Vortex’s global growth in delivering trenchless rehabilitation products, technologies and services

Few companies have expanded as rapidly in the trenchless infrastructure rehabilitation sector as Vortex Companies. The global business now employs more than 1,500 people across 45 locations worldwide and offers a portfolio of more than 75 products and systems.

Dave Fletcher, Senior Vice President, who has spent more than 30 years in the trenchless industry, is responsible for strategic growth in the UK and Ireland, with a focus on the full suite of Vortex product offerings. Speaking with Trenchless Works editor Austen Lees, Fletcher says the company’s philosophy is rooted in a simple principle.

“At Vortex, everything begins with thinking big. That means looking beyond individual products or isolated repairs and focusing on how we can help utilities and contractors solve infrastructure challenges in smarter, more sustainable and more effective ways. Our growth has come from understanding that customers increasingly need complete solutions, products, technologies and services that work together to deliver long-term performance.”

A market driven by infrastructure pressure

Demand for trenchless rehabilitation technologies continue to grow globally, driven by ageing assets, environmental pressures and increasing regulatory scrutiny. Fletcher says North America has historically been one of the most dynamic and high-growth markets, largely because of strong regulatory enforcement around sewer infiltration and inflow.

“A major driver has been the long-term pressure applied by the Clean Water Act and the Environmental Protection Agency, which has pushed utilities to take infiltration and inflow seriously for many years. That kind of regulatory framework creates urgency, but it also creates opportunity for innovation, because utilities have to find solutions that are effective, practical and scalable.” That regulatory pressure has driven significant investment in rehabilitation technologies designed to seal and stabilise ageing networks.

“At Vortex, everything begins with thinking big. That means looking beyond individual products or isolated repairs and focusing on how we can help utilities and contractors solve infrastructure challenges in smarter, more sustainable and more effective ways.

Dave

Fletcher, Senior Vice President Vortex

“We have seen this same behavior in the UK with reoccurring AMP activity with similar resolve,” Fletcher says. “Public concern, media scrutiny and the environmental consequences of storm overflows are all increasing pressure on water companies to address the underlying causes of network failure rather than simply managing the symptoms. That is where trenchless rehabilitation has a major role to play.”

One of the biggest issues facing wastewater networks is groundwater infiltration entering systems through cracks, damaged connections and deteriorating manholes.

“When groundwater enters the system, it creates a chain reaction of problems. It overloads treatment works, drives up operational costs, reduces overall efficiency and, in many cases, contributes directly to storm overflows. It’s not just an engineering issue, it’s an environmental and financial issue as well.”

However, he emphasises that solving infiltration requires a whole-system approach. “You can line pipes all day long, but if you don’t deal with lateral connections, joints and manholes, the water will simply find another path into the network. Real rehabilitation means sealing the system as a whole. The most successful asset owners are the ones who recognise that you need a joined-up strategy, not a piecemeal fix.”

Rising demand for specialty application products and application systems

Within the rehabilitation market, Vortex is seeing particularly strong demand for its coatings and geopolymer technologies. Products such as GeoKrete® geopolymer mortar, WRC Approved, is designed to restore structural integrity while providing strong corrosion resistance in challenging environments.

“These materials are opening up opportunities to rehabilitate structures that, in the past, would have been extremely difficult or uneconomical to repair,” Fletcher says. “What makes geopolymer technologies so important is that they can deliver both structural renewal and durability in aggressive environments, while also supporting a more sustainable approach to infrastructure rehabilitation.”

GeoKrete can be applied using spin-cast or spray techniques and incorporate natural and high-performance materials, making them suitable for a wide range of infrastructure assets.

Alongside its flagship geopolymer, the company is also seeing growing demand for its corrosion resistant Quadex epoxies, such as Structure Guard® and Maverick grout systems designed to address infiltration and sealing challenges. All of these products are formulated in-house and undergo extensive third-party testing to meet industry standards.

“Groundwater infiltration is a massive issue globally, and it doesn’t matter whether you are looking at mature markets or emerging ones, utilities everywhere are facing the same fundamental challenge of protecting assets and controlling flows,” Fletcher says. “Having the right materials to seal, stabilise and extend the life of infrastructure is absolutely critical.”

Combining products and services

One of the factors Fletcher believes differentiates Vortex from many other suppliers is its combination of product manufacturing and services.

While the company’s products division has expanded significantly through disciplined organic

“Our founder and CEO Mike Vellano talks a lot about growing the industry together, and that is a philosophy we strongly believe in. If we can help expand the market, raise standards and increase confidence in trenchless solutions, then the whole sector benefits.

Dave Fletcher, Senior Vice President Vortex

growth and acquisitions, including the purchase of Applied Felts, rebranded as United Felts for North and South American operations, its service businesses continue to play a key role in product development and market adoption.

By operating service companies in the UK and Europe, Vortex can test and refine new solutions in real-world environments and bring proven technologies to market more quickly.

“Service businesses help new technologies gain traction,” Fletcher explains. “They are on site, they understand operational realities and they often have well-established relationships with utilities and asset owners. In many cases, they are the ones introducing new ideas into the network and demonstrating that those ideas can deliver in practice.”

“At the moment, there is so much work across the sector that it’s not really a point of tension,” Fletcher says when asked whether the dual role ever creates challenges with contractors who are also customers.

“Our founder and CEO Mike Vellano talks a lot about growing the industry together, and that is a philosophy we strongly believe in. If we can help expand the market, raise standards and increase confidence in trenchless solutions, then the whole sector benefits.”

The industry’s biggest constraint: people

Despite the strong outlook for trenchless rehabilitation, Fletcher says one of the biggest barriers to growth across the sector is the availability of skilled workers.

