Core Viewpoint - The city of Zhenjiang is initiating a significant renovation of its aging water supply infrastructure, aiming to enhance water quality, pressure stability, and safety for residents by 2027 [1][4]. Group 1: Current Issues - As of 2023, Zhenjiang has approximately 2398 kilometers of water supply pipelines, with many exceeding 30 years in operation, posing substantial safety risks [2]. - The older pipelines, primarily made of gray cast iron and prestressed concrete, are prone to damage from temperature fluctuations and ground subsidence, potentially leading to widespread water outages and secondary disasters [2]. - Aging infrastructure results in poor water quality and pressure, with corrosion and scaling in older pipes increasing flow resistance and causing instability for high-rise users [2]. - Significant water resource wastage occurs due to leaks and ruptures in older cement pipes, which have been in use for over 30 years [2]. Group 2: Engineering Progress - The renovation project will update 21.64 kilometers of municipal water supply pipelines and replace the risers in approximately 10,500 residential units across three districts [3]. - The first phase of the project has commenced in several neighborhoods, including the Danxiang Garden, with construction starting on September 25 and municipal pipeline work beginning on September 30 [3]. - The project will utilize corrosion-resistant and high-strength materials, such as ductile iron pipes, to ensure the long-term safety and stability of the water supply network [3]. Group 3: Social Impact - The large-scale renovation is crucial for ensuring the safe operation of the city and enhancing urban resilience, significantly improving water quality and pressure for residents [4]. - The project is expected to reduce pipeline leakage rates, conserving water resources and alleviating operational pressures on water supply companies, thus achieving both economic and social benefits [4]. - The implementation of this project will enhance residents' quality of life and contribute positively to Zhenjiang's sustainable development and "ecological garden city" initiatives [4].
