Based on the introduction of the present status of rural drinking water project in Changge City and the “Twelfth Five-Year Plan”, the article elaborates on the necessity, rationality and safety of rural drinking water access to groundwater. Based on the analysis and calculation of the groundwater resources in the middle and deep layers of Changge City, the distribution law of groundwater resources in Changge City is revealed and the quality of groundwater is evaluated. Combined with the quantitative analysis of rural domestic water use, the water quality and water quantity are determined to meet the current water supply and water supply requirements. At the same time, a reasonable analysis of water diversion and wastewater reclamation was carried out, and the quantitative indexes for the reasonable exploitation of deep groundwater and the concrete measures needed to be taken to protect the groundwater were given.
