How many years did the Yangtze River water enter Weifang through the South-to-North Water Transfer Project?

The Yangtze River water entered Weifang City through the South-to-North Water Transfer Project on 20 13.

"South-to-North Water Diversion Project" (pinyin: nán ShuǐbīI diào), namely "South-to-North Water Diversion Project", is a strategic project of China people, 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 in Yangzhou, 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 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.

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. * * * 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.
