The Hidden Cost: Uncovering The Truth About Non-Revenue Water

Non-revenue water (NRW)—the difference between water produced and water billed—remains one of the most overlooked challenges in water management. Whether through physical losses, meter inaccuracies, unauthorized consumption, or unbilled authorized use, NRW erodes revenues, drives up costs, and undermines public trust. While historically downplayed, the urgency to address NRW is growing with rising water scarcity, inflation, and infrastructure pressures. Utilities can make significant progress by first performing comprehensive water audits to identify losses and prioritize interventions. Upgrading aging meters to ultrasonic technologies with embedded acoustic leak detection provides highly accurate, long-term measurement while enabling continuous leak monitoring throughout distribution networks. Complementing these with strategically placed pressure sensors delivers broader system insight at lower cost. Paired with advanced metering infrastructure (AMI), utilities can achieve daily systemwide leak detection audits. Quick wins, such as fixing visible leaks and faulty hydrants, combined with community outreach, further strengthen results. By embracing proactive NRW management, utilities can protect resources, stabilize finances, and deliver more resilient water services.
