As the Zhuguantun water source is located in the Zhuohuai Basin on the north bank within the first terrace of the Yangtze River, the shallow water quality is unstable, the study of deep water is limited, and the hydrogeological conditions are complex. Based on national and local regulations, policies, and planning, the reasonableness of updating the existing water source wells, the guaranteed level of water withdrawal, the reasonableness of project water use, and the water saving potential of the project are fully demonstrated, and scientific, objective, and fair conclusions are given to provide a reliable technical basis for the management of water supply permits for construction projects.
