mechanics, roof renovations for the main building, new health and safety measures for staff, and upgraded automation systems to improve process control. These improvements are designed to ensure uninterrupted service and strengthen the plant’s long-term performance viewed as critical to residents of Saint-Hyacinthe and surrounding Maskoutaine communities.

Chantal Soucy, Member of the National Assembly for Saint-Hyacinthe, said the additional support was necessary to prevent cost overruns from falling directly on residents. “This additional assistance is excellent news for Saint-Hyacinthe. It is also a significant gain for the Yamaska River, as the planned upgrades will significantly reduce the amount of wastewater discharged, thereby improving its environmental condition,” Soucy said in a statement.

MANITOBA

Manitoba and the federal government are jointly investing $76.9 million in water and wastewater infrastructure to help rural municipalities upgrade essential systems needed to build more homes, support population growth, and keep life affordable.

Under the provincial stream of the Canada Housing Infrastructure Fund (CHIF), the funding supports long-term infrastructure priorities that directly enable increased housing supply. Projects receiving support include $22M for the RSR East Water and Wastewater Treatment Network, $22M for the RSR West (Brandon) Water and Wastewater Network, $22M for the Pembina Valley Water Co-op capital plan, $6.5M for the Boissevain Lagoon and $4.4M for the Morden sewer line to the town of Winkler.

Annacis Island WWTP outfall project earns provincial and national engineering honours

By ES&E Staff

The Annacis Island Wastewater Treatment Plant’s new outfall project received both provincial and national recognition in 2025, underscoring its technical achievement, collaborative delivery, and long-term benefits for more than one million residents in British Columbia’s Lower Mainland.

Last year, the project earned an Award of Merit in the Municipal and Civil Infrastructure category at the 2025 Association of Consulting Engineering Companies–British Columbia (ACEC-BC) Awards.

The honour recognized the collaborative execution and innovative design of the new outfall system.

More recently, the project was also named 2025 Canadian Project of the Year (Under $300M) by the Tunnelling Association of Canada, one of the country’s most prestigious awards for underground construction.

The national recognition highlights exceptional engineering skill, innovation, and a forward-thinking approach to resilience and environmental protection. The overall budget for the new outfall system is approximately $356 million.

The Annacis Island plant treats wastewater from a million residents across 14 municipalities. Its original 1970s-era outfall pipe needed to be replaced as it was too small, in poor condition, and not up to modern seismic standards. The new tunnel, completed in August 2025, provides increased capacity, enhanced durability, and seismic resilience, while improving effluent dilution in the Fraser River. Key features of the project include:

• Significantly boosting discharge capacity to ensure long-term service reliability.

• Two 4.2-metre-diameter conveyance tunnels constructed below liquefaction-prone zones to enhance performance

The new outfall system addresses future sea level rise and significantly improves the wastewater treatment plant’s resilience, ensuring reliable operation after a seismic event and adaptability to future environmental changes.

during seismic events.

• Use of a 5-metre-diameter slurry tunnel boring machine to achieve precise tunnelling and installation of precast concrete linings.

• In-river diffuser manifolds designed to promote effective effluent dispersion into the Fraser River, while minimizing ecological impacts.

• An outfall shaft engineered to accommodate a future pump station, address-

ing sea-level rise and long-term discharge needs.

Hatch served as construction manager for the project, working alongside CDM Smith Canada as Owner’s Engineer, in partnership with Metro Vancouver and Pomerleau Bessac General Partnership.

Real-time hydraulic model integration helps close the gap on digital twin capabilities for stormwater management

By Greg Johnston

Municipal stormwater departments invest significantly in hydraulic models, such as Storm Water Management Mode (SWMM), InfoWorks, or MIKE models. These represent years of engineering effort calibrated against monitoring data, validated through design storms, and refined through successive planning studies. Yet for most utilities, these models sit dormant between projects, producing static reports that become outdated the moment they’re printed.

The problem isn’t the models themselves. It’s how we use them. When a major storm approaches, operators check rain gauges and sensor levels, not model predictions. When green infrastructure

is installed across a watershed, years pass before anyone re-runs the model to assess its impact. When a sensor fouls or drifts, it may go unnoticed until the next calibration cycle, if there is one.

What if these models could run continuously, automatically comparing predictions against live sensor data? What if the same interface operators use for monitoring could also show them what the

model expects to happen and alert them when reality diverges from prediction?

This is no longer theoretical. A recent project in the Metro Vancouver region demonstrates that integrating hydraulic models with real-time monitoring platforms delivers practical operational benefits today, using tools accessible to utilities of any size.

Maintenance In Place (MIP®)

FROM PLANNING TOOL TO OPERATIONAL ASSET

The Metro Vancouver project began with straightforward questions from municipal clients. The municipality had been implementing green infrastructure across a fully urbanized watershed for nearly two decades. Rain gardens, green roofs, and impervious area disconnections had been installed through both private redevelopment and public capital programs. But how could they measure whether these investments were actually working?

They also wanted to know whether a real-time model could provide alarms at ungauged locations, particularly at critical culvert crossings where capacity exceedances could cause flooding. Could the model detect when flow monitoring sensors fouled or drifted? And could it provide flow forecasts based on weather predictions?

Kerr Wood Leidal Associates Ltd. (KWL), a Vancouver-based consulting engineering firm, had maintained the

watershed’s SWMM model since the 1990s. The model was well-calibrated to historical monitoring data and had been used for numerous planning studies. The question was whether it could be brought online to run continuously.

The integration was accomplished through infinitii face pro, a Python scripting engine that extends the functionality of the infinitii flowworks monitoring platform. The technical approach was straightforward: Python scripts download real-time and forecasted climate data from online sources, execute the SWMM model, and push the results back into flowworks, where they appear alongside live sensor data.

The entire integration took weeks rather than months. No custom software development was required — just configuration of existing tools and adaptation of the client’s calibrated model.

OPERATIONAL BENEFITS IN PRACTICE

Once running, the integrated system

delivered immediate operational value. Flood forecasting became possible by feeding seven-day weather forecasts into the model. Operators could see predicted flows at any location in the drainage network, not just where sensors were installed. For a watershed with steep terrain and flashy hydrology, this advance warning proved particularly valuable.

Alarms at ungauged locations addressed a critical gap. The watershed had flow monitoring at its outlet, but several upstream culvert crossings had known capacity constraints. The model now provides continuous flow estimates at these locations, triggering alerts when predicted flows approach or exceed design capacity. This capability would traditionally require installing additional monitoring equipment, with associated capital and maintenance costs.

Sensor validation emerged as an unexpected operational benefit. When model predictions consistently diverge from sensor readings under conditions continued overleaf…

where they should agree, it often indicates sensor fouling, drift, or malfunction. Operations staff now have an automated cross-check that flags potential sensor issues for investigation, reducing the risk of decisions based on faulty data.

All of these capabilities appear within the same infinitii flowworks interface that staff already use for routine monitoring. There was no new system to learn, no additional login to manage. The model outputs simply became another data source alongside the existing sensors.

MEASURING GREEN INFRASTRUCTURE EFFECTIVENESS

The most compelling outcome of this project was not planned as an operational feature. It emerged from the decision to keep the model calibrated to historical conditions, rather than updating it to reflect current watershed characteristics.

KWL had calibrated the model to flow monitoring data from 2010, before most of the green infrastructure had been implemented. When the model was brought online and began running against current sensor data, a clear pattern emerged.

During winter storms, when soils are saturated and green infrastructure provides minimal benefit, the model predictions matched observed flows closely. The calibration remained valid.

During spring and summer storms, however, the model consistently over-predicted flows. The same model parameters that accurately predicted winter runoff were producing estimates higher than what sensors recorded during drier conditions. This divergence was not a calibration failure. It was evidence that the green infrastructure was working.

When soils are dry, rain gardens and disconnected impervious areas absorb and infiltrate rainfall that would previously have run off directly to the storm system. The model, still representing the historical watershed, predicted what flows would have been without these improvements. The difference between prediction and observation quantified the runoff reduction achieved.

This approach, using calibration drift as a measurement tool, provides something that green infrastructure programs often struggle to demonstrate, which is empirical, continuous evidence of per-

formance. Rather than relying solely on design calculations or periodic studies, the municipality can now observe the cumulative effect of their investments in near real-time.

The engineering team has since begun updating the model calibration to match current conditions, systematically increasing impervious disconnection parameters until predictions align with observations. Early results suggest the effective impervious area has dropped from approximately 50% to mid-20%, a substantial reduction attributable to two decades of green infrastructure implementation.

CLOSING THE GAP ON EXPENSIVE DIGITAL TWIN CAPABILITY

Projects like this would traditionally require significant custom development, specialized real-time modelling software, or expensive digital twin platforms marketed primarily to large utilities. The tools used here — an existing SWMM model, a standard monitoring platform, and a Python scripting engine — represent a fraction of that cost and complexity.

This accessibility matters. Most Canadian municipalities are not large enough to justify enterprise-scale digital twin investments. But they do have hydraulic models developed through master planning studies. They do have monitoring data flowing into operational platforms. The gap between these assets is narrower than many realize.

The Python scripting capability within infinitii face pro proved essential to this project’s success. It allowed the engineering team to write custom code handling data retrieval, model execution, and results processing — without requiring

changes to the core monitoring platform. Similar integrations have since been completed using other modelling tools, including UBC’s Raven watershed model and the Soil and Water Assessment Tool (SWAT) platform.

IMPLICATIONS FOR PRACTICE

This project suggests a shift in how utilities might think about their hydraulic models. Rather than assets that produce periodic reports, models become continuous operational tools that generate value daily.

The benefits extend beyond the specific applications demonstrated here. A model running continuously against live data will reveal calibration issues faster than periodic studies. It will identify locations where actual system behaviour differs from design assumptions. It will provide a framework for evaluating the performance of any intervention, whether green infrastructure, pipe rehabilitation, or operational changes.

Perhaps most importantly, it makes the model’s predictions visible and testable. When operators can see model outputs alongside sensor data every day, they develop intuition about where the model performs well and where it needs refinement. The model becomes a living tool rather than a static artifact.

