To provide water utilities operating under rationing conditions with some insight into issues related to managing non‐revenue water (NRW).
Reviews general theories associated with pressure, surges and water leakage, and compares them with real data in a rationed water distribution system.
In water networks there is a strong relationship between rationing hours and rationing surge pressures and NRW levels. These relationships mean that traditional ways of benchmarking NRW are not useful in rationed systems.
This paper identifies key NRW issues for utilities operating under rationing and gives them help in identifying options for their NRW strategies.
