Application of composite geomembrane in South to North Water Diversion Project

"South to North Water Diversion Project" is a strategic project of the people's Republic of China. It refers to transferring water resources from the upper, middle and lower reaches of the Yangtze River basin to the water shortage areas in North China, Huaihai plain and Northwest China according to the regional characteristics of China's territory.

In September 2012, the relocation of Danjiangkou Reservoir Area in the Middle Route Project of South to north water transfer was completed. The south to north water diversion 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. Three water diversion lines, namely the east line, the middle line and the west line, are recommended. Through the connection of the three water transfer lines with the Yangtze River, the Yellow River, the Huaihe River and the Haihe River, the overall layout with "four horizontal and three vertical" as the main body is formed, which is conducive to the realization of the reasonable allocation pattern of water resources allocation from north to South and mutual benefit between the East and the West. Up to now, the west line project has not started construction.