“The biggest challenge across the industry is people,” he says. “Most trenchless companies could grow much faster if they had access to more skilled individuals. Demand is there, the technology is there and the opportunities are there, but finding and developing the right talent remains one of the sector’s biggest constraints.”

Part of the challenge lies in how the sector is perceived. “From the outside, it may not always look like the most exciting industry,” Fletcher admits. “But the reality is very different. This is a technically advanced, fast-evolving sector where innovation is happening all the time. We’re not just talking about traditional rehabilitation methods anymore, we’re talking about robotics, advanced materials, sensors, software and data-led decision-making.”

Alongside rehabilitation materials, Vortex has expanded its portfolio to include sewer robotic systems, UV curing technologies and lining systems.

“It’s no longer just about fixing pipes,” Fletcher says. “The future of this industry is about combining physical rehabilitation with digital intelligence, using better data, smarter inspection and more advanced tools to help utilities manage assets more proactively and more efficiently.”

Improving awareness of those opportunities will be key to attracting younger professionals. “We need to do a better job of showing people that this is a modern, high-growth industry where they can work with advanced technology, solve real-world problems and build a meaningful long-term career. There is enormous opportunity here for the next generation.”

Unlocking the potable water opportunity

Looking ahead, Fletcher believes one of the most exciting growth opportunities for Vortex is in the potable water sector. Through its Vortex Water business, the company has been investing in both product innovation and installation methodology to

help meet the next major challenge in trenchless pipe rehabilitation: the renewal of clean water infrastructure.

“We see potable water as a major opportunity for the future,” Fletcher says. “Vortex has been investing in the right technologies, the right products and the right installation approaches so that we are ready to support utilities as adoption continues to grow.”

That momentum is already becoming more visible in other markets around the world, where they are increasingly embracing trenchless rehabilitation solutions for potable water networks. Fletcher says this reflects growing confidence in proven technologies and the benefits they can deliver, including reduced disruption, extended asset life and improved network performance. “That is encouraging because it shows what is possible when utilities have a clear pathway to evaluate and implement innovative rehabilitation solutions.”

In the UK, Fletcher believes the opportunity is equally significant, and that the industry is moving in a positive direction. While adoption has progressed more gradually, he says there is every reason to be optimistic about the future as awareness grows and the sector continues to explore new ways to modernise critical infrastructure.

“ Growth only has real value if you can maintain high standards, continue to deliver proven and repeatable solutions to customers.

“The UK has a tremendous opportunity ahead,” Fletcher says. “There is a growing recognition of the role trenchless rehabilitation can play in helping utilities renew assets more efficiently and sustainably, and we are excited about the potential for that market to follow suit in the near future.”

For Vortex, the focus is not only on supplying materials, but on bringing forward complete solutions backed by technical expertise, installation know-how and experience from other established markets.

“This is about more than technology alone,” he says. “It is about having the right methodology, the right delivery model and the right long-term vision to help utilities adopt these solutions with confidence.”

“Sometimes the biggest opportunity is not inventing something entirely new,” he says. “It is applying proven technologies in new areas where they can make a real difference. In many cases, the solutions already exist, and the opportunity now is to bring them into wider use.” For Vortex, that makes potable water one of the most important frontiers for the business and for the trenchless industry more broadly.

Act locally and think globally

As Vortex continues to expand globally, Fletcher says the company will maintain its focus on driving innovation in the trenchless infrastructure rehabilitation sector. “Our focus is on R&D, quality, and execution,” Fletcher says. “Growth only has real value if you can maintain high standards, continue to deliver proven and repeatable solutions to customers”, concluded Fletcher.

BRAWOLINER® liner system passes WRc infiltration test in UK

The BRAWOLINER® CIPP lining system from BRAWO Systems GmbH has successfully passed infiltration testing at the Water Research Centre in Swindon, demonstrating the liner’s resistance to groundwater pressure under controlled conditions.

The independent test confirmed the system’s performance in accordance with CP655 classifications 1 and 2, the current UK standard for evaluating infiltration resistance in cured-in-place pipe (CIPP) liners. Earlier testing of the liner was conducted in 2006 under the previous CP308 designation.

During the trial, the liner was subjected to simulated high groundwater pressure to evaluate its ability to prevent water ingress between the host pipe and the installed liner.

Leakproof performance under groundwater pressure

The test involved applying external water pressure equivalent to a five-metre water column (0.5 bar) for a period of 30 minutes.

According to WRc test observations, the installed liner remained completely leakproof during the pressure test. No infiltration was recorded between the host pipe wall and the outer surface of the liner, and the liner-resin composite matrix also remained watertight. The system was installed and cured under conditions including flowing water, with the test confirming that these conditions did not affect the liner’s installation, curing process or final water resistance.

No additional sealing measures required

The test was conducted without the use of additional sealing components, such as end sleeves or sealing tapes. Results showed that the liner system achieved a watertight seal against the host pipe without supplementary sealing technologies, potentially reducing installation complexity and on-site preparation requirements.

Long-term pipeline rehabilitation performance

The infiltration test also supports the liner system’s long-term objective in sewer rehabilitation: preventing both wastewater exfiltration into surrounding soil and groundwater infiltration into sewer networks. In addition to testing the liner-host pipe interface, the assessment confirmed that water resistance could

still be achieved even with an open incoming lateral connection and without additional sealing technology.

The certification under CP655 therefore verifies that a watertight connection between the liner and host pipe can be achieved under the tested conditions.