For utilities considering this approach, the technical barriers are lower than they may appear. The critical requirements are a calibrated model, a monitoring platform capable of hosting custom scripts, and engineering expertise to configure and validate the integration. The project described above required no proprietary real-time modelling software, no specialized hardware, and no multi-year implementation timeline.

The question is no longer whether hydraulic models can be integrated with real-time monitoring. It’s whether utilities can afford not to adopt them.

Poll finds Canadians value freshwater but feel uninformed, highlighting national knowledge gap

By ES&E Staff

Arecent national survey suggests that while Canadians increasingly recognize freshwater as the country’s most vital natural resource, most do not feel well informed about the issues affecting it. The findings, released by the charity AquaAction, are based on the polling of nearly 1,200 Canadians and point to a widening divide between public concern, understanding, and urgency when it comes to freshwater protection.

Conducted through Cint market research between August and September 2025, the poll updates questions first posed in a 2021 Environment and Climate Change Canada (ECCC) survey on freshwater perceptions. The new research also includes responses from Michigan residents, reflecting AquaAction’s expanded cross-border work, following the opening of its U.S. office.

More than half of Canadians surveyed (52.6%) identified freshwater as the nation’s most important natural resource, ranking it well ahead of forests and other assets. Despite this, only one-quarter of respondents described themselves as “very informed” on freshwater issues. More than one-third said they felt poorly informed, a gap researchers say limits people’s ability to understand threats, evaluate policies, and take meaningful action.

“This new survey reveals that people deeply value freshwater, but they’re not seeing the excellence they expect,” said Soula Chronopoulos, AquaAction president. “By making education a required part of water programs, framing policies through health outcomes, and accelerating the adoption of proven innovation, we can move toward stronger, more accountable freshwater protection. Residents on both sides of the border are telling us exactly what they want in this study, and now it is time to deliver it.”

The poll results also indicate that freshwater has become even more important to Canadians since the 2021 baseline survey. AquaAction attributes the rising awareness to climate-related droughts and floods, contamination incidents, and increased national attention on long-standing Indigenous water crises.

Survey participants ranked clean water for future generations and human health as their highest priorities. Economic and aesthetic considerations were cited far less frequently. While 70.8% of Canadians said they were concerned about water quality, only 32.4% expressed strong concern. Just 15.8% rated existing protections as “excellent,” suggesting low levels of urgency despite broad recognition of risk.

Researchers described the findings as a “concern–knowledge–urgency gap.” Canadians value freshwater, but many lack the understanding needed to recognize threats or engage in

solutions. Twelve percent of respondents reported no personal connection to freshwater at all, underscoring what AquaAction calls the resource’s “invisibility” in daily life.

The survey also revealed that language plays a significant role in shaping public engagement. Terms such as “water security” and “water crisis” conveyed urgency and were widely understood, while “watershed” remained unfamiliar to many Canadians. AquaAction says vocabulary gaps hinder public participation in conservation and policy discussions.

The organization presented the findings during a national webinar attended by researchers, community leaders, and water-sector experts. It says the results will help shape a national water-literacy campaign being developed in partnership with Canadian educational institutions and with support from the federal government.

The 2025 survey builds on ECCC’s 2021 Value and State of Freshwater and Appropriate Responses to Freshwater Issues research, which drew on responses from 2,001 Canadians. AquaAction’s updated study replicates several of the original questions to measure trends over time and incorporates open-ended responses that map how different words influence public understanding of water issues. A full white paper detailing the survey methodology and findings is available through AquaAction.

Modular engineering approach used for Sachs Harbour, N.W.T. water treatment plant

By Kagan Kilicaslan

For leaders and decision-makers responsible for critical infrastructure in remote locations, such projects require robust and reliable water systems, with proven performance. Recognizing the harsh environmental conditions, logistical constraints and limited construction season, there is little margin for error.

The community of Sachs Harbour, Northwest Territories, one of Canada’s most northern settlements at 71° 59' N,

faced this stark reality as climate change degraded its primary surface water source, introducing unprecedented variability in turbidity and organic content.

BI Pure Water was tasked with designing and manufacturing a modular potable water treatment plant, and arranging for transport to the site, installation and commissioning. The Sachs Harbour project addressed two critical engineering challenges by demonstrating a complete Engineer-Procure-Construct (EPC) methodology. From precision design and factory fabrication to remote operational intelligence, this approach systematically transforms project risk into long-term operational reliability.

Firstly, the raw water quality from the surface source had become degraded, with recorded turbidity levels fluctuating

between 1–8 NTU and dissolved organic carbon (DOC) as high as 10.4 mg/L. This variability demanded a treatment process robust enough to handle significant swings in feed water characteristics.

Secondly, was the logistical paradox of deploying a complex, sensitive electrical and mechanical facility to a location with an effective construction season measured in weeks. The site is accessible only by air and a single, annual sealift, creating a narrow, non-negotiable window for delivery.

Any viable solution had to be shipped complete, survive a long and arduous journey, and be operational with minimal on-site work, all while being engineered to protect the fragile permafrost foundation upon which it would sit. This was not a standard water infrastructure improvement project. Rather, it was a precision logistical and engineering mission where every component and sequence required meticulous advance planning.

PRECISION ENGINEERING MEETS MODULAR INNOVATION

The entire water treatment plant was engineered as two primary CSA A660/ A277-certified modular buildings. Factory-fabricated in two sections and engineered to exceed the Good Building Practices Guideline, the modular buildings offer resistance to environmental conditions and a 30-year design horizon. They were built fully piped, wired, and tested in our climate-controlled facility in Surrey, B.C.

This approach allowed us to lock in the project schedule, control quality and costs, and perform comprehensive Factory Acceptance Testing (FAT) far from the blizzards and freezing temperatures of the Arctic.

Each module was designed as a self-contained enclosure of functionality, weighing between 10,000 and 15,000 kg, and housing not only the complete treatment process, but also fully integrated support systems, including electrical distribution, a 50 kVA standby generator, HVAC, and control networks. The design incorporated a 100-amp, 600volt electrical service entrance and two dedicated fuel tanks for the furnace and generator, ensuring more than 10 hours

of runtime for essential services.

Upon arrival, via the critical annual sealift, the plant modules were rapidly interconnected on-site. A foundational aspect of the design was the elevation of the entire structure on beams, to minimize thermal exchange and preserve the underlying permafrost from degradation, thereby ensuring long-term structural integrity.

This modular strategy turned a potential multi-season, high-risk field construction project into a swift, predictable, and decisive deployment.

CORE TECHNOLOGY BUILT FOR RELIABILITY AND REMOTE CONTROL

At the heart of the plant is a multi-barrier treatment process engineered specifically for maximum reliability, given the challenging source water. The process train begins with raw water pumped at a design flow of 121 litres per minute through 100-micron basket strainers for solids removal.

This is followed by precise chemical conditioning, injecting coagulant (either liquid alum or PAC) and caustic (sodium hydroxide) for the oxidation and precipitation of dissolved metals like iron and manganese, with in-line static mixers ensuring optimal dispersion.

Conditioned water then enters a flocculation tank, with a designed hydraulic retention time of three minutes. Mixing energy is supplied by a dedicated aeration system, promoting the formation of settleable floc.

The core treatment technology consists of a pressurized ultrafiltration system utilizing advanced, high-recovery pressurized ultrafiltration (UF) membranes with 0.02-micron PES membranes. This system provides an absolute physical barrier, achieving a proven 3-log removal of pathogenic protozoa like Cryptosporidium and Giardia.

Final disinfection is achieved with chlorine, providing the required 4-log virus inactivation. The 20 m3 treated water storage tank was sized based on rigorous CT calculations (contact time x concentration) to ensure regulatory disinfection levels are met, even with the design raw water temperature of 0.5° C, and the poor baffling condition (baffling factor of 0.3) within the tank.

This entire process is designed for compliance with Canadian drinking water standards, meeting requirements for ≤ 0.1 NTU turbidity, and a chlorine residual of at least 0.5 – 1 mg/L entering the distribution system.

This treatment system is housed within a building designed for the Arctic environment. The CSA certified modular building, features a heavily insulated envelope achieving RSI 8.6, an oil-fired furnace, and a backup generator for complete operational independence.

Crucially, a sophisticated remote monitoring and control SCADA system, built on a PLC control system provides advanced diagnostics, trending analysis, and the ability for remote troubleshooting and support. This system allows for real-time performance tracking of key parameters, including transmembrane pressure (TMP), turbidity, pH, and residual chlorine. It also enables remote troubleshooting, and facilitates

predictive maintenance from thousands of kilometres away. This capability drastically reduces the lifecycle cost and operational risk associated with emergency site visits, ensuring operational continuity is guaranteed and technical support is immediate. Furthermore, the WTP is designed with an automatic fire flow bypass that delivers 1,000 L/min of chlorinated raw water directly to a fire truck, ensuring emergency readiness and eliminating the need for additional fire water storage.

A DEFINITIVE SUCCESS IN SUSTAINABLE WATER PROVISION

The success of the Sachs Harbour Water Treatment Plant is measured not just in its successful design and delivery, but in the enduring value and resilience it creates for the community. The project was delivered on schedule, overcoming immense logistical hurdles to provide a dependable, long-term water source.

The plant is capable of producing water that consistently exceeds the latest Guidelines for Canadian Drinking Water Quality, and the complete inactivation of target pathogens. Its design integrates a comprehensive, pre-defined 10-year maintenance schedule, providing the community with operational clarity and long-term cost predictability.

The plant’s design also addresses waste streams, incorporating a 1,500-litre neutralization tank for chemical cleaning waste and an overland discharge for filter backwash, ensuring environmental compliance.

From the integrated and redundant truck-fill system capable of 1,000 litres per minute, to the fire flow bypass that provides chlorinated raw water for emergency response, every detail was engineered for sustainability, autonomy, and community safety.

Preparing piloted control valves for winter

By Mark Gimson

As temperatures drop, water system operators face freezing conditions that can impair or disable piloted control valves. These play a critical role in regulating pressures, flows, and levels throughout potable water networks. Thereforeproper winter preparation is essential to ensuring uninterrupted operation.

Piloted control valves contain small-diameter tubing, pilot controls, and internal passageways that are vulnerable to freezing. When water expands within these confined spaces, the resulting damage can compromise valve operation and lead to significant system disruption. Taking proactive steps before winter reduces the likelihood of freeze-related failures and protects system performance.

