The western route project is in a relatively stable area and the construction technology of dam and long deep tunnel is feasible. This project is economically reasonable, with 11.8% economic internal rate of return, 108.395 billion Yuan economic net present value, and 1.7 economic benefits cost ratio. In addition to the quantitative calculation of the benefits of the project, there are more important social and environmental benefits. The project promotes the economic and social development of Yellow River Basin and the Northwestern area. This project enlarges the water supply of Yellow River and alleviates substantially the contradiction between supply and demand of the Yellow River water resources, and further protects and improves the ecological environment. The effects of this project on the intake areas include: 1) the range of the water supply is extensive; 2) maintain the ecological development of Yellow River; 3) improve the ecological environment of the intake areas; 4) maintain the ecological safety of China. The project’s positive effects on the society and economy of the water supply areas include: 1) bring economic opportunities for the water supply areas; 2) promote the upgrading of local economic structure; 3) promote the urbanization of water supply areas; 4) improve local citizens’ scientific and cultural quality. The project’s negative effects on the society and economy of water supply areas include: 1) the adverse impact on farming industry of water supply areas; 2) the adverse impact on migrates and religious facilities; 3) the adverse impact on the development of hydroelectric resources of downstream areas.