CIPP technologies such as BRAWOLINER® are widely used for trenchless pipeline rehabilitation, enabling operators to restore damaged sewer pipes with minimal excavation and disruption to surface infrastructure.

SOUTHERN WATER DEPLOYS

TBM FOR £100M SOUTHAMPTON LINK MAIN PIPELINE

Atunnel boring machine (TBM) is excavating sections of tunnel for a major drinking water pipeline project in Hampshire, as Southern Water advances construction of its £100 million Southampton Link Main scheme.

The 19 km pipeline project will strengthen the region’s water supply network by linking key water infrastructure between Otterbourne, Yew Hill reservoir near Winchester, and Rownhams water supply works on the outskirts of Southampton.

TBM installing pipeline beneath key infrastructure

Sections of the pipeline are being installed using trenchless tunnelling methods to avoid disruption to major infrastructure and environmentally sensitive areas.

A manually operated TBM named “Ancasta” is excavating 1.5 m diameter tunnels at depths starting at around 14 m below ground.

The machine weighs approximately 6.5 tonnes, measures 2.7 m in length, and began tunnelling operations in September 2025, with works expected to continue until May 2026. Although large portions of the pipeline are being installed using conventional open-cut construction, trenchless methods are being used where crossings beneath roads, railways and ecological sites are required.

Water network resilience project

According to Southern Water, the Southampton Link Main project is part of a wider infrastructure investment programme aimed at strengthening long-term water

supply resilience across the region. Ben Ring, Director of Major Projects at Southern Water, said: “The Southampton Link Main project has been underway since the middle of 2025 and there are many exciting aspects to major projects such as these. This is part of a wider set of projects designed to improve the resilience of our water network for our customers in Hampshire.”

The project is also expected to support environmental protection by reducing pressure on nearby rivers including the River Test and River Itchen.

Major UK water infrastructure partnership

Southern Water is delivering the scheme in partnership with MGjv, a joint venture between Galliford Try and M Group Water, alongside specialist tunnelling contractor HB Tunnelling. The full project is expected to take more than three years to complete.

TBM named by local schoolchildren

Following tunnelling tradition, the TBM has been given a female name for good luck. The name Ancasta was selected from suggestions submitted by local schoolchildren and references a pagan goddess associated with the River Itchen in Hampshire.

HINKLEY POINT C PREPARES TBM LAUNCH FOR 620M FISH RETURN TUNNEL

Engineers working on the Hinkley Point C nuclear power station in Somerset are preparing to excavate a 620-metre fish return tunnel, part of a major programme designed to minimise impacts on marine life in the Severn Estuary.

The works will use a small-diameter tunnel boring machine, allowing the tunnel to be constructed without surface excavation across the sensitive estuary environment.

A tunnel boring machine (TBM), named “Sarah Guppy” by local schoolchildren in honour of the 19th-century British inventor and engineer, will be used to construct the tunnel. The drive will create a tunnel measuring approximately 1.8m in diameter, designed to return fish safely to the estuary after passing through the power station’s cooling system. The tunnelling works are being delivered by the Kier BAM joint venture, with specialist support from Joseph Gallagher.

Protecting marine life

The fish return tunnel forms part of a three-part environmental protection system integrated into the design of the new nuclear facility.

Alongside the return tunnel, the system includes:

• Low-velocity cooling water intake heads, designed to slow the speed of water entering the cooling tunnels

• An acoustic fish deterrent system, intended to prevent fish from approaching intake structures

Together, the systems are designed to significantly reduce the risk of fish being drawn into the plant’s cooling infrastructure. According to project developer EDF, the combined fish-protection measures will cost more than £700 million and will deliver one of the most comprehensive marine protection systems installed at any power station globally.

Acoustic deterrent trials

The acoustic deterrent technology has been developed by Devon-based fisheries conservation specialist Fishtek Marine and tested in collaboration with Swansea University. The system uses ultrasonic signals to discourage certain fish species from approaching the cooling water intake. Researchers involved in sea trials reported the technology to be highly effective at redirecting fish away from sensitive areas.

Because the system is compact, it can be deployed and maintained without the need for divers, representing a significant operational improvement compared with earlier concepts that would have required hundreds of underwater loudspeakers.

Integrated protection system

The three elements of the protection system are designed to operate together.

Cooling water intake heads aligned with the tidal flow of the Severn Estuary will reduce water velocity at the intake point, allowing fish to swim clear even when they approach close to the structures.

Fish that do enter the system will encounter drum screens positioned ahead of the cooling-water pumps, which intercept them and guide them into the return tunnel before being safely released back into the estuary.

The Severn Estuary supports a range of migratory fish species and is recognised as one of the most dynamic tidal environments in the UK, meaning environmental protections are a key element of the project’s design. EDF states that incorporating a bespoke fish-protection system at this scale is a first for a nuclear power station on the estuary and will significantly reduce ecological risks associated with cooling water abstraction.

TERRATEC TBMS COMPLETE MAJOR WATER TRANSMISSION TUNNEL IN BANGKOK

Two Earth Pressure Balance (EPB) tunnel boring machines supplied by Terratec have completed excavation works on a major water transmission tunnel beneath Bangkok as part of the city’s 9th Water Supply Improvement Project. The machines were deployed on Contract G-TN-9B of the scheme, which forms part of a wider programme aimed at expanding Bangkok’s water supply infrastructure.

Launched from Shaft 9B-1, the two TBMs completed drives of 2,250m and 3,120m respectively, breaking through at Shafts 9A-5 and 9B-3. Together with a third EPB TBM previously operating on the contract, the machines contributed to the successful excavation of the 9.1km water transmission tunnel.