These valves rely on stable hydraulic signals transmitted through tubing, pilot assemblies, and internal components. Even minor freeze events can block these pathways, alter setpoints, or fully immobilize valve operation. While many valves are constructed from durable materials, such as ductile iron and stainless steel, precision components within the pilot system remain susceptible to freeze damage if not adequately protected.

When pilot lines freeze, the valve can no longer modulate or control system behavior, which creates operational risks, pressure fluctuations, and potentially costly service interruptions.

Different valve functions present different winter vulnerabilities. Common installations include pressure reducing valves, which are highly dependent on clear, unrestricted pilot lines; among the most susceptible to freeze-related mal-

function. Pressure relief valves are important for system safety. A frozen pilot system can prevent proper opening during an overpressure event. Altitude valves are frequently installed in elevated or exposed locations, increasing exposure to extreme temperatures and wind chill.

Understanding valve inventory, site conditions, and historical cold-weather challenges will help operators prioritize winterization efforts. Before temperatures drop, each valve station should be assessed for vulnerabilities. Inspect for cracked, aging, or stressed pilot tubing, leaking fittings or joints, corrosion or deterioration on valve bodies and external components and evidence of previous freeze damage.

Any compromised tubing or fittings that allow moisture intrusion can become problematic once freezing conditions begin.

Valve vaults, pits, and chambers often accumulate water from storm infiltration or groundwater intrusion. If left unaddressed, these confined spaces can freeze, encasing pilot lines and valves in ice. Key actions include confirming all vault drains are clear and functional, ensuring sump pumps are operational and verifying that heaters or insulation systems, where installed, are in working condition. A dry, well-maintained vault

is one of the most important defenses against freeze damage.

Pilot systems regulate valve performance and are particularly vulnerable to freezing because of their small water volume. Recommended practices include insulating exposed pilot lines, installing heat trace where feasible, inspecting and cleaning inlet strainers to ensure unrestricted pilot flow, and confirming tubing routing minimizes exposure to cold surfaces. Because frozen water expands, even robust pilot components can be damaged if not properly shielded from extreme temperatures.

Operational testing prior to winter is essential. This should include cycling valves fully open and closed, confirming that pilots respond accurately to pressure changes, inspecting gauges to ensure they operate correctly and are not sticking, and checking responsiveness across the full control range. A valve that operates smoothly before freezing temperatures is far less likely to experience mid-winter performance issues.

Winter often exposes weak spots in elastomers, seals, O-rings, and pilot components. Keeping an inventory of essential spare parts enables timely repairs, even when supply chains are strained by weather. Recommended spares include diaphragms and elastomers, tubing and fittings, pilot component kits and O-rings and sealing materials. A well-prepared stock ensures minimal downtime during winter events.

Accurate documentation is a critical part of long-term winter readiness. Records should include valves inspected and exercised, components repaired or replaced, condition of vaults, drains, and heaters and implementation of pilot protection measures. Comprehensive documentation supports operational continuity, regulatory compliance, and informed decision-making for future maintenance cycles.

When valves are properly winterized, they perform their function quietly and reliably, even in the harshest conditions.

Fibreglass water storage tanks enable code-compliant fire protection for rural Ontario poultry facility

By Étienne Racine

When Amir Quality Meats began construction on a modern poultry processing facility in rural Ontario, the project team encountered an unexpected challenge, as the site had no municipal water supply.

That absence created a significant obstacle. To meet Ontario Building Code requirements and National Fire Protection Association (NFPA) standards, both of which mandate reliable water storage and delivery for building-wide sprinklers, the facility required a fully engineered solution developed

from the ground up. The system also had to operate reliably year-round in northern Ontario’s demanding climate.

The project team included Coldbox as general contractor, Superior Sprinklers Co. Ltd. as fire protection specialists, and Granby Composites, who were responsible for fabricating the water storage tanks and wet well (pumping station). From initial design to final installation, the project spanned three years.

The fire protection system required three fibreglass storage tanks with a combined capacity of 400,000 litres. These tanks were connected via underground piping to a wet well housing a vertical turbine fire pump. The pump had to maintain pressure throughout the facility’s sprinkler system while meeting NFPA 13, 20, and 24 standards. An on-site dry hydrant provided the local fire department with access to the water supply.

While the design appeared straightforward on paper, site conditions were anything but. Wet ground conditions required extensive dewatering before installation could begin. Northern Ontario winters limited installation time frames, and multiple contractors had to coordinate their work precisely to avoid delays.

In February 2025, Granby Composites delivered the wet well, which is the central component of the fire protection system, during challenging winter conditions, with dewatering still underway. More stable ground conditions in early summer allowed for the phased delivery and installation of the three 134,000-litre fibreglass tanks. Each tank was delivered and installed sequentially, before the next phase began.

This approach required continuous coordination between the tank supplier and on-site contractors. Delivery schedules shifted,

site conditions evolved, and engineering details occasionally needed clarification on short notice.

Granby Composites also provided on-site technical guidance during critical installation phases. This helped resolve issues quickly and prevented schedule disruptions.

The project extended beyond the installation of storage tanks. The three fibreglass tanks had to integrate seamlessly with the wet well, which in turn housed a fire pump capable of delivering sufficient pressure to every sprinkler head in the facility. Achieving this integration required close coordination among the general contractor, fire protection specialists, pump installers, and piping contractors.

By the fall of 2025, installation was complete. The system met all fire protection requirements, including NFPA 13 standards for sprinkler installation, NFPA 20 for the fire pump, and NFPA 24 for water storage tanks and underground mains. Full Ontario Building Code compliance was verified.

The installation of the three fibreglass water tanks and wet well remained within the project’s cost projections. Over a three-year design and construction timeline, with a total project cost

exceeding $1 million, meeting budget targets was a notable achievement.

For rural facilities facing similar challenges of remote locations without municipal water, difficult site conditions, and stringent fire code requirements, this project demonstrates how engineered solutions, responsive supplier support, and coordinated project man-

agement can deliver compliant, reliable fire protection systems on schedule and on budget.

Retrofitting the Wabaseemoong Independent Nations’ WWTP from a RBC to a MBBR

For remote and Indigenous communities in cold areas across Canada, providing reliable, effective sanitation infrastructure can be challenging, as they face severe environmental conditions, logistical complexities and sustainability constraints. The recent upgrade to the wastewater treatment plant (WWTP) serving the Wabaseemoong Independent Nations (WIN) in northwestern Ontario is one example of innovative engineering and collaborative problem-solving.

The Wabaseemoong Independent Nations, a community with a population

of approximately 1,200 people, faced a pressing environmental and health crisis in late 2021. The two parallel rotating biological contractor (RBC) units, which formed the core of their wastewater treatment process had been in operation since 2001. However, they experienced catastrophic failures with shaft and bearing breakage, which rendered the plant non-compliant and inoperable.

As such, the community urgently needed a solution to restore vital sanitary sewer services. However, replacing the failed equipment with a like-for-like RBC system presented an insurmountable logistical barrier. The building where the reactors were housed had been constructed around them, after initial installation.

This meant installing new RBC internals would be prohibitively expensive, requiring the partial demolition of the existing building. Given this limitation, the solution would need to utilize the existing tank structures, while also

achieving robust cold-climate treatment capabilities.

The operational minimum temperature for a mechanical plant in this region is approximately 5°C, a demanding standard that traditional systems often struggle to meet. In search of an innovative solution, WIN engaged with JR Cousin Consultants Ltd. (JRCC), out of Winnipeg, who in turn connected with Nexom, an Axius Water company. Given the complexity of the cold-weather treatment solution, the team decided to implement the Nexom BioPorts™ moving bed biofilm reactor (MBBR) for BOD and ammonia treatment in the existing RBC tanks.

This system utilizes free-floating media, which could be easily installed into the existing tanks, without the need for major structural modifications to the building. This immediately resolved the primary logistical challenge of replacing the existing RBC equipment.

However, the existing tanks presented a new set of engineering challenges, as they were not ideally configured for typical conventional MBBR systems. Standard MBBR designs often rely on water depths of up to 3.05 to 3.66 metres to ensure uniform distribution of aeration equipment and proper mixing of the floating media.

Wabaseemoong WWTP tanks featured typical RBC construction of sloped sidewalls and a shallow water depth of 1.2 metres. This configuration threatened the effectiveness of the aeration process crucial for biological treatment to occur. However, JRCC and Nexom engineers were able to customize the BioPorts system to fit the unique geometry of the existing infrastructure.

Twelve EDI CoarsAir™ MaxAir stainless steel diffusers were installed in each tank of the MBBR system, for a total of 24 diffusers, providing energy efficient aeration that would not require membrane

replacement. The innovative design of the BioPorts system, tailored for the shallow tanks, proved to be effective at dispersing the media and transferring sufficient oxygen despite the constraints.

The economic benefits of the MBBR approach were also significant. This retrofit solution was estimated to be approximately 30% cheaper than a typical RBC replacement, offering substantial cost savings for the community, while providing a modern, efficient upgrade. Various mechanical and electrical upgrades and repairs were also made within the plant, as part of the overall project.

IMPLEMENTATION

The collaboration between the Wabaseemoong Independent Nations community, JRCC, Nexom, and the contractor (Penn-co Construction) resulted in a remarkably tight, yet successful, execution timeline. The contract was awarded in early 2023, and the new MBBR treatment equipment was commissioned in November of the same year.

This rapid turnaround, which typically takes a couple of years for a project of this nature, underscores the efficiency of the chosen solution and the dedication of all parties involved.

The performance of the upgraded treatment equipment has been exemplary since it began full operation. The system consistently exceeds the stringent effluent requirements set forth by regulatory bodies, demonstrating the efficacy of the customized MBBR solution even in the non-ideal tank conditions. It is user friendly and requires minimal maintenance. Plant operators are able to complete regular servicing of the blowers, with the assistance of Nexom technicians.

The design parameters for the plant included a biological process flow rate of 876 cubic metres per day (m³/d) at 5°C, with a summer or high temperature (with less concentrated influent) flow rate of 1,442 m³/d. The required effluent quality standards were rigorous: total suspended solids (TSS) below 25 mg/L, biochemical oxygen demand (BOD) below 25 mg/L, and critical ammonia-nitrogen (NH3N) levels below 1 mg/L in the summer and 5 mg/L in the winter.

