The West-Route of the South to North Water Transfer Project is an ponent of national four transverse and three lengthways water resources allocation pattern , plays an important role in reducing the conflict between water supply and demand and ensuring the water supply security . The necessity from inter-basin water transfer to the Yellow River was discussed by several aspects , such as reducing the conflict between water supply and demand , maintaining river health , and improving the ecological environment etc ., the characteristics of the water diversion schemes , as well as the advantages of the first stage of the West-Route Project was analyzed , then the
