Abstract - Non-Revenue Water (NRW) represents a significant challenge for urban water utilities, resulting in financiallosses,reducedwateravailability,andinefficiencies inwaterdistribution.Thisproject,titled"EnhancingWater Utility Efficiency: Using Bulk & Domestic Water Meters to ReduceNon-RevenueWaterinCityWaterSupplyNetworks fromSourcetoConsumer,"aimstoaddresstheseissuesby implementinganintegratedmeteringapproach.Theproject explorestheuseofbulk watermetersatkeypointsinthe water distribution network, such as treatment plants, reservoirs, and distribution mains, to monitor large-scale waterflowsanddetectsystem-widelosses.Attheconsumer level, domestic water meters provide accurate data on individual consumption, enabling utilities to identify unauthorized usage, address billing discrepancies, and promoteresponsiblewateruse.
Throughreal-timedatacollectionandanalysis,theproposed metering system allows for proactive leak detection, targetedmaintenance,andbetteroverallmanagementofthe water distribution network. By integrating bulk and domestic metering with GIS and SCADA technologies, the projectaimstocreatearobustdatamanagementframework thatenhancesutilitydecision-making,minimizesoperational losses,andimprovesrevenuecollection.Thiscomprehensive approach not only reduces NRW but also strengthens the financialsustainabilityofwaterutilities,ensuresfairbilling, andsupportssustainablewaterresourcemanagement.The project’s findings contribute to a scalable NRW reduction model that can be adapted across various urban settings, pavingthewayformoreresilientandefficientwatersupply systems.

EnhanceutilityefficiencyusingGISandSCADAtechnologies. Promote financial sustainability and equitable billing practices.
2.2 Scope:
This study integrates advanced technologies and public engagement to reduce NRW, focusing on operational improvements, data-driven decision-making, and scalable frameworksadaptabletoothercities.

Despite sufficient water production, inefficiencies in the network result in high levels of wastage. Additionally, intermittent supply practices lead to pressure fluctuations, further contributingtolosses.

3.4 Service Level Benchmarks (SLB) for Water supply
Astandardizedsetofkeyperformanceindicatorsrelatedto urban management and service delivery were defined, measuredandbeingreportedonacrossurbanareasbyULBs and other city-level parastatals. The standardization is ensured by setting definitions and units along with data requirements and reliability of measurements (MoHUA, 2009).
ThewaterrelatedServiceLevelBenchmarks(SLBs)focuson extentandaccessibilitytoqualityservicewhileconsidering effectiveness of the system to manage the water supply network including aspects of financial sustainability. The following are the indicators for water services which includestheextentofNRW.

As per the SLB Handbook, the rationale for introducing ‘Extent of NRW’ indicator is to assess the financial sustainabilityofthewaterutilitybyreducinglosseswhich can be utilized to meet excess demand and defer capitalintensive expenditure to enhance supply capacity. The benchmarkvalueforNRWis20%whichhasbeenachieved by most well-performing utilities in developed countries (MoHUA,2009).