The plant has reliably met and surpassed these targets, even at the low temperatures prevalent in northwestern Ontario.

A BLUEPRINT FOR FUTURE INFRASTRUCTURE

The wastewater treatment plant upgrade at Wabaseemoong Independent Nations represents more than just a successful engineering project. It is a practical blueprint for sustainable infrastructure development in challenging environments. This successful retrofit of a failed RBC system with a cutting-edge MBBR system highlights how modern technology can overcome significant infrastructure hurdles, even under

urgent deadlines and within the constraints of a harsh cold-weather climate. With this MBBR installation there was full integration into their existing structure, giving the community intensified treatment within a small footprint, with low civil and land acquisition costs. Their treatment system meets all existing limits, while being both simple to operate and reliable well into the future.

Overcoming the challenges of environmental and chemical exposure on chemical dosing pumps

By Patrick Murphy

Chemical dosing/metering pumps are often exposed to harsh environmental conditions, such as extreme heat and UV light, cold, rain, wind, dirt and sand. When they are exposed to such harsh conditions and then viscous and/or corrosive chemicals are added to the mix, how can we expect them to continue delivering accurate and reliable chemical dosing?

For a chemical metering pump to perform successfully, materials used for components such as pump head tubes, O-ring seals, and diaphragms must be rated appropriately for the temperatures and chemicals they will encounter. For example, some elastomers may become brittle and eventually fail in the cold, which can lead to chemical leaks, unplanned downtime, and may potentially create a chemical hazard for employees.

Chemical compatibility is critical when specifying pump tubes or diaphragms. Those constructed of polyvinylidene fluoride (PVDF) are often preferred over polyvinyl chloride (PVC), and other fluoropolymers, due to PVDF’s superior resistance to high temperatures, pressure, and corrosive agents.

Although it may initially be more costly, PVDF eliminates many concerns regarding chemical compatibility and temperature range.

Some manufacturers may also offer optional, specialized pump tubes designed for specific chemical challenges.

COMBATING VOLATILITY AND VISCOSITY

Extreme temperatures don’t just impact the pump and its components. Volatile

Smart chemical metering pumps should not be limited by conditions such as harsh chemicals or extreme environments.

chemicals, such as chlorine, can evaporate or off-gas when exposed to heat, which may lead to operational problems such as vapour locking. This is not a concern with peristaltic pumps, which are not subject to vapour lock.

With regard to diaphragm pumps, which can experience vapour locking, there have been advances in “smart” diaphragm pump technology to help avoid this problem.

One example is dual diaphragm pumps outfitted with cutting-edge Hyper Drive Technology. These pumps operate so that when one diaphragm is in the suction phase, the other is in the discharge phase. This results in a near-continuous, smooth chemical feed profile, whichmitigates the issue of vapour lock. It may also be possible to help prevent vapour lock by using specialized external valves that allow gases to escape.

Another issue that often impacts pumping action is cold environments which can affect viscosity, causing fluids to thicken or form slurries. This makes them far

more difficult to pump. When pumping viscous fluids, chemical metering pumps experience increased hydraulic resistance, which requires higher motor torque. As a result, the motor draws additional current, and the drive and power supply must be properly sized to support this demand. If the pump, motor, or power supply are undersized, the pump is at increased risk of underperforming, stalling, faulting, or shutting down due to overcurrent or torque limit conditions.

DESIGNING FOR PROTECTION FROM ENVIRONMENTAL ELEMENTS

When selecting a chemical metering pump, operating temperature isn’t the only environmental condition to be considered. It’s important to check the pump’s performance ratings as well.

High-performance pumps often carry ratings such as National Electrical Manufacturers Association (NEMA) 4X and International Electrotechnical Commission’s IP 66, which certify that the pumps have been tested to confirm a high

degree of protection against the ingress of water, rain, dust, and sand. These standards verify that motors and electronics are shielded from these elements, which can cause damage over time.

This also ensures protection against chemical vapours or liquids getting into the pump housing and possibly leading to pump failure. In addition to protection from elemental hazards, the pump design must also account for thermal and light management.

For example, pumps should be engineered with internal cooling mechanisms to prevent overheating and to trigger automatic shutdown in overheating situations. Another consideration is that, when operated in direct sunlight, components like touchscreens can become vulnerable to UV damage. Smart controls should be shielded from UV light in order to maintain screen functionality and prevent material degradation.

A RELIABILITY AND CERTIFICATION

Beyond rugged design, manufactur-

ers validate metering pump performance through stringent third-party testing, to prove claims of durability and safety. Engineering firms often look for certifications, including listings from agencies such as Underwriters Laboratories (UL), Canadian Standards Association (CSA), European Conformity (CE), and National Sanitation Foundation (NSF). These listings verify safety, electrical standards, temperature performance, and chemical compatibility.

Flammability ratings are often over-

looked. There are some pump manufacturers whose pump enclosures are constructed of fire-retardant materials designed to stop fire. Ratings such as UL 94 V-0 ensure that any internal fire is contained within the pump, mitigating the risk of flames spreading throughout the facility.

EVOLVING PUMP CAPABILITIES AND ROI

While peristaltic pumps were historically associated with low-pressure applications or laboratory use, the underlying technology has advanced significantlyMany of today’s designs are engineered specifically to handle demanding industrial and municipal applications, and to operate at the pressures these applications demand.

It stands to reason that, the more robust and durable a chemical metering pump is, the greater the upfront price may be. However, the initial expense is offset by a lower total cost of ownership.

The Canadian Infrastructure Council has released Canada’s first National Infrastructure Assessment (NIA) amid a growing housing crisis driven by rapid population growth and a pace of housing delivery that cannot keep up. The urgency is underscored by the report’s finding that more than $126 billion worth of housing-enabling infrastructure is already in poor or very poor condition and at risk of near-term failure.

The report warns that many of the systems required to support new homes, including water, wastewater, transit, and waste management, are aging, lack capacity, and are increasingly vulnerable to climate impacts. Building Foundations for Tomorrow: Assessing Housing-Enabling Infrastructure Across Canada brings together population projections, infrastructure asset conditions, and climate considerations at a national

scale for the first time.

“Grounded in data, research, and insights from across sectors and regions in Canada, this first NIA highlights both the scale of Canada’s core infrastructure challenges and opportunities ahead,” said Jennifer Angel, Chair of the Canadian Infrastructure Council, in a statement.

According to the assessment, housing construction cannot accelerate without parallel investments in the systems that make communities functional and livable. Water and wastewater networks, waste management systems, public transit, and active transportation infrastructure are described as essential foundations that must keep pace with population demands and climate realities.

The report states that in 2022, more than 11% of Canada’s water and wastewater assets were rated in poor or very poor condition, representing an estimated $107 billion in infrastructure at risk. Water losses have also worsened, as leakage increased from 13% of total potable water use in 2011 (673 million litres) to 17% in 2021 (806 million litres). That loss is nearly equivalent to all the potable water consumed in British Columbia in 2021 (807 million litres).

Canada has long had higher leakage rates than peer countries, largely due to insufficient leak detection, repair, and other water loss control practices. These gaps also drive higher energy and resource use and leave systems more vulnerable to water main breaks and other service disruptions.

Total potable water use in Canada reached 4.9 billion m³ in 2021. Households accounted for the largest share at 55%, followed by industry at 28%, with distribution system losses making up the remaining 17%.

Even with a decade-long decline in water use, Canada’s per capita consumption remains high by global standards. In 2021, average daily use across all end users, including water lost through leakage, was 401 litres per person, down from 485 litres in 2011. However, this is still significantly higher than most peer countries.

The report draws on extensive engagement with experts and interest holders across the country, reflecting a wide range of regional perspectives. The Council says this input has helped build a more coordinated and evidence-based approach to long-term planning. Key insights from the report include.

• Better management and maintenance of existing infrastructure are essential to reduce risks and costs.

• Higher-density development makes more efficient use of existing infrastructure and supports green space preservation.

• Access to clean water, sanitation and public transit and active transportation remains uneven across the country.

• Infrastructure planning must reflect regional and community-specific conditions, including population and climate.

• Complex approval, regulatory layers and governance structures, together with aggregated taxes and charges, slow down housing construction.

• Labour shortages and supply chain issues are increasing costs and causing delays.

• Public funds alone are insufficient; private sector participation is crucial.

• Many infrastructure systems were designed for a stable climate and are not resilient to current and future conditions.

• Reliable, accessible data is needed to support infrastructure decision-making at all levels.

• Nature should be integrated into how we plan, design and build infrastructure.

Meeting Canada’s housing and infrastructure needs over the next 25 years will require what the assessment calls a “transformative shift” in how infrastructure is planned, financed, maintained, and delivered. The Council intends the National Infrastructure Assessment to serve as a resource for governments, operators, and investors as they navigate these decisions.

Canada updates drinking water guidance for radionuclides

By ES&E Staff

Health Canada has updated its technical guidance on radionuclides in drinking water, setting maximum acceptable concentrations (MACs) for the radioactive substances most commonly found in Canadian water supplies and outlining monitoring, treatment, and risk management expectations for utilities.

The guideline establishes MACs for three naturally-occurring radionuclides: lead-210 (Pb-210), radium-226 (Ra-226), and radium-228 (Ra-228), all of which are identified as the most significant contributors to radiation from drinking water in Canada. The limits are based on a reference radiation dose of one millisievert

per year (mSv/y), assuming an average daily water consumption of 1.53 litres.

Health officials emphasize that exceeding a MAC does not pose an immediate health risk, but it does trigger further investigation and follow-up by water system operators.

The guidance applies to water as consumed at the tap, meaning sampling and monitoring should reflect finished drinking water rather than untreated source water. For systems that treat water prior to distribution, monitoring should occur after treatment, as many radionuclides can be reduced through treatment processes. In most cases, radionuclide concentrations are not expected to change

significantly within the distribution system, making post-treatment or reservoir sampling appropriate.

The technical document was developed in collaboration with the Federal-Provincial-Territorial Committee on Drinking Water and draws on international health risk assessments, including dosimetric models released by the International Commission on Radiological Protection in 2007.

