合肥城市供水水源主要是巢湖和蕙铺水库。巢湖的取水量占 70 % ,但水质污染日超严重 ,已不适合作为合肥市的主要生活饮用水源 ,为了扩大水源 ,充分利用　铺水库通过　史杭灌渠与上游三大水加相通、水量交沛、水南优良的有利条件 ,合肥市将供水项目纳入　史杭灌区的供水规划之中 Hefei’s urban water supply sources are mainly Chaohu Lake and Puye Reservoir. Chaohu Lake takes up 70% of the water, but the water pollution day is very serious. It is not suitable as the main source of drinking water in Hefei. In order to expand the water source, it makes full use of the reservoir to pass through the Shihang irrigation canal and the three upstream waters to increase the access and water flow. Pei and Shuinan have favorable conditions. Hefei will integrate water supply projects into the water supply plan of Shihang Irrigation District.
