The water supply network in old urban areas suffers from issues such as aging pipes, high leakage rates, and water quality safety hazards. There is an urgent need for systematic renovation to ensure residents' water safety and promote sustainable urban development. This paper focuses on strategies for renovating the old water supply network, combining engineering practices to propose a phased and zoned update plan. It also introduces intelligent monitoring technology to enhance network management. Through a comprehensive evaluation of economic and social benefits, the rationality and feasibility of the renovation project are verified, highlighting its significant role in reducing leakage rates, improving water supply reliability, and conserving water resources. This provides a scientific basis for upgrading urban infrastructure.
