Scope

With the acceleration of urbanization, urban water supply networks, as an important component of urban infrastructure, play an indispensable role in ensuring residents' daily life and industrial production, promoting economic development, and maintaining social stability through their safe, efficient, and sustainable operation. However, for a long time, urban water supply networks have generally faced prominent problems such as high leakage rates, high energy consumption, and difficult management during operation, which not only result in significant waste of water resources but also impose a heavy economic burden on water supply units. Therefore, how to scientifically and effectively control leakage in urban water supply networks and improve water supply efficiency and management level has become an urgent major issue to be addressed at present. As an advanced leakage control method for water supply networks, zoning metering leakage control technology has received extensive research and application at home and abroad in recent years. This technology realizes rapid response and effective control of network leakage by scientifically and reasonably dividing the water supply network into zones and installing monitoring equipment for flow, pressure, and water quality to monitor the water supply and leakage situation in each metering zone in real time. This technology not only significantly reduces network leakage rates and reduces water waste, but also improves water supply efficiency and service quality, bringing significant economic and social benefits to water supply units. However, despite the significant theoretical advantages of zoning metering leakage control technology, it still faces many challenges and difficulties in practical application. Firstly, how to scientifically and reasonably divide metering zones according to the characteristics and actual situation of urban water supply networks is the prerequisite and foundation for implementing this technology.
