The present disclosure belongs to the field of municipal engineering and urban water supply network, and provides an efficient method for localizing leaks in a districted metering area (DMA) of water supply pipe networks based on valve operations and online water metering, which is implemented in multiple stages to gradually reduce the leaking area. At each stage, the DMA is firstly decomposed into two sub-areas using an optimized valve operation strategy determined by a minimized objective function, wherein a graph theory-based method is used for the solution. Then the sub-areas containing leaks are identified through online water balance analysis based on smart demand meters, thereby reducing the leaking area. The minimum leaking area is identified with the least number of valve operations. Compared with the traditional methods, the method of the present disclosure can obviously improve the efficiency and accuracy of leak localization and is easy to implement.
