Based On The Night Flow Monitored Of District Metered Area Management

As the important infrastructure in the process of city development, water supply network, of which the stand or fall of running status is closely linked with whether the city could run normally. But by itself or outside factors, water supply network leakage is inevitable. Due to affecting users’normal water consumption and wasting the water resources which is already limited, the existence of leakage has been an important daily management work of water supply department. Therefore water supply network leakage control and management not only protect the water resources but also a requirement of enterprises to improve management level. So we should from technology and management do both to form the system leakage management control strategy.In recent years, DMA (District Metered Area, referred to as the DMA) especially for real losses, is one of the most popular methods of water supply network leakage, On the premise of safe water supply, the method using the valve, flow meter, etc divide pipe network into separate areas, through the different parts of the nighttime traffic analysis, to estimate the leakage situation of water supply network, then take the corresponding leakage control measures.Based on the physical losses control of the DMA management as the key point, the article elaborates the design criteria, the steps how to build and validation methods of the DMA. Then, the article on the basis of one residential area of the city of ZZ, from which at the same time collect data and sort it, finally using the Lossaving to monitored warning, burst alarm. In addition, the essay discussed the relationship of the real losses and the Non-revenue in detail, emphatically pointed out that physical losses is not the only factor for the NRW of the water supply network.For commercial losses, the article lay on the theory for the analysis of commercial losses, at the same time, according to the practical production data from the different typical meters of the KY city in domestic.The article argument the real losses and commercial losses separately, and lay on the practical production data, can be used as a water supply industry management and control of leakage of base case.