Challenging urban alignment

The tunnel alignment runs beneath densely developed areas of Bangkok, passing under major road corridors and incorporating several horizontal curves designed to avoid existing bridge foundations and other surface infrastructure. Excavation took place at depths ranging between approximately 27m and 34m below ground level through silty and clayey sand formations typical of the Bangkok basin. These ground conditions required careful management of face pressure and ground stability throughout the drives.

Steady advance rates maintained

Despite the restricted conditions associated with urban shaft launches and limited working space, tunnelling progress remained consistent. Average advance rates of 10 to 12 rings per day were recorded, while a peak monthly production of 429.7m was achieved during the excavation phase. Across the two drives, more than 4,500 segmental lining rings were installed and close to 90,000m³ of material excavated.

Supporting Bangkok’s water supply infrastructure

With excavation works now complete, installation of the steel liner within the tunnel is underway and is expected to be finalised within the coming months.

Once operational, the new transmission tunnel will support expanded capacity at the Mahasawat water treatment plant and strengthen the long-term resilience of Bangkok’s water supply network. Terratec has maintained a presence in Thailand for more than a decade, with the company supplying multiple machines to projects across the country, including tunnelling works for Bangkok’s Metropolitan Rapid Transit (MRT) network.

This project reflects the continued growth of underground infrastructure across the region ahead of Trenchless Asia 2026.

THE RISE OF LED AND UV LINING SYSTEMS IN TRENCHLESS REHABILITATION

As water authorities and contractors face increasing pressure to deliver faster, safer and more sustainable infrastructure rehabilitation, LED and UV-cured lining technologies are reshaping the trenchless landscape.

Driven by tighter compliance standards, growing environmental scrutiny and the need to minimise disruption, the shift from traditional curing methods to advanced light-curing systems marks a significant evolution for the drainage and wastewater sector.

At the forefront of introducing these technologies to the UK and Irish markets is S1E Ltd, a specialist supplier focused on delivering high-performance trenchless systems supported by technical expertise and industry collaboration.

Moving beyond traditional curing methods

Ambient and hot-water cured systems have long played a central role in trenchless rehabilitation. However, these approaches can involve longer curing times, higher energy demands and more complex site logistics.

LED and UV technologies offer a more controlled and efficient alternative. By enabling rapid curing with lower energy input, they allow contractors to complete installations more quickly while maintaining consistent and verifiable results.

This level of control is particularly valuable in complex or sensitive environments, including commercial sites, public infrastructure and locations where access and disruption must be carefully managed.

Advancing building and drainage rehabilitation

As the UK reseller of the BRAWO® Magnavity SX LED lining system, S1E Ltd has seen how LED curing is supporting more efficient rehabilitation of internal drainage and building pipework.

The system has been developed to cure the BRAWOLINER® range of flexible textile liners, which are designed to navigate the challenges of building drainage systems. These often include multiple bends, varying pipe diameters and restricted access points.

The lightweight and modular design of the equipment allows it to be deployed in confined environments such as basements, service ducts and internal drainage networks. At the same time, the flexibility of the liner enables it to negotiate bends of up to 90 degrees, reducing the need for invasive access or excavation.

Real-time monitoring of curing parameters provides an additional layer of quality control, supporting compliance requirements and helping ensure installation consistency.

Delivering results in live environments

The benefits of LED curing are particularly evident in live environments where downtime must be minimised.

In one recent project at a busy UK caravan park, ageing drainage infrastructure required rehabilitation without disrupting residents or site operations. The use of LED lining technology enabled works to be completed within narrow time windows, avoiding prolonged closures and reducing the need for excavation.

In another time-sensitive commercial repair, the controlled curing process and reduced set-up time allowed the contractor to reinstate the line quickly, minimising disruption while maintaining installation quality.

These examples highlight the importance of predictability and efficiency when working in operational environments.

Expanding into structural sewer rehabilitation

Alongside developments in building drainage, S1E Ltd has strengthened its offering for larger-scale pipeline rehabilitation through a partnership with SAERTEX multiCom.

The SAERTEX-LINER® MULTI system is designed for the structural rehabilitation of gravity sewers and industrial pipelines. As a UV-cured, glass fibre-reinforced liner, it offers high mechanical performance suitable for demanding applications and larger diameter assets.

The system has received approval from the Water Research Centre (WRc), a recognised benchmark within the UK water sector. This provides assurance to asset owners and contractors that installed systems meet stringent performance and durability standards.

Structural performance in practice

Recent projects have demonstrated the effectiveness of UV-cured glass-fibre liners in addressing deteriorating pipeline infrastructure.

In one UK installation, the SAERTEX-LINER® system was used to rehabilitate sections of pipeline requiring structural renewal. The liner provided the necessary strength characteristics while maintaining efficient installation processes.

Such applications highlight the role of engineered composite liners in larger-diameter and structurally demanding environments, where long-term reliability and certification are critical.

Aligning with sustainability goals

Beyond performance and efficiency, LED and UV-cured lining technologies align closely with wider sustainability objectives across the water and wastewater industry.

Trenchless rehabilitation already reduces excavation, vehicle movements and reinstatement materials. When combined with energy-efficient curing methods, the overall environmental impact is further reduced.

The adoption of light-curing systems reflects a broader shift towards improved monitoring, greater consistency and more efficient working practices across the sector.

A technology gaining momentum

As the market continues to evolve, LED and UV lining systems are moving beyond being an alternative solution.

For many contractors, they are becoming a practical, reliable and sustainable approach to trenchless rehabilitation, offering a combination of speed, control and performance that aligns with the demands of modern infrastructure delivery.

