Application of DMA Technology in a Community Water Leakage Management
DMA technology has become one of the important means for many large and medium-sized urban water companies to reduce water supply network leakage.Taking the analysis and control of leakage in a certain residential area as an example,this article introduced the experience of DMA technology in water supply network leakage control.Practice had proven that after establishing DMA in a residential area,physical leakage could be effectively identified by real-time monitoring of the minimum night flow in the community.By establishing a secondary DMA in the community,it was possible to effectively identify possible physical water leakage in the household table,thereby further accurately locating and repairing the leakage points,and reducing the water leakage in the water supply network of the water company.