Radionuclides occur naturally in the environment, and Canadians are routinely exposed to background radiation from cosmic and terrestrial sources. While natural sources account for more than 98% of radiation exposure (excluding medical sources), drinking water is typically a minor contributor. The guidelines apply under routine operating conditions for both existing and new water systems and do not address nuclear accidents, which fall under provincial emergency response plans.

A screening criterion equivalent to a dose of 0.3 mSv/y has also been established for adults. If this level is exceeded, the water remains acceptable for children over one year of age and adults, but Health Canada recommends using an alternative water source, such as bottled water for the preparation of infant formula.

While elevated levels of radionuclides other than Pb-210, Ra-226, and Ra-228 are rare in Canadian drinking water, the guideline includes reference concentrations for additional natural radionuclides, such as polonium-210 and radon-222, as well as several artificial radionuclides. These substances are generally present at very low levels in the Canadian environment.

Higher concentrations of natural radionuclides may occur in limited areas, particularly where groundwater interacts with uranium-bearing rock, or where industrial activities such as uranium mining are present. Artificial radionuclides, originating from historical

Health officials emphasize that exceeding a MAC does not pose an immediate health risk, but it does trigger further investigation and follow-up.

nuclear weapons testing or nuclear facilities, are typically detected only at trace levels in Canada.

The primary health concern associated with long-term exposure to lowlevel radiation is an increased risk of cancer, as ionizing radiation can damage DNA if cellular repair mechanisms fail.

At the municipal scale, treatment technologies such as reverse osmosis, ion exchange, and lime softening can effectively remove most radionuclides from drinking water. Utilities are advised to consider that treatment residuals may contain low-level radioactivity, requiring appropriate handling and disposal. Sim ilar treatment options are available at the residential level, with no special precau tions generally required for homeowners.

The guideline also highlights the potential for radionuclides to accumulate in distribution system piping under cer tain conditions. Utilities are encouraged to include radionuclides in monitoring and distribution system management plans where source water concentrations warrant it. They should also apply best practices that limit corrosion, maintain stable water quality, and reduce distur bances that could release accumulated contaminants.

Radon remains the largest contributor to radiation exposure for most Canadians, primarily through inhalation rather than drinking water. Because radon in indoor air can originate from multiple sources, Health Canada does not set a drinking water MAC for radon. Instead it recom mends indoor air testing and mitigation when levels exceed national guidelines.

Overall, regulators note that radionu clide concentrations above MACs are

Accelerating water data validation with AI and machine learning

By Brian Gouge

Data is essential for monitoring water availability and quality, identifying risks and opportunities, informing policies and practices, and ensuring accountability and transparency among stakeholders. Organizing the world’s water information for faster, better decision-making requires the assurance of accurate, quality data. New advancements in data validation using artificial intelligence (AI) and machine learning (ML) are helping to speed up the review and correction of time series data for water managers.

ADDRESSING INCONSISTENCIES

Corrections of data can vary, based on who is reviewing the information. Even when an organization has standards in place, it can still be a matter of subjectivity. This is compounded by the fact that the amount of data is rapidly growing, as sensor technology is affordable, accessible, and easy to deploy, and monitoring of systems is expanding. This can result in massive backlogs of data to review. With limited staff, the process can be rushed and steps for quality assurance missed.

NEW TOOLS FOR QUICKER REVIEW OF TIME SERIES DATA

New cloud computing services are using statistical and machine-learning for data validation. By using a cloud toolbox to connect to a time-series database, users can select locations and data sets for review and receive recommendations for data corrections. In the initial setup, existing data sets are scanned and the software will use that information to recommend a set of validation rules for each of those data sets.

These rules are informed by previous data corrections that have been made by staff, as well as validation algorithms. As such, machine learning begins.

Once the recommended rules are set up, users can review them, accept them as is, or modify them based on circum-

Dataset before/after shows the raw data (green) and detected anomalies (red and cyan) and what the signal looks like after it is corrected (blue).

Data with detected anomalies highlighted. Below is shown an up-close view of each of the anomalies.

stances, perhaps specific to a location. Users can choose what action to take when the conditions for one of those rules are met. For example, if you have a threshold value and you want to see data that is above or below a threshold deleted, you can then set up automatic actions to take.

You can also set up rules to not have an automatic action, but instead just alert staff to review that data and make a manual correction to something that may be anomalous.

To help improve the overall ability of data managers to detect anomalous data, a rate of change rule can be applied. If there are rapid changes in time series values, operators can receive an alert to

determine whether something needs to be done at the site, or if data needs to be corrected. There are also tools for flatline detection, which can help indicate if a sensor may be offline. Seasonal parameters can be applied at specific times of the year to accommodate variations in supply and demand.

The goal of AI and machine learning in data validation is towards automation, so that machines do the routine work and staff focus on decision making. Managers can configure a correction as a suggestion by the machine; in which case it would need to be approved. Or, if that suggestion has been successfully approved several times, managers may decide to let the machine just do it

automatically. So, while automation is key to streamlining data validation, data managers can gain confidence in the results before they make the switch from human oversight to automation.

THE POWER OF DASHBOARDS

Once rules are set up, dashboards provide a high-level view of the rules where conditions have been met, where there is potentially anomalous data, or indications of early problems at a site. Using AI and machine learning to recommend automated corrections is paving the way for data reviewers to quickly assess what information, or what data sets, need to be evaluated and corrected in dashboards.

Visually viewing a snapshot of organized data allows managers to make decisions quickly as to whether to go out into the field to address an issue, or to make quick data corrections so that the data can be approved and sent out to stakeholders. For example, a manager may look at the dashboard before

coming in to see if sites are operating as expected. Maybe there is an issue with battery voltage, or an erratic sensor, that makes this a day for field work. Or, if everything is operating as expected, then it’s a good day to be in the office.

The advantage of a cloud-based solution is that dashboards are accessible remotely. If staff are already in the field, or on a multiple-day field trip, they can use the dashboard to determine which locations to go to next and determine what kind of work needs to be done at that location before they get there.

LOCATION-SPECIFIC PARAMETERS

Data correction tools can be set up to be user and location-specific, meaning the dashboard can be tailored around locations and tied directly to user credentials. For example, if an operator is responsible for 10 locations, they can set up the rules and the alerts for them. This allows staff to focus only on their locations and not affect other site data, or managers.

Cutting-Edge Tornado Mixing Technology

However, settings can be easily shared between different users if that makes sense, which is often the case in larger organizations. Rules that are location and dataset-specific provide consistency with the evaluation of data and recommendations for correction or assessment. Cloud computing services use a combination of statistical and machine-learning approaches for data validation. Over time, the system will learn what sort of rules may need to be applied, or what sort of corrections are being made. It then may recommend those corrections more frequently in the future. The combination of AI and machine learning is helping to propel water organizations to address and clear the backlog of data for quality assurance.

Reliable Performance

The crucial role of Ontario land surveyors in underground utility mapping

By Christopher Oyler and Nigel Day

The importance of Ontario land surveyors in mapping underground utilities cannot be overstated. As urban areas expand and aging infrastructure becomes increasingly complex to manage, the demand for precise utility mapping continues to grow. Accurate mapping helps prevent accidental utility strikes, which can cause costly damages, project delays, and safety risks. By offering these essential services, Ontario land surveyors have become indispensable to the future of construction, public works, and urban planning.

ENHANCING SAFETY AND COMPLIANCE

Safety is a top priority in construction and utility management. Excavating or drilling without accurate utility mapping can result in gas leaks, electrical hazards, or water main breaks, posing serious risks to workers and communities. Ontario land surveyors mitigate these dangers by providing detailed utility maps that comply with safety regulations, helping projects avoid penalties and ensuring a safer work environment.

Organizations like the Ontario Regional Common Ground Alliance (ORCGA) are instrumental in promoting utility damage prevention. Following Canadian Common Ground Alliance (CCGA) best practices, ORCGA offers training programs like the Damage Prevention Technician course and tools like the Damage Information Reporting Tool (DIRT) to track infrastructure damage. Ontario land surveyors actively participate in these initiatives to enhance on-site safety measures.

ADDRESSING THE CHALLENGE OF UNRELIABLE UTILITY RECORDS

Ontario land surveyors play a critical role in accurately identifying underground infrastructure, including water pipes, gas lines, electrical conduits, and communication cables. However, outdated or unreliable utility installation records often complicate utility locates.

Older measurement technologies and practices have left many utilities inadequately documented, while others have been installed outside designated easements, infringing on property rights. These situations necessitate boundary retracement surveys.

By law, only Ontario land surveyors are authorized to delineate and opine on real property boundaries. Their expertise

ensures clarity and compliance with legal requirements, safeguarding property rights and project integrity.

RELIABLE DATA: A SOLUTION FOR INFRASTRUCTURE DEVELOPMENT

Accurate utility mapping is essential for avoiding conflicts between new projects and existing utility networks. Ontario land surveyors provide precise data that ensure utilities are accounted for during the planning phase of infrastructure projects such as road expansions, building construction, or renewable energy installations. This proactive approach reduces risks and prevents costly operational disruptions or legal liabilities.

Utility strikes remain a significant cause of construction delays. Damage to improperly mapped or unmarked utilities can halt progress, leading to expensive repairs and missed deadlines.

Engaging Ontario land surveyors before construction begins allows project managers to avoid such setbacks, ensuring timelines are met and legal disputes minimized.

LEVERAGING TECHNOLOGY FOR PRECISION

Technological advancements have transformed underground utility mapping. Ontario land surveyors utilize tools such as ground-penetrating radar (GPR), electromagnetic locators, and Geographic Information Systems (GIS) to produce detailed subsurface data. These technologies enable the creation of three-dimensional models of underground utilities, which are invaluable for project planning, facility management, and sustainable urban development.

THE IMPORTANCE OF SURVEY MONUMENTS

Survey monuments, often damaged or destroyed during construction, are critical for maintaining accurate land bound-

aries and easements. These markers not only define property limits but also indicate areas encumbered by potentially hazardous underground utilities.

However, their destruction due to utility installations and other construction activities poses a growing challenge.

Permanent records, such as “as-built drawings,” should be created to reference the location of buried utilities relative to boundary markers. These records enhance the accuracy of GIS databases and ensure that essential information is easily accessible for future projects. Clear and accurate documentation, combined with preserved survey monuments, can significantly reduce the need for repetitive utility locates.