By supporting access to advanced systems for both building drainage and structural sewer applications, S1E Ltd is helping contractors adapt to changing industry requirements and deliver rehabilitation projects with greater confidence and efficiency.

RELINE Alphaliner PN sets new benchmark in pressure pipe rehabilitation performance

There is no room for compromise when it comes to pressure pipe rehabilitation. Security of supply, planning certainty, and long-term asset protection all depend on proven performance. The Alphaliner PN, developed by RELINE, has demonstrated exceptional resilience through an extensive programme of long-term and load testing – setting a new benchmark for the industry.

Extensive testing programme delivers proven reliability

From the earliest stages of development, the Alphaliner PN was subjected to rigorous testing under demanding conditions. More than 150 test liners and approximately 500 internal burst tests were conducted to refine both material performance and manufacturing processes.

In parallel, independent long-term testing was carried out by Applus+ IMA in accordance with DIN EN 1447 / ISO 7509 standards. Test specimens covered a range of wall thicknesses and diameters, including DN 300 and DN 600, ensuring robust and reliable data for real-world applications.

These results provide a solid foundation for accurate design calculations, supporting long-term operational safety and confidence for asset owners and engineers.

First liner to exceed 10,000-hour validation milestone

Industry standards require at least one test specimen to withstand 10,000 hours of hydrostatic pressure testing without failure. The Alphaliner PN not only met this requirement, it exceeded it.

One test ran for 10,815 hours with no signs of structural failure. According to Dr. Rainer Wendel, Head of Research & Development at RELINE: “The 10,000-hour benchmark allows reliable conclusions to be drawn for a service life of 50 years and we still have a safety margin.”

Following the endurance phase, pressure was increased until failure occurred. Even after this extended loading period, the liner retained 87% of its

original strength, underlining its durability and longterm performance capability.

High pressure performance across large diameters

Test results confirm that the Alphaliner PN is suitable for operating pressures of up to PN 25. Importantly, even large diameters such as DN 800 can be rehabilitated to PN 16, offering a cost-effective alternative to full pipe replacement.

The testing programme also enabled precise definition of reduction and safety factors, ensuring reliable structural design for a wide range of applications.

“The 10,000-hour benchmark allows reliable conclusions to be drawn for a service life of 50 years and we still have a safety margin

Dr. Rainer Wendel, Head of Research & Development at RELINE

Upskilling HDD crews for complex drilling projects

As horizontal directional drilling (HDD) installations become longer, deeper and technically more demanding, developing skilled and adaptable crews is increasingly important for maintaining performance and safety on site.

Training programmes that focus on planning, guidance systems, drilling fluid management and operational communication can help contractors prepare teams for more complex HDD work.

Strengthening bore planning competency

Complex HDD installations require a clear understanding of bore path design, ground conditions and potential project risks. Crews should be trained to interpret utility surveys, review geotechnical data and understand the engineering principles that influence bore profile design. When site personnel understand the reasoning behind the planned alignment, they are better equipped to maintain accuracy and respond effectively to changing ground conditions.

Advancing steering and guidance expertise

As HDD installations increase in length and depth, maintaining steering accuracy becomes increasingly important. Operators should be familiar with the use of walk-over, magnetic and gyro-based guidance systems, and understand the limitations associated with each method. Confidence in interpreting real-time tracking data allows operators to make controlled adjustments that maintain line and grade while reducing the risk of deviation.

Enhancing drilling fluid management

Drilling fluid performance plays a critical role in maintaining bore stability on complex installations. Training should include fluid selection, viscosity management, annular pressure awareness and the early identification of potential loss-of-return conditions. A structured approach to drilling fluid management supports stable bores, reduces environmental risk and improves overall installation efficiency.

Reinforcing safety and operational communication

As project complexity increases, so too does the need for clear communication between crew members.

Effective coordination between the drill operator, locator and support personnel helps maintain situational awareness and ensures that adjustments can be made safely and efficiently. Structured briefings, cross-functional training and consistent operational procedures can help strengthen on-site communication.

Continuous professional development

HDD technologies and regulatory requirements continue to evolve, making ongoing training essential. Manufacturer-led training programmes, refresher courses and on-site technical mentoring can help crews stay aligned with current industry practices and equipment capabilities. For contractors undertaking increasingly complex HDD installations, investment in workforce development is as important as investment in equipment.

STILL IN A LEAGUE OF ITS OWN

TRACTO advances zero-emission drilling with electric GRUNDODRILL JCS130E

The launch of TRACTO’s first fully electric HDD rig marks a major step toward emission-free trenchless construction

Electric construction equipment is playing an increasingly important role across the infrastructure sector, offering reduced emissions, lower noise levels and improved operational efficiency. As part of its long-term sustainability strategy, TRACTO is advancing electrification across its product portfolio, continuously adapting to technological developments and expanding its range of electric machines and components.

A key milestone in this journey is the introduction of the GRUNDODRILL JCS130E, the company’s first fully electric horizontal directional drilling (HDD) rig.

Modern diesel-powered GRUNDODRILL rigs already represent significant progress in emissions reduction. Equipped with advanced Stage V engines, they deliver substantial decreases in particulate matter and nitrogen oxides through integrated aftertreatment systems combining diesel particulate filters and catalytic converters. The result is nearzero local emissions, improved fuel efficiency and quieter operation, supporting more sustainable and comfortable working conditions on site.

Electrification for the future

While cleaner combustion technologies have improved environmental performance, TRACTO’s ambition goes further. The GRUNDODRILL JCS130E has been developed to operate entirely without local exhaust emissions, producing no diesel soot and no nitrogen oxides during operation.

