Case Study on Solutions of Urban Water Supply Leakage Control in North China Plain Cities
The shortage of water resources is a common problem in North China Plain cities,which has become an important factor restricting urban development.Leakage control of urban public water supply network is an important part of urban water conservation.This study took City A as an example to carry out a case study of urban water supply leakage control strategy in North China Plain,proposed a set of leakage control target formulation methods based on water supply balance analysis and leakage control potential prediction,and developed a set of leakage control system scheme in combination with the characteristics of the urban water supply system in North China Plain,and focused on introducing the zoning metering management construction and operation and maintenance scheme of City A.The research results showed that cities in the North China Plain could carry out the leakage control of urban public water supply pipe network from six aspects:finding out the family background,updating facilities,regulating pressure,improving measurement,introducing intelligence and enabling,and improving the mechanism.For cities with small area pipe network leakage as the main factor,the bottom-up district meter areas construction route should be adopted,and the zoning measurement platform should be improved,the management system established,and the workflow standardized.Research can provide guidance for similar cities to carry out urban public water supply network leakage control work.
