How many lines are there in the South-to-North Water Transfer Project? Who are they?

The South-to-North Water Diversion Project has three lines, which are divided into east line, middle line and west line. The starting point of the East Line Project is located in Jiangdu Water Control Project, Yangzhou City, Jiangsu Province. The starting point of the mid-line project is Danjiangkou Reservoir in the middle and upper reaches of the Han River, and the water supply areas are Henan, Hebei, Beijing and Tianjin. At present, the preliminary research work of the West Line Project has not yet entered the capital construction approval procedure.

The conception of the engineering scheme was put forward in 1952 when President Mao Zedong visited the Yellow River. Since then, through the analysis and comparison of more than 50 schemes, the water transfer scheme has achieved many valuable results. The planning area of South-to-North Water Transfer Project involves a population of 438 million, and the water transfer scale is 44.8 billion cubic meters.

The South-to-North Water Transfer Project mainly solves the problem of water shortage in northern China, especially in the Huang-Huai-Hai River Basin, with a population of 438 million. * * * There are three water transfer lines, namely the East Line, the Middle Line and the West Line, which are connected with the Yangtze River, the Yellow River, the Huaihe River and the Haihe River, forming an overall layout with "four horizontals and three verticals" as the main body, which is helpful to realize the rational allocation pattern of water resources in China.