In addition to environmental benefits, the electric system offers significantly higher efficiency compared to conventional combustion engines, along with reduced maintenance requirements.

“The electric system is far more efficient than the combustion engine system and requires less maintenance. We are the first to be able to offer this in the compact size of the JCS130E,” Lukas Werthmann, Development Engineer, TRACTO.

Despite its electric design, the rig delivers strong performance, with 130 kN of thrust force, 78 kW of continuous power, and up to 156 kW at peak load, demonstrating that electrification does not require compromise.

Engineering challenges and evolving technology

Developed over a three-year period, the JCS130E was first presented as a prototype at bauma 2022, forming part of TRACTO’s ‘Road to Zero Emissions’ initiative.

Integrating an electric drive system into a machine traditionally built around a diesel powertrain presented several engineering challenges. One key consideration was spatial design, as batteries, motors and inverters needed to be efficiently integrated within the existing machine architecture.

A second challenge lies in the rapid pace of development in electrical components. Unlike diesel systems, which have matured over decades, technologies such as batteries and power electronics continue to evolve quickly. This requires flexibility in design and ongoing optimisation to ensure performance, availability and future compatibility.

“

The electric system is far more efficient than the combustion engine system and requires less maintenance. We are the first to be able to offer this in the compact size of the JCS130E

Lukas Werthmann, Development Engineer, TRACTO

Infrastructure: the missing piece

Beyond the machine itself, TRACTO’s engineers identified that fully electric construction requires supporting infrastructure that is still developing in many regions.

Construction sites may not yet be equipped with sufficient grid capacity or charging facilities, meaning projects often require additional planning, grid approvals or the use of temporary solutions such as mobile battery containers.

“The demand for green construction sites is growing, particularly in European countries.

Lea Freise, Product Manager, TRACTO

However, progress is already visible in regions such as Scandinavia, where electric construction sites are becoming more established and can operate with near plug-and-play simplicity. These examples demonstrate the potential for widespread adoption as infrastructure continues to evolve.

Proven performance in the field

Despite these challenges, the GRUNDODRILL JCS130E has already demonstrated its capabilities in real-world applications across Europe.

One notable project took place in Essen, Germany, where TRACTO deployed the rig on the country’s first emission-free construction site as part of a fibre optic network expansion for GasLINE. Powered by a battery container, the system operated for approximately two weeks.

Feedback from stakeholders and local residents was overwhelmingly positive, particularly due to the reduced noise and absence of exhaust emissions.

The project highlighted not only the technical feasibility of electric trenchless construction, but also its wider benefits for communities and the environment.

“With our E-Drill, we want to respond to customer needs and meet their requirements. The demand for green construction sites is growing, particularly in European countries,” Lea Freise, Product Manager, TRACTO.

A milestone for electric trenchless technology

The GRUNDODRILL JCS130E forms part of TRACTO’s New Generation series and represents a significant step forward in the transition toward sustainable trenchless solutions. Alongside the drilling rig, TRACTO also offers the fully electrified ACS130E All Condition System, further supporting emission-free operations.

As demand for low-impact infrastructure delivery continues to grow, electric HDD technology is set to play an increasingly important role in shaping the future of trenchless construction.

Thames Water trials hydrant-entry pipe inspection using PIPA Hydrocam system

The ability to inspect pressurised water pipelines without excavation or shutdown has long presented a challenge for utilities. A recent trial within the Thames Water network highlights how hydrant-entry inspection technologies are beginning to address this gap.

Delivered by API in collaboration with PN Daly, the pilot project utilised the Hydrocam™ system developed by PIPA to assess live potable water mains under operational conditions.

Inspecting live assets without disruption

A key limitation in traditional pipeline inspection is the requirement for network shutdowns or invasive access points. Hydrant-entry systems overcome this by enabling direct access via existing fittings.

The Hydrocam™ system is designed to enter pipelines through standard fire hydrants and operate under pressure without interrupting service. This removes the need for excavation and allows utilities to assess buried infrastructure in situ. During the five-day trial, multiple pipelines of varying sizes and materials were inspected, including assets more than 80 years old.

Combining visual and acoustic intelligence

The system integrates high-definition internal imaging with acoustic sensing capabilities. An ultra-responsive hydrophone enables accurate leak detection, while the camera provides detailed visual insight into pipe condition, including lining performance and structural integrity.

Designed for use within potable water networks, the system operates within a chlorinated housing, ensuring compliance with water quality requirements while maintaining safe inspection conditions.

Trial outcomes and operational insight

The trial delivered a range of practical outcomes across the inspected network. Multiple leaks were identified and marked at ground level, while several hydrants were found to be faulty or non-operational. The system also enabled identification of pipe condition issues and lining failures.

In one case, a suspected leak identified using correlator equipment was confirmed to be a non-leak following inspection, demonstrating the value of direct internal assessment in validating field data.

All findings were compiled into detailed reports to support ongoing asset management and future intervention planning.

Supporting proactive network management

Hydrant-entry inspection technologies are increasingly supporting a shift towards proactive, data-led management of water infrastructure. By enabling detailed condition assessment without service disruption, utilities can better prioritise maintenance, rehabilitation and replacement programmes.

The technology can be used to investigate water quality issues, identify illegal connections and assess network performance, while also providing valuable data ahead of cleaning, lining or renewal works.

Scaling inspection across networks

The flexibility of hydrant-entry systems allows deployment across a wide range of network configurations. Systems can be introduced via hydrants, valves and other pressure fittings, and can be adapted to travel through pipelines using different methods depending on site conditions.

Further developments are focusing on extending inspection range for trunk mains, enabling utilities to assess larger sections of network infrastructure in a single deployment.

