With the development of the economy and society,the process of urbanization is accelerated.The contradiction between water resource supply and demand is becoming increasingly serious.The leakage of water supply pipelines network is one of the problems of water saving.The leakage control of water supply pipelines networks has become one of the key tasks of urban water supply industry in the 14th Five-Year.This paper briefly introduces the causes and main control methods of water supply pipelines network leakage.Focusing on analyzing the actual engineering application effectiveness based on the characteristics of the water supply company itself,mainly including:monitoring the minimum flow at night by constructing on district metered area(DMA);carrying out daily inspection and periodic leakage detection;regular water meter rotation;reconstructing old pipelines network;setting up pressure monitoring points and adding remote monitoring of water tank.By combining various control methods,the water supply pipelines networks leakage has been effectively controlled and the comprehensive leakage rate of 2023 has been reduced to 10%.The research results are expected to provide guidance and reference for the leakage control of the water supply pipelines network of various water supply companies.
