Non-Revenue Water

Across South Africa’s economic heartland of Gauteng, water supply has become a recurring public concern. From unplanned outages to pressure fluctuations and repair-induced disruptions, metropolitan water networks face growing operational challenges. Recent reporting suggests these issues are not isolated incidents, but signs of wider strain on urban water infrastructure.

Smart water metering helps municipalities reduce water loss through accurate measurement, remote monitoring, and early leak detection.

Non-revenue water (NRW) remains one of the most critical challenges facing water utilities worldwide. It represents water that is produced and treated but never billed due to losses, inaccuracies, or unauthorized consumption. For municipalities and utilities, high levels of non-revenue water directly translate into lost revenue, increased operating costs, and unnecessary strain on already limited water resources. Understanding the causes of non-revenue water is the first step toward reducing it.