A shift in inspection strategy

As water networks continue to age and regulatory pressure increases, the need for accurate, non-invasive inspection is becoming more critical.

Hydrant-entry inspection represents a shift towards targeted, evidence-based intervention, allowing utilities to better understand asset condition while maintaining service continuity. For the trenchless sector, this reinforces the growing importance of inspection technologies as a key part of the rehabilitation and asset management lifecycle.

The anatomy of an Audit

Frank Reilly Director JBP’s Trenchless, Training Programme

Last month I looked at why skills audits matter. Trenchless technologies and methods continuing to change quickly across the sector and expectations of performance keep rising. Relying on assumptions about workforce capability is no longer enough. The question for organisations is not whether to audit skills, it is how to do it effectively.

Done properly, a well-designed audit becomes one of the most practical tools, to strengthen operational performance. So, let’s take a closer look at the anatomy of an audit.

Breaking capability into real competencies

The starting point of any audit is simple: define what capability actually looks like.

In the water and wastewater infrastructure sectors this typically spans areas such as inspection and coding, rehabilitation technologies, equipment operation, project supervision, and health and safety compliance. But broad categories are not enough. Each area needs to be broken down into specific competencies.

Take CCTV inspection as an example. Competence does not sit in a single skill but in several: equipment setup,

defect recognition, coding accuracy, reporting quality, and data interpretation. By separating capability into defined components, organisations begin to see where genuine expertise exists, and where it does not.

Mapping the workforce

Once competencies are defined, the next step is to map them across the workforce. This is where the audit often reveals some uncomfortable truths.

In many companies, certain skills are concentrated in just one or two individuals. In others, training may have been completed years ago with little follow-up or reassessment. Some teams may appear well trained on paper but lack practical field experience.

An audit’s purpose is not to criticise individuals. It is to understand the organisation’s technical resilience. If a key technician leaves tomorrow, can the company still deliver the same level of service?

Evidence, not assumptions

Meaningful audits rely on evidence. Certificates, training records, project experience, and practical assessments all contribute to the picture.

At the same time, the process often uncovers something valuable: informal expertise. Many experienced technicians possess deep operational knowledge that may never have been formally recognised or documented. A good audit captures that knowledge and integrates it into the organisation’s competence framework and highlights where certificates alone are not enough to guarantee real operational confidence.

Turning insight into action

Identifying gaps is only the first step. The real benefit of an audit comes when organisations translate the results into targeted development, building focused training pathways that address specific capability gaps. Training budgets become strategic investments rather than routine expenditure. This shift is critical.

A foundation for future capability

Ultimately, a skills audit provides something many organisations lack: visibility.

Trenchless technologies will continue to evolve, water and wastewater infrastructure challenges will continue to increase, and performance expectations will continue to rise. Those organisations that understand their capabilities, and act on that knowledge, will be the ones best prepared for what comes next.

No-Dig Roadshow Dublin highlights major trenchless infrastructure projects

Ahigh-quality conference programme and busy exhibition floor made the latest No-Dig Roadshow in Dublin a standout industry event, with major project updates from Uisce Éireann and Northern Ireland Water showcasing the growing role of trenchless technology in delivering critical water and wastewater infrastructure.

The latest No-Dig Roadshow, organised by Westrade and supported by the UK Society for Trenchless Technology (UKSTT), proved a major success when it arrived at the Castleknock Hotel in Dublin, bringing together contractors, engineers, water utilities and technology providers for a day dedicated to the latest developments in trenchless technology.

With a strong turnout of industry professionals, the event combined a high-quality technical conference with a vibrant exhibition floor, providing delegates with valuable insights into major water and wastewater infrastructure projects currently being delivered across Ireland and Northern Ireland.

Major infrastructure updates take centre stage

A key highlight of the conference programme was a comprehensive update on the Greater Dublin Drainage (GDD) Project, presented by representatives from Uisce Éireann. Dermot Bruton, Programme Manager, Strategic

Projects, and Jonathon Edgeworth, Programme Manager, Strategic Projects, provided delegates with an in-depth overview of the project, outlining programme timelines, anticipated pipeline requirements, indicative ground conditions along the proposed route and the scope of the various work packages.

Delegates also heard that the project has now received full approval to progress to the construction phase, marking a significant milestone for the strategic scheme. Pre-construction works are currently out to tender, while the main construction package is moving through a prequalification process that will identify four contractors to bid for the works later this year.

The speakers highlighted the scale and importance of the project, which will provide long-term wastewater capacity for the Greater Dublin area. With significant pipeline infrastructure required across complex ground conditions and sensitive urban environments, trenchless construction methods are expected to play a key role in delivering elements of the scheme while minimising disruption.

Another standout presentation came from Northern Ireland Water, which provided an insightful case study on the Meadow Lane Portadown Wastewater Pumping Station (WWPS) project.

Presented by John Griffin, Head of Wastewater Capital Delivery (Infrastructure) at Northern Ireland Water, alongside Conor Ward of BSG Civil Engineering, the session examined the successful trenchless installation of a 1500mm diameter tank sewer as part of the scheme.

The speakers highlighted how early contractor involvement played a crucial role in the success of the project, allowing the delivery team to collaborate on the most effective construction methodology from the outset. The use of a tunnel boring machine (TBM) enabled the sewer installation to be completed with minimal surface disruption, significantly reducing the impact of the works on the surrounding area during construction.

Beyond the engineering achievement, the project is delivering important long-term benefits for the local community. The new infrastructure will help improve environmental performance by reducing the risk of flooding while increasing wastewater network capacity to support future development and economic growth in the Portadown area.

