Non-Revenue Water

Non-revenue water (NRW) is increasingly recognized as more than an operational challenge — it is a direct reflection of how effectively a utility understands, manages, and maintains its distribution network. While water loss has historically been treated as an unavoidable cost of doing business, growing financial pressures, aging infrastructure, workforce limitations, and rising customer expectations are forcing utilities to rethink that assumption.

Today, progressive utilities are shifting from reactive leak management toward proactive NRW control strategies built around data, visibility, and measurable performance improvement. Water loss is rarely sudden or unpredictable. In most cases, it develops progressively over time, making it increasingly detectable and preventable through modern monitoring technologies, advanced analytics, and improved operational practices.

This e-book explores the evolving approach to NRW management through six articles focused on economics, technology adoption, system performance measurement, and organizational culture. Together, these perspectives highlight how utilities are moving beyond simply tracking loss percentages toward developing a deeper understanding of network behavior and asset performance.

The articles also examine how improved NRW management supports broader utility objectives, including extending infrastructure life, improving service reliability, protecting affordability, strengthening sustainability efforts, and maintaining public confidence. From leak detection and pressure management to operational decision-making and long-term planning, the industry is redefining what effective water loss control looks like.

Reducing NRW is no longer viewed as an aspirational goal reserved for large utilities — it is becoming a measurable, achievable strategy for utilities seeking greater operational resilience and long-term system performance.
