A » Non-revenue water (NRW) refers to water that is produced but not billed to customers, including losses from leaks, theft, or meter inaccuracies. It is calculated as the difference between the volume of water supplied to the distribution system and the volume of water billed to customers. NRW percentage is determined by dividing the volume of NRW by the total volume of water supplied, then multiplying by 100.