Membership buzz update

By Tim Sargent

We are delighted to give you an update on the recruitment of new members since the start of the year, this has been one of our best starts to any year to date with 5 including the following companies, Bethell Construction, F M Conway, HY-RAM Engineering Co Ltd, Pro Lining Solutions and Saertex.

We continue to make progress to being able to make our society resilient through having a diverse membership. This must remain one of our key strategic goals for us at UKSTT, creating value across a broad range of companies and individuals withing them.

With respect to our Patrons members which includes major network asset owners such as Thames Water, Scottish Water, Cadent and Scotia Gas Networks, this remains a unique aspect of our membership community and therefore we are continuing to look for new ways to engage and bring them closer to us.

One idea being considered is how we might improve alignment between council members and the Patrons themselves, to develop deeper existing relationships. We want to encourage Patrons’ participation with UKSTT across multiple events and through multiple contacts. We will be reviewing this potential approach at the next council meeting in April.

Areas of focus should be for Patrons to engage and be active participants in events such as our MasterClasses, No- Dig Roadshows and this year No Dig Live 2026. We would encourage all of you, as existing company members, to foster your Patron relationships with networks and likewise encourage them to attend and support our events and those of Westrade, our event partner.

Recent examples of Patron engagement have included as at our conference in March, Wessex Water speaking, through their Engineering Director, Eddie Rant, and also having a large contingent of attendees from Severn Trent Water’s capital delivery team. Separate to this, Iain Nailsmith and I will be supporting United Utilities at their Innovation Day which we are helping deliver, focused exclusively on trenchless technology at the end of March.

With regards to our academic partners, Birmingham & Sheffield, although very engaged, they are still not formally signed up under this new membership category, we will all be seeking to get them on board shortly!

We have for some time being developing a new category for the large drainage franchises such as Metro Rod and are exploring with these groups how best this could be achieved.

A new associate membership will be launched soon, to attract more third-party stakeholders, such as councils, designers and environmental bodies, we’ll keep you updated on progress. Also given the great success of our New to Trenchless webinars and events, we will explore whether a category for this type of membership might be of value.

As always, our door is open, and do reach out to me, and all of us at UKSTT, your society, if you have thoughts and ideas to support membership engagement and participation, it’s your society, so make the most of what it can offer you and your companies through active membership.

Walking the Inca Trail

In early May Jo Parker, former council member and UKSTT Trenchless Woman of the Year will be attempting to trek the Inca trail. This is a 26 mile path crossing the High Andes starting at 2,200m high at Cisco and at time reaching over 4000m high. The trek will take 4 days and she will be camping. Over that time there will be no electricity and no communications.

Jo is not and never has been an avid walker – or any sort of walker at all. With flat feet, scoliosis (a spinal curve) and dodgy hips, walking, especially uphill, is painful. A series of respiratory diseases including Bronchitis, Covid and Whooping Cough in 2024 leaves her wondering how she’ll cope with the altitude. However, the views will be wonderful and a lifelong desire to visit the end point of Machu Pichu, she hopes, will keep her going. Her training mostly consists of

walking into the centre of town to do the shopping and walking back with a full rucksack!

When she asked the organisers what’s the age of the oldest person to do the trek, they thought they were reassuring her when they said that ‘quite a few had done it in their 60s’. She will be 72!

She is doing it in memory of a good friend, Matt Hake, who succumbed to cancer just before Christmas. He spent his last days in Keech Hospice and she’s collecting money for them.

If anyone does want to support her efforts, they can donate via her Just Giving page https://www.justgiving.com/page/jo-parker-5

ISTT webinar to explore condition assessment of large-diameter sewers

The International Society for Trenchless Technology (ISTT) will host an upcoming educational webinar on 21 May 2026, focusing on advanced approaches to condition assessment for large-diameter sewers and wastewater structures.

Open to both members and non-members, the session will provide valuable technical insight for engineers, asset owners and infrastructure professionals. Recordings will be available exclusively to ISTT members.

Engineering-based approach to structural evaluation

Titled “Engineering-Based Condition Assessment of Large-Diameter Sewers and Wastewater Structures for Structural Capacity Evaluation”, the webinar will be delivered by Dr.-Ing. Robert Stein of Stein & Partner GmbH, Germany.

The session will examine how the assessment of large-diameter sewer systems differs significantly from standard pipeline inspection. Unlike factorymanufactured pipes, these structures are often bespoke civil engineering assets, constructed decades ago with limited documentation and variable materials.

As a result, traditional inspection techniques alone are often insufficient to determine structural integrity. The webinar will present a more advanced, engineering-

led methodology that integrates inspection data with structural analysis to deliver a more accurate understanding of asset condition.

From inspection data to actionable insight

The approach outlined in the webinar demonstrates how extended condition data can be combined with engineering modelling to reconstruct structural behaviour and evaluate remaining load-bearing capacity.

This enables infrastructure owners to make more informed decisions, supporting targeted and cost-effective rehabilitation strategies while reducing the risk of both over-design and structural failure.

The session will also highlight how condition assessment can move beyond visual inspection to become a key tool in long-term asset management and sustainability planning.

Event details

The webinar will take place on 21 May 2026 at 14:00 GMT (16:00 CET / 10:00 EST).

Registration is now open via the ISTT website: https://istt.com/announcements/webinar_20260521

Attendance is open to all, with on-demand access available to ISTT members following the event.

Dr.-Ing. Robert Stein is Managing Associate of

He has extensive experience in major utility tunnelling projects, including the 52 km Emscher Kanal wastewater system in Germany, where he was responsible for approval processes, planning, supervision and quality control.
