Curbing Asia's Nonrevenue Water

Publication | August 2007

This brief discusses how utilities can stop water losses and therefore increase revenue.

Utilities in Asia particularly have every reason to worry about water losses - they lose up to 65% of their production daily, with most utilities averaging a 30% loss. This bane of every water utility’s existence is called nonrevenue water (NRW).

NRW is water that does not bring revenue for the utility as it should. There are three reasons:

  • water is distributed but never arrives at the tap because of leaks, bursts, or overflows;
  • water is used without the utility’s consent, mainly through theft and illegal connections, or improper metering; and
  • water used for free with the utility’s permission, e.g., free water distributed at standpipes or used for cleaning reservoirs or fighting fires.