SUPPORTING SUSTAINABLE DEVELOPMENT

Ontario law mandates the identification of underground utilities before construction begins, with non-compliance resulting in fines, legal action, or project shutdowns. Ontario land surveyors

ensure compliance by providing utility maps that meet regulatory standards and collaborating with utility companies to verify and update outdated records.

Accurate utility maps also improve communication among stakeholders, including engineers, architects, contractors, and utility providers.

Reliable data helps teams identify potential conflicts, make informed decisions, and avoid miscommunication, leading to more efficient project execution.

The legal tightrope of road salting in Ontario

Unlimited contractor liability driving up insurance costs, coalition says

By David Nesseth

As Ontario edges closer to establishing a statutory standard for road salting, municipalities are grappling with a familiar winter dilemma: how to keep roads safe with one eye on the weather and the other on the courtroom.

That tension was at the centre of a recent Ontario Water Works Association webinar. Environmental lawyer Chris Hummel of Gowling WLG revisited a series of Ontario court cases showing how sodium chloride use, or restraint, can expose municipalities to liability from both injured motorists and neighbouring landowners, with costly legal and environmental consequences.

As it stands, the Municipal Act, 2001 is one of the key legal guides for salting

in Ontario, with Section 44 on maintenance stating that municipalities must keep roads “in a state of repair that is reasonable” in the circumstances.

“The key word is reasonable,” Hummel says, explaining the background of several Ontario-based lawsuits where municipalities’ actions, or lack thereof, were under the microscope when it comes to salting.

Hummel says that without an existing common law standard for municipalities to gauge an approach to road salting, civic leaders must balance their salting practices.

This means risking liability for personal injuries (slips and falls, automotive accidents) against the application of excessive amounts of salt that could harm off-site properties and create liability in civil actions for nuisance or negligence.

“It ends up being like a sort of spectrum, or if you like a tug of war,” says Hummel, who is also involved with the Ontario Road Salt Management Advisory Committee (ORSMAC).

MUNICIPALITIES PUSH FOR A PROVINCIALLY-ENDORSED STANDARD

Faced with that legal uncertainty,

some municipalities and industry groups argue the problem isn’t how much salt is used, but the absence of a clear, provincially endorsed benchmark. To ease the burden of the balancing act, organizations, such as the Ontario Salt Pollution Coalition, have been lobbying for a provincial salting guideline.

It gained the support of nearly 30 businesses and municipalities in 2025. They want, in part, for Ontario to work with key stakeholders to develop limited liability legislation. This would include enforceable contractor training and a single set of provincially-endorsed standard best management practices for snow and ice management.

“Unlimited contractor liability is making it difficult or expensive for snow and ice management contractors to obtain insurance coverage, resulting in contractors leaving the business, thereby making it difficult for municipalities and private owners to find contractors,” the coalition states in a draft resolution for the Ontario government.

Canada’s EcoFiscal Commission has estimated the economic and environmental damage of winter salt to Canada at $4.8 billion per year, which would prorate to about $2 billion per year in Ontario, the coalition says.

WHEN SALT ENDS UP IN COURT: KEY ONTARIO CASES

One of those municipalities supporting the coalition is the City of Cambridge, where local officials found themselves embroiled in a $9-million salt lawsuit in 2013. A local business accused the city of road salt leaching through the soil of a public works yard and contaminating the private property.

While the city admitted that a level of leaching occurred, the lawsuit ultimately failed due to the company’s inability to prove any negative financial impact. This was despite claims the salt impacted further development on the property. Ultimately, the judge awarded Cambridge nearly $500,000 in legal costs.

“I raised this to illustrate that people might sue you if you are a municipality or a landowner who is storing salt and it seeps into the groundwater,” explained Hummel.

Personal liability cases are far more common than contamination lawsuits, but an example of a successful Ontario environmental-based salt lawsuit arose in 2016. Like the Cambridge case, it too involved salt storage, as opposed to salt application.

In the end, a man ended up paying a $16,000 restitution fine to his neighbour as the result of salt damage to a row of tall, mature cedar trees along the property line. Many turned brown, the neighbour argued, and those next to the non-waterproof salt storage structure were affected by water runoff.

More worrying to municipalities was the 2015 court ruling that awarded an Ontario farmer more than $100,000 as the result of road salt damage to crops by the County of Lambton.

At the time, many municipalities backed the Ontario Good Roads Association to criticize the ruling as having failed to consider a municipality’s duty or responsibility to salt and provide safe roadways for travel.

“The law requires us to perform winter maintenance and we have now officially been punished for conducting winter maintenance,” the county’s clerk told reporters after the ruling.

It’s exactly the sort of catch-22 that Hummel and the coalition argue that

a statutory standard for salting could prevent.

LEARNING FROM OTHER MODELS

Hummel points to New Hampshire in the U.S. as an example of solving the salting conundrum. The northeastern state actually became the first U.S. state to use road salt for de-icing, starting with experiments in 1938.

By 2013, New Hampshire developed its RSA 508:22 Liability Limited for Winter Maintenance law. It shields anyone certified by the department of environmental services’ Green SnowPro Certification program from liability arising from snow and ice maintenance.

This also enables contractors, and those who hire them, to ensure that they are protected from liability by using published best practices, says Hummel.

The law essentially provides a legal definition of what is “reasonable”, which is the question often asked in Ontario salting cases, says Hummel, coming continued overleaf…

back to the maintenance definition in the Municipal Act, 2001. But the Clean Water Act, 2006, and the Environmental Protection Act also play roles in salt guidance, he notes.

Another element at play around personal injury is landowners’ liability under the Occupiers’ Liability Act, 1990. Again, the legislation focuses on what is “reasonable” in terms of keeping people safe on the premises. Commercial parking lots, for instance, have always been recognized as one of the largest contributors to salting.

Few would argue against the effectiveness of road salting in reducing accidents. In a 2014 report created for the Minnesota Pollution Control Agency, a comparative study of salted and unsalted roads showed that winter accidents may be reduced by up to 88% with a 10% reduction in crash-related cost when drivers regain frictional resistance.

When it comes to personal injury, Hummel notes the 2010 case of Frank vs. the Municipality of Central Elgin as a key moment in road salt litigation. During the day of a snowstorm, the woman hit an icy patch on the road and collided with an oncoming truck, injuring her head. She sued Central Elgin for negligence, alleging city staff failed to maintain the road in a reasonable state of repair.

But the Ontario Superior Court ruled that Central Elgin had adequately salted the road shortly before the accident, and it may have been light blowing snow that had delayed the salt’s effectiveness.

“I think cleverly they relied on the Ontario Good Roads Association standards and guidelines about appropriate rates of salt use that are sufficient to protect against dangerous conditions,” Hummel says of Central Elgin’s position in the lawsuit. “They could have done more, but there was no evidence to say that they should have used more [salt].”

The Ontario Court of Appeal dismissed the appeal.

Relying on the rates of salt use established by the association was key to the victory, as it can’t be held to a standard of perfection, says Hummel. It’s a major reason why groups such as the Ontario Salt Pollution Coalition are lobbying provincial officials for a clear standard for salt application.

In a 2018 best practices guide from the Ontario Good Roads Association and Conservation Ontario, dry salt (or sodium chloride NaCl) application rates range between 100-200 kg/ two-lane km, depending on how cold it is, applied at the centre line and a vehicle speed of 40 km/hr. Adapted from Snow and Ice Management Association data, about 1 kg of salt will melt 46 kg of ice.

One 2020 Norwegian study suggests that Canada has the highest rate of road salt application of all cold countries, reaching an annual consumption rate of six tonnes per kilometre of road.

The best practices guide also makes recommendations on elements, such as weather monitoring and equipment as factors for local governments to consider for salting.

At a national level, Environment and Climate Change Canada published the Code of Practice for the Environmental Management of Road Salts in 2004, following road salt being classified as a hazardous substance under the Canadian Environmental Protection Act, 1999. Then in 2014, the department

set seven performance indicators and national targets for provinces and municipalities to monitor the effectiveness of the code.

The code doesn’t focus on application rates, but instead provides guidance for identifying salt vulnerable areas where an action plan may be required, storage recommendations, and the advantages of pre-wetting or pre-treated salts.

The Ontario Salt Pollution Coalition is also lobbying to establish mechanisms for monitoring ecological and water impacts, reporting water quality progress, and reviewing databased policy revision needs.

In places such as Georgina, Ontario, which is also a supporting municipality of the coalition, local officials have been working for years to reduce salt application rates, as Lake Simcoe’s chloride levels continue to escalate to a point where some fear for the future of its aquatic life. The community has also been experimenting with a pre-treated salt that melts at a lower temperature and therefore can be applied less.

ENVIRONMENTAL COSTS EXTEND BEYOND WATER

Another growing concern around salting practices is the risk of corroding critical infrastructure such as bridges and watermains, plus the roads and the vehicles driven on them. Some economic analysts have estimated that a cost of at least $615 is added per ton of salt used for roadway infrastructure and $113 per ton of salt for vehicle infrastructure.

In Calgary, for instance, investigators found evidence that salt was a factor in the dramatic feeder main break that occurred in 2024. High chloride levels in the soil at various locations, as well as severe damage and corrosion impacting the pipe’s prestress wires, all played roles in the pipe’s eventual failure. “Elevated soil chloride concentrations are believed to be related to road de-icing activities using sodium chloride,” states the Associated Engineering report.

That same year in Ottawa, local officials stated that six decades of road salt irreversibly rusted out the 123-year-old interprovincial Alexandra Bridge, which is now set to be torn down.

New technologies, however, continue to provide some promise, such as porous pavement engineered to reduce runoff from roads. Or in Saskatoon, where an associate professor at the University of Saskatchewan’s College of Engineering, Dr. Haithem Soliman, is currently investigating ways to build roads that will be less affected by cold temperatures. He says communities may need to change their construction methods or the materials being used on roads.

Vaughan begins $224M Black Creek Renewal Project to protect downtown from flooding

By ES&E Staff

The City of Vaughan, Ontario, has officially broken ground on the Black Creek Renewal Project, a $224-million flood protection and environmental restoration initiative designed to transform the Vaughan Metropolitan Centre (VMC) and strengthen its resilience to climate change.

