Non-revenue water loss in Norton, Zimbabwe: Levels, Sources and mitigatory measures


Tanyaradzwa Chigonda, Evans Chazireni

Understanding elements of non-revenue water loss has become more crucial in an era where urban water demand, particularly in developing countries, is rapidly increasing. Non-revenue water is the difference between the amount of treated water put into the distribution system and the amount of water billed to consumers. The study sought to establish the levels and sources of non-revenue water loss in Norton between 2010 and 2014. The study revealed an unacceptably high average annual non-revenue water loss of 40% in Norton during the period under review. Various sources of non-revenue water loss including pipe bursts, metering inaccuracies, authorized unmetered use and unauthorized unmetered use were identified. The study recommends that Norton Town Council should install computerized leak detection for quick response to pipe bursts in the reticulation network. Norton Town Council should also ensure that all water consumption in the town is accurately billed through properly functioning water meters.
