NRW Interventions to Reduce Water Losses

The IWA Utility NRW Assessment Matrix is a valuable self-assessment tool designed to help water utilities identify areas for improvement in managing Non-Revenue Water (NRW). It evaluates six key areas: Water Balance, Leak Repair, Key Performance Indicators, Active Leakage Control, Customer Metering, and Managerial Commitment. Each area is assessed using a rating scale from 1 (poor) to 5 (excellent), with specific descriptions provided for each level. This structured approach enables utilities to diagnose weaknesses, track progress, and implement targeted strategies to enhance overall water efficiency and reduce losses.
