Ningjin County is located in northwest Shandong Province in the North China Plain. The water shortage can be solved if the South-to-North Water Transfer Project is completed, but the project water price is higher than the price of local groundwater and Yellow River water, so it is urgent to make the comprehensive water price of multi-water resources in this area. The water demand of non-agricultural water users in the planning year of 2020 and 2025 is forecasted based on water supply and consumption in current year of 2017, and two water supply schemes are set up respectively, four schemes totally considering the factors whether Yangtze River water will be obtained. The water prices of four schemes are calculated using weighted average model. The results show that when the transferring water replaces partial underground water in 2020, the comprehensive water prices of scheme 1 and scheme 2 are 3.21 yuan/m 3 and 2.11 yuan/m 3 respectively. When the transferring water replaces all groundwater in 2025, the comprehensive water prices of scheme 3 and scheme 4 are 2.92 yuan/m 3 and 1.44 yuan/m 3 respectively. The compensation mechanism of water price is discussed finally.
