Non-Revenue Water (NRW) is the volume of water supplied into the network but is lost or unaccounted for before getting to the consumers resulting in loss of revenue for water utilities. Most water utilities in Zimbabwe record more than 60% NRW and the need to reduce it cannot be over emphasized. Reducing these water losses is critical for efficient resource utilization, efficient utility management, enhanced consumer satisfaction, and consideration of capital-intensive projects meant to augment water supply capacity. The costs of improved service delivery are much lower when non-revenue water reduction is prioritised. It is against this background that Institute of Water and Sanitation Development (IWSD) has moved in to support all water utilities through a training workshop to dentify and interrogate the foundations of NRW in order to come up with practical management systems to mitigate against heavy financial and social loses that are currently being experienced.
