Where does the South-to-North Water Transfer Project come from?

The starting point of the East Route of South-to-North Water Transfer Project is located in Jiangdu Water Control Project in Yangzhou City, Jiangsu Province, which provides production and domestic water to the eastern part of the Huang-Huai-Hai Plain, Jiaodong area and Beijing-Tianjin-Hebei area. The middle route project starts from Danjiangkou Reservoir in the middle and upper reaches of the Han River, and the water supply area ends in Henan, Hebei, Beijing and Tianjin. The west line project is still in the planning stage, and construction has not started.

The idea of South-to-North Water Diversion Project 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 total length of the east, middle and west trunk lines planned by the project is 4350 kilometers. The first phase of the East and Middle Lines is 2,899 kilometers long, and the first-class supporting branch canals in six provinces and cities along the line are about 2,700 kilometers.

The South-to-North Water Transfer Project has optimized the allocation of water resources. The cumulative water transfer of the project is nearly 30 billion cubic meters, and the population directly benefits more than1.200 million, which has become the main source of domestic water in many important cities. The South-to-North Water Diversion Project provides reliable water resources support for the coordinated development of Beijing-Tianjin-Hebei and the construction of xiong'an new area.

"South Water" accounts for more than 70% of the tap water supply in the central city of Beijing. All the administrative districts in Tianjin 14 use "South Water", and many urban districts in Henan 100% use "South Water", benefiting more than 90 counties and districts in Shijiazhuang, Handan, Cangzhou and other cities in Hebei. Jiangsu has formed a pattern of double-line water supply, and the water supply guarantee rate in the receiving area has increased by 20%-30%.
