Non-revenue water

The challenges facing water utilities

Within discussions centered around sustainability, water scarcity, and the conservation of precious resources, one topic regularly covered is how utilities can better solve the challenge of water loss within their network. The need to protect precious resources and reduce water loss to more acceptable levels has made non-revenue water (NRW) one of the most challenging problems for water utility owners and operators to overcome.

Non-revenue water is the difference between the water entering a distribution system and the amount billed to water consumers. NRW is not the only actual loss of water, such as leakage or pipe bursts, but it also can impact all levels – from water abstraction to billing. Causes are as diverse as they are complicated to identify and measure, making NRW a major topic to ensure the future of resilient utilities.