City officials recognized the need for major flood infrastructure improvements following heavy rainfall in the summer of 2005, that caused significant flooding in the Black Creek area. The resulting Black Creek Stormwater Opti-

mization Study Master Plan Environmental Assessment led to the creation of the renewal project.

The three-phase construction plan got underway in November 2025 and is scheduled for completion by 2031.

In addition to reducing flood risks, The Black Creek Renewal Project aims to enhance the local natural heritage system and create new green spaces along the Black Creek corridor between Highway 7 and Highway 407.

Phase 1 involves construction of Edgeley Pond and Park, including new streetscaping along Jane Street, which is currently underway and expected to be completed by the end of 2027. This phase also includes stormwater management system upgrades. Phase 2 consists of upgrades to the culvert under Highway 7, while Phase 3 includes the renewal of the Black Creek waterway between Highway 7 and Highway 407.

The project is being funded through a partnership between all three levels of government. The Government of Ontario is contributing $35 million through the Municipal Housing Infrastructure Program’s Housing-Enabling Water Systems Fund, while the federal government is providing $23 million. The City of Vaughan will contribute the remaining $166 million.

First Canadian database of mine impact assessments reveals transparency gaps

Dalhousie University researchers in Halifax have compiled the first-ever national database tracking environmental impact assessments (IAs) for Canadian mines and quarries over nearly five decades. The findings point to widespread gaps in transparency, consistency and public access to information.

The database, published in the journal FACETS, catalogues 266 impact assessments for 227 mining and quarrying projects proposed between 1974 and 2023 across 13 federal, provincial and territorial jurisdictions. The projects span commodities from coal, peat and oil sands in earlier decades to today’s surge in demand for gold, silver and critical minerals such as copper and nickel.

“There is a patchwork of IA regimes and public registries across Canada that collect and share relevant documents associated with mining development,” the study states.

Canada currently has roughly 200 active mines and 6,500 quarries producing 60 different commodities, the study states. Larger new projects typically undergo environmental assessments to predict potential impacts and help regulators decide whether to approve them and under what conditions.

But the research team, led by Dr. Alana Westwood of Dalhousie’s School for Resource and Environmental Studies and PhD candidate Ben Collison, found notable shortcomings in how those assessments are documented and shared. Despite legal requirements in many

jurisdictions to make assessment information public, about 20% of project files were either incomplete or unavailable.

“Due to the incompleteness of regulator registries, there are many data gaps in both the list of projects and the key metrics we extracted,” the study states. “Nevertheless, researchers can use our database to further elaborate on jurisdictional, economic, and policy trends.”

The team also uncovered inconsistencies when comparing mine impact assessments submitted to provincial and federal regulators for the same project. Some 60% of paired assessments showed major discrepancies in project size, footprint or duration, raising questions about regulatory alignment.

Westwood and Collison say impact assessment processes could play a central role in data sharing and public engagement as Canada advances new industrial developments, including mines needed for the clean energy transition. They argue that better coordination among governments would help position Canada as a global leader in responsible resource development.

The new database is now available to policymakers, regulators, researchers and the public as a tool to better understand the environmental implications of mining across the country.

Sediment restoration quietly reshaping the future of B.C.’s Fraser River Estuary

By Chantelle Abma

On the Fraser River Delta, near Richmond, British Columbia, an experiment in coastal engineering and ecology is reshaping how we think about coastal resilience. The Sturgeon Bank Sediment Enhancement Pilot Project, led by Ducks Unlimited Canada (DUC) with government and research partners, is testing how dredged sediments can be strategically placed to restore tidal marshes, buffer communities against flooding, and support struggling salmon populations.

A CENTURY OF LOSS

Over the past 100 years, the Fraser Estuary has been heavily altered by human activity. Diking, channelization, and sediment removal for navigation have drastically reduced the supply of fine sediments that once built and sustained intertidal marshes. As a result, vast marshes that previously nurtured juvenile salmon and countless migratory birds have died off, leaving tidal flats exposed and communities more vulnerable to storm surges.

THE PILOT PROJECT

Launched in 2022, the Sturgeon Bank pilot project is one of the first large-scale attempts of its kind in Canada to beneficially reuse dredged sediment in an estuarine environment. The concept is simple but innovative: take sediment dredged from the Fraser River’s navigation - and side-channels and place it on targeted areas of the tidal flat. There, natural forces like tides, waves, and wind redistribute the material, mimicking the processes that historically sustained marsh formation.

The project’s goals are threefold:

• Rebuild tidal marsh habitat critical to juvenile Pacific salmon and migratory birds.

• Strengthen coastal resilience by restoring natural buffers that reduce wave energy and flooding risks.

• Demonstrate feasibility of beneficial sediment reuse in a dynamic, estuarine setting.

EARLY PROGRESS AND MONITORING

Coastal engineers, geomorphologists, and ecologists are carefully monitoring how sediments move once placed. Elevation surveys, drone imagery, and vegetation assessments track how quickly tidal flats respond and whether sediment stays in the desired zones. As a pilot project, it is designed for learning and adaptation. Many opportunities for improvement and increasing cost-effectiveness have been identified.

For example, understanding the type of sediment from different dredging sources has changed the method and location of dredging and sediment pumping onto Sturgeon Bank. Each year, the pipeline mobilization and anchoring methods are

refined to minimize impacts to the mudflat environment and protect the equipment from damage during strong winds and storms.

Over time, these vegetated areas are expected to function much like natural marshes, slowing water, trapping additional sediment, and providing habitat complexity. By accelerating natural processes, the pilot tests whether engineered interventions can “jumpstart” marsh recovery in places where natural supply is too limited.

BENEFITS FOR SALMON AND BIODIVERSITY

To determine the success of the pilot, monitoring sediment movement and biological outcomes may be even equally important. Juvenile Chinook and other salmon species use tidal marshes as nurseries, feeding in the shallow, protected waters before heading to sea. Studies have shown it is likely that habitat loss in the Fraser estuary contributes to the decline of some salmon populations. By restoring marsh platforms, the pilot project aims to increase prey availability for young fish and improve overall estuarine function. At the same time, new marsh areas benefit migratory birds, invertebrates, and other wildlife that depend on the estuary’s food webs.

ENGINEERING CHALLENGES

The Sturgeon Bank pilot faces significant technical hurdles familiar to environmental engineers. For example, only suitable dredged materials can be reused, requiring close coordination with dredg-

ing operations. Sediment must be placed in locations where hydrodynamic forces will help, not hinder, retention. Estuarine systems are dynamic which means predicting sediment movement is complex and requires adaptive management. Finally, approvals involve multiple agencies and must align with ecological and cultural priorities.

LOOKING AHEAD

After three years of monitoring, the project continues to show promise. If successful, the Sturgeon Bank model could be scaled up across the Fraser delta and adapted to other estuaries facing similar sediment deficits.

For environmental engineers, the lessons go beyond technical performance. The project demonstrates the value of engineering with nature, using physical interventions to restore processes rather than control them. It also highlights how infrastructure decisions, such as dredging for navigation, can be reframed as opportunities for ecological gain when

sediments are repurposed rather than discarded.

A MODEL FOR FUTURE RESILIENCE

Coastal communities worldwide face the twin threats of sea-level rise and habitat loss. The Sturgeon Bank Sediment Enhancement Pilot Project offers a tangible example of how beneficial reuse of sediments can contribute to both ecological restoration and climate adaptation.

For Canada, it is also a reminder that engineering expertise and ecological knowledge are most powerful when combined. At Sturgeon Bank, sediment is more than material; it is the foundation for rebuilding marshes, reviving salmon populations, and protecting communities from the next storm.

U.S. DOE commits nearly $25M to projects recovering critical minerals from wastewater

By ES&E Staff

Research teams are developing technologies to extract and recover critical minerals and ammonia from wastewater plants.

Credit: don, stock.adobe.com

The U.S. Department of Energy’s (DOE) Advanced Research Projects Agency–Energy (ARPA-E) has awarded nearly $25 million to 10 research teams developing technologies that extract and recover critical minerals and ammonia from domestic wastewater streams.

The DOE says recovering the currently discarded resources could help reduce U.S. dependence on imported materials.

The new funding is part of ARPA-E’s Realize Energy-rich Compound Opportunities Valorizing Extraction from Refuse Waters (RECOVER) program, launched in 2025 to build secure, domestic supply chains for minerals used in energy, manufacturing and fertilizers.

“These minerals are called critical for a reason. They enable our nuclear reactors, advanced electronics, and energy storage technologies,” ARPA-E Director Conner Prochaska said

in a statement. “RECOVER will join the other initiatives in DOE’s critical minerals campaign to reshore the processing of critical materials and strengthen our domestic supply of these vital resources.”

The program focuses on technologies that could complement traditional wastewater treatment systems and turn agricultural, oil and gas, and mining wastewater into new sources of ammonia and metals such as lithium, cobalt and rare earth elements. DOE says wastewater streams contain enough of these materials to offset a major share of U.S. imports, but only if they can be recovered efficiently and at competitive market prices.

RECOVER projects aim to reduce the number of processing steps typically required to isolate and recover critical minerals from wastewater, while designing systems that can be integrated into existing or new facilities. The program’s goals include recovering up to half of the United States’ ammonia needs and the full domestic demand for key critical metals.

UNIVERSITY OF MISSOURI, COLUMBIA

AI-augmented ion-imprinted polymers are being used to target rare earth elements, such as neodymium, praseodymium and terbium in mining waste. The engineered polymer structures are designed to boost selectivity and cost-efficiency for recovering minerals from acid mine drainage and similar waste streams.

PHOENIX TAILINGS, WOBURN, MASSACHUSETTS

Specialized ligands are being designed to bind with critical minerals in dilute brines, allowing the complexes to be separated through fractional distillation. The approach could enable the recovery of pure salts at low concentrations.

CAROLLO ENGINEERS, COSTA MESA, CALIFORNIA

The company is creating a biotechnology platform that uses engineered ferritin protein nanocages to selectively capture metals, such as lithium, cobalt, nickel, dysprosium and neodymium from produced water. Machine-learning-guided protein design will be used to increase affinity for targeted metals. The process

is intended to operate under mild conditions and allow repeated regeneration of the nanocages.

