Achieved results, underlying approaches and contributing factors to success of 8 Non-Revenue Water (NRW) reduction interventions (2012-2019) of 19 water operators from Asia and Africa are presented in this Practice Note.
The document builds on the joint review commissioned by the Netherlands Enterprise Agency (RVO) and executed by VEI. Its conclusions and recommendations can assist practitioners in designing and implementing future NRW programmes.
To assess the up-scaling potential, reduced NRW volumes in District Metered Areas (covering 435,000 connections) were translated to cost savings and revenue increments (based on the established commercial/physical losses ratio) to evaluate the business case.
The Practice Note also evaluates the extent in which NRW-reduction can effectively contribute to improving service delivery to the urban poor.
