Practice and Study of the Effect of One-Household-One-Meter Conversion on NRW

Abstract:

In order to test the effect on NRW(None Revenue Water) of one-household-one-meter conversion, find out key factors to influence the water supply efficiency and propose ways to reduce the rate of NRW, this article was based on the current practical engineering situation in Chongqing, China, by selecting 5 representative controlled fields for a six-month testing period. It shows that: different installation qualities of one-household-one-meter act different influences on NRW. The individual customer’s domestic water can be measured effectively by installing the drip-proof valve. The rate of NRW can be decreased at the beginning in the fields with “drip-proof valve + meter”. Water supply efficiency rate of the fields with “meter only” keep stable during 6 months, and meanwhile the fields with “drip-proof valve + meter” decrease over time. The function of drip-proof valve is found to stop at 147 days after installation due to the rust and sand getting into the valve. “Drip-proof valve + meter” is a practical and effective one-household-one-meter conversion method. Relevant standard atlas is recommended to be developed and implemented timely. Maintenance of pipeline and guarantee of water quality in pipeline are very important to keep the contribution of “drip-proof valve + meter” on NRW.