Major investments strengthen stormwater system and safeguard B.C.’s Semiahmoo Bay

By ES&E Staff

Acombined investment of more than $9.8 million will not only create drainage infrastructure improvements in order to enhance stormwater quality in Semiahmoo Bay and manage flooding along Marine Drive in White Rock, British Columbia, but also deepen the partnership with a local First Nation.

The Marine Drive Stormwater Improvements project includes the installation of nearly two kilometres of new stormwater pipe, the design and construction of a

new pump station, the removal of existing aging infrastructure, and improvements to water quality at the outfall. The project also aims to enhance stormwater quality to preserve biodiversity and support the overall health of Semiahmoo Bay.

During flooding events in recent years, White Rock crews would remove drain covers to speed up the draining process. Local officials are currently working on updating the Drainage Master Plan.

White Rock’s current $320-million drainage network receives runoff from a total catchment area of 772 hectares, of which 229 hectares come from the City of Surrey. The majority of storm sewers

discharge directly into Semiahmoo Bay, or to Little Campbell River, through piped outfalls or culvert crossings.

There are approximately 100 km of storm sewers (with pipe sizes ranging from 100 mm to 1,325 mm), 1,821 catch basins, 1,179 manholes, 1,620 metres of ditches, and 1,872 metres of streams maintained.

To make the new stormwater project a reality, the City of White Rock and Semiahmoo First Nation formed a Drainage Memorandum of Understanding (MOU) to strengthen government-to-government relationships and advance collaborative infrastructure planning.

The signing of the Drainage MOU reflects White Rock city council’s strategic priorities of ongoing commitment to foster positive relationships with the Semiahmoo First Nation and consult on all infrastructure and climate change-related projects.

A new $6-million federal investment will also support the extension of Semiahmoo First Nation’s water and wastewater systems to safely and reliably service future housing development and connect a proposed 32-unit BC Housing development to the City of Surrey’s municipal systems.

Indigenous Services Canada also recently provided over $400,000 to the community for design upgrades to their water and wastewater systems, including the watermain along Beach Road, fire hydrants, and for electrical upgrades to the three sanitary lift stations.”

PFAS drinking water treatment implications for municipalities, water operators and consulting engineers

By Devendra Borikar

Per- and polyfluoroalkyl substances (PFAS) comprise a large class of synthetic organic chemicals (Figure 1) commonly referred to as “forever chemicals” due to the strength of the carbon–fluorine bond and their resistance to environmental degradation. PFAS are highly mobile in aquatic environments and have been widely detected in surface water and groundwater sources used for drinking water supply. Sources of PFAS contamination include industrial discharges, landfill leachate, wastewater treatment plant effluent, and the historical use of aqueous film-forming foams (AFFF). Their chemical stability and resistance to conventional treatment processes pose significant challenges for drinking water utilities and municipalities, water operators, and consulting engineers.

Epidemiological and toxicological studies have linked long-term exposure to certain PFAS compounds to increased risks of kidney and testicular cancers, immune suppression, reduced vaccine effectiveness, developmental effects, liver toxicity, thyroid disruption, and elevated cholesterol levels. These documented health concerns have prompted regulatory agencies to reassess acceptable PFAS concentrations in drinking water and pursue increasingly stringent regulatory values.

In 2024, Health Canada proposed a drinking water objective of 30 ng/L for the sum of 25 PFAS. The Ontario Ministry of the Environment, Conservation and Parks (MECP) is currently evaluating alignment with this proposed objective. It has adopted the principle of reducing PFAS concentrations to the lowest level reasonably achievable

Conventional drinking water treatment processes, such as coagulation, sedimentation, and rapid filtration, are largely ineffective at removing PFAS. Credit: enggartiasto, stock.adobe.com

Until new requirements are formally adopted, Ontario continues to rely on its 2017 interim advice value of 70 ng/L for the sum of 11 PFAS. Transitioning to a more stringent Ontario regulation would have substantial implications for drinking water systems that use PFAS-impacted surface water or groundwater sources, potentially requiring advanced treatment upgrades, operational changes, and enhanced monitoring programs.

Conventional drinking water treatment processes, such as coagulation, sedimentation, and rapid filtration, are largely ineffective at removing PFAS. Achieving compliance with a potential 30 ng/L objective typically requires advanced treatment

technologies and careful consideration of operational complexity, residuals management, and life-cycle costs.

Granular activated carbon (GAC) is widely used for PFAS control and is particularly effective for long-chain PFAS compounds. Short-chain PFAS exhibit lower adsorption affinity, resulting in earlier breakthrough and more frequent media replacement or regeneration. Effective operation requires routine monitoring of effluent PFAS concentrations, timely GAC replacement, and proactive carbon management strategies to control operating costs.

Ion exchange resins can achieve high continued overleaf…

removal efficiencies for both long- and short-chain PFAS and often provide longer run times than GAC. However, they are significantly costlier, and performance may be affected by competing ions such as sulphate, nitrate, and natural organic matter. Resin exhaustion, disposal, or regeneration requirements must be carefully evaluated during system selection and design. Although nanofiltration (NF) and reverse osmosis (RO) provide very high PFAS rejection, Ontario has few or no NF/RO systems at this time because source water quality across the province is generally good. Their application is limited by high capital costs, increased energy demand, and the generation of a concentrated reject stream that requires appropriate management or disposal. Robust pretreatment is essential for controlling fouling and scaling and for maintaining stable membrane performance.

Across all technologies, residual handling and disposal can account for 25 – 50% of total project life-cycle costs, underscoring the importance of pilot testing or site-specific evaluation. Table 1 summarizes key operational considerations for GAC, ion exchange (IX), and NF/RO systems from an operator perspective.

Residuals management is a critical and often underestimated component of PFAS treatment projects. GAC systems treating short-chain PFAS may require frequent media replacement due to early breakthrough. While IX systems typically offer longer run times, exhausted resins must be managed through approved disposal or regeneration pathways in accordance with local regulations.

PFAS-enriched concentrate stream that requires specialized handling. Disposal options are often limited, which can significantly increase project complexity and cost. Due to the persistence of PFAS, residual management strategies must address long-term environmental liability and regulatory compliance, reinforcing the need for comprehensive life-cycle assessments.

Pilot testing is an effective way to reduce uncertainty and compliance risk when evaluating PFAS treatment technologies. Pilot studies enable utilities to assess treatment performance under site-specific water-quality conditions, estimate design criteria, media life, and waste-generation rates, and develop reliable life-cycle cost estimates. Pilot data also support regulatory approvals and funding applications by providing defensible design parameters.

As drinking water systems transition from conventional to advanced PFAS treatment technologies, operator skill requirements increase. Targeted training programs are essential to ensure that oper-

ators are prepared to manage advanced monitoring requirements, process optimization, and residuals handling associated with GAC, IX, and membrane systems.

CONCLUSIONS

Ontario’s adoption of a total of 30 ng/L for 25 PFAS and the lowest level reasonably achievable principle for PFAS will likely drive increased implementation of advanced treatment technologies. Successful compliance will depend not only on technology selection but also on effective pilot testing, robust residuals management strategies, and enhanced operator training.

By integrating these elements, drinking water utilities and municipalities can manage regulatory risk while controlling the substantial life-cycle costs associated with PFAS treatment.

Initiating a flow measurement project

By Richard Delgadillo

Problems such as inflow and infiltration (I&I) that plague the wastewater industry are often associated with wet weather events that overwhelm collection systems and cause a myriad of maintenance issues.

Many large metropolitan cities have developed plans to become ‘smart cities,’ which include various improvements to their water utilities. The emphasis of ‘smart water’ typically falls on drinking water rather than wastewater systems, but recently there has been a movement to integrate wastewater into the larger IoT of water.

Wastewater flow meters, both closed pipe and open channel, offer wireless capabilities, a variety of communication outputs and data logging capabilities, and power options to suit application needs. These meters can connect to SCADA systems, overflow prevention basins, and many manufacturers offer ones that allow fully automated data integration into the utility’s management software.

These smart water meters have allowed cities to collect and review wastewater flow data in real time. Valuable sewer data is usually historical, so viewing reports about I&I incidents over time helps utilities detect patterns that may indicate aging infrastructure, blockages, or capacity constraints. Cities can then prioritize repairs and upgrades before expensive failures occur, reducing emergency costs and service disruptions.

Historical flow data can also benefit utilities in their flood and overflow prevention efforts, enabling modelling of wet weather impacts and potential overflow events based on past trends.

Staying proactive and developing an information-based approach to setting priorities and continuous improvements requires accurate, dependable, and ongoing data about the wastewater conveyance system. Permanently installed flow measurement devices are a guaranteed method of acquiring the much-

needed data to integrate into automated information management systems.

However, flow measurement is not the panacea for I&I, or future-proofing a wastewater conveyance system. Many technicians and engineers utilize a variety of tools and techniques in conjunction with flow measurement to gain a holistic understanding of their pipeline network and make informed decisions about daily activities, including acoustic devices, smoke testing, CCTV, GIS maps, and more.

Despite the size of a wastewater conveyance system, initiating a flow measurement project doesn’t need to be a large overhaul or investment from the beginning. It is best to begin with a small pilot program to evaluate the technology and experience the benefits and then expanding to add complexity over time. This will assist with onboarding staff to the technology, allowing for adequate data integration and analysis, and account for the utility’s budget.

Begin by prioritizing installation locations

near the

and compo-

maintained condition.

Whole-network programmatic sewer line flushing is very costly and is a slow process Rapid Assessment Technology Services (RATS Inc.) has redefined the assessment process by providing municipalities with comprehensive acoustic network condition data in a fraction of the time and cost required by the old costly flushing methods

The SL-RAT acoustic technology is a tool to triage municipal wastewater collection systems to identify blockage conditions and reduced carrying capacities. This smart information allows the municipality to identify systemic issues and swiftly react through various means of interventions to reduce the potential of failure (i e SSO spills, basement flooding). This saves the municipality time, money and resources and allows for: 1) prudent sewer system maintenance and level of service, 2) informing on asset management best practices, and 3) regulatory compliance

Municipalities now can focus their high-cost resources only on the small percentage of the network that represents a potential service disruption or imminent failure
