Where is the water source for the South-to-North Water Transfer Project?

1. Water source of East Route Project of South-to-North Water Transfer Project: Jiangdu Water Control Project in Jiangsu Province.

The East Line Project plans to take water from the main stream of the Yangtze River near Yangzhou, Jiangsu Province, and use the Beijing-Hangzhou Grand Canal and its parallel rivers to deliver water, connecting Hongze Lake, Roman Lake, Nansi Lake and Dongping Lake, and serve as a water storage reservoir. After pumping water into Dongping Lake step by step, it will be divided into two ways.

After crossing the Yellow River, The Journey to the West flowed to Tianjin by himself. The main water conveyance line from the Yangtze River to Tianjin Beidagang Reservoir is about 1 156 km long? ; The other road connects the Yellow River-Jinan-Qingdao channel eastward through the newly-built water conveyance trunk line in Jiaodong area, and supplies water to Jiaodong area.

2. Water source of the Middle Route of South-to-North Water Transfer Project: Danjiangkou Reservoir, Hubei Province.

The Middle Route Project of South-to-North Water Transfer is to divert water from Danjiangkou Reservoir in the middle and upper reaches of Hanjiang River, the largest tributary of the Yangtze River, and excavate the main canal at the head of the project in Jiuzhong Town, Xichuan County, Henan Province on the east bank of Danjiangkou Reservoir.

Through the watershed of the Yangtze River basin and Huaihe River basin, the city will be protected, and canals will be dug along the central and western edges of the North China Plain, crossing the Xingyang Yellow River along the west side of the Beijing-Guangzhou Railway and flowing into Tuancheng Lake in the Summer Palace in Beijing.

3. Water sources of the West Route of South-to-North Water Transfer Project: Tianhe (upper reaches of the Yangtze River), Yalong River (tributaries of the Yangtze River) and Dadu River in Sichuan.

The West Route Project of South-to-North Water Diversion is located in the western and northern regions of Sichuan, Qinghai, Gansu, Ningxia, Mongolia, Shaanxi and Shanxi in the southeast of Qinghai-Tibet Plateau in China. The elevation of the dam site is 2900-4000m. The diversion trunk line adopts diversion tunnel to cross the Yangtze River and Yellow River watershed to transfer water to the Yellow River, and the long-distance tunnel adopts gravity flow scheme.

The concept 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.

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.

By the end of 20 18, 12 and 12, the East Middle Route Project of South-to-North Water Transfer has transferred 22.2 billion cubic meters of water, and the water supply has increased continuously and rapidly, which has optimized the allocation pattern of water resources in China, effectively supported the economic and social development of water receiving areas and water source areas, and promoted the construction of ecological civilization.

As of June 2 1 and June 20 19, the emergency trial drainage of the north extension of the first phase of the East Route of South-to-North Water Transfer Project was successfully completed.
