How many kilometers is the total length of the South-to-North Water Transfer Project?

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 South-to-North Water Transfer Project is a strategic project in People's Republic of China (PRC), which is divided into three routes: east, middle and west. The starting point of the East Line Project is located in Jiangdu Water Control Project, Yangzhou City, Jiangsu Province. The starting point of the middle route project is located in Danjiangkou Reservoir in the middle and upper reaches of Hanjiang River, and the water receiving areas are Henan, Hebei, Beijing and Tianjin.

The conception of the engineering scheme began with 1952. Through the analysis and comparison of more than 50 schemes, the water transfer scheme has achieved many valuable results. From 2065438 to September 2002, the relocation of migrants in Danjiangkou reservoir area of the Middle Route of South-to-North Water Transfer Project was fully completed. 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.

Configuration mode

* * * There are three water diversion routes: east, middle and west. Three water transfer lines are connected with the Yangtze River, Yellow River, Huaihe River and Haihe River, forming an overall layout with "four horizontals and three verticals" as the main body. In order to realize the rational allocation pattern of water resources in China, that is, north-south allocation and east-west mutual assistance. The Middle Route Project of South-to-North Water Transfer and the East Route Project of South-to-North Water Transfer (Phase I) have been completed, and water has been transferred to the northern region. The west line project is still in the planning stage, and construction has not started.

Make use of the existing water diversion projects in Jiangsu Province, gradually expand the scale of water diversion and extend the water transmission lines. The East Route Project draws water from the Yangtze River from Yangzhou in the lower reaches of the Yangtze River, and gradually pumps water to the north by using the Beijing-Hangzhou Grand Canal and its parallel rivers. It also connects Hongze Lake, Roman Lake, Nansi Lake and Dongping Lake, and plays a role in storage. After leaving Dongping Lake, the water will be transported to the The Journey to the West in two ways and cross the Yellow River through a tunnel near Yishan. The other road goes eastward, leading to Yantai and Weihai through the economic trunk line of South-to-North Water Transfer in Jiaodong area.
