- Abstract:
- The new industry standard was compared at home and abroad in the aspects of metering statistical range, water balance components and water loss rate. The water loss control practices in Beijing mainly includes analyzing water loss and controlling key points through water balance factors, selecting district metering area (DMA) practically, optimizing water pressure through adjusting the regulations of pumps and valves based on GIS system and hydraulic models, gradually replacing 1.46 million smart water meters, developing water consumption remote monitoring and analysis system, and reducing the breaks in pipes through active leak detection and pipe rehabilitation. The above measures resulted in a consecutive reduction of water loss rate in downtown Beijing for ten years, reaching 9.93% in 2020.
