The composition about the South-to-North Water Transfer Project can be narrative or explanatory.

China is a country short of water, especially in some cities in the north. In order to solve this problem, the South-to-North Water Transfer Project was started at the end of 2002. Its completion will greatly alleviate the problem of water shortage in the north and improve the utilization rate of water resources. At present, the east, west and middle lines of the South-to-North Water Transfer Project have broken ground, which will solve the water problems in Beijing, Tianjin, Hebei, Henan, Anhui and Shandong. It is worth mentioning that during the construction of the South-to-North Water Transfer Project, special attention was paid to water quality and ecological problems.

Master Plan: After the idea of "South-to-North Water Transfer" was put forward in 1950s, after decades of research, the overall layout of South-to-North Water Transfer was determined as: transferring water from the upper, middle and lower reaches of the Yangtze River to meet the development needs of northwest and north China, namely, the west route project of South-to-North Water Transfer, the middle route project of South-to-North Water Transfer and the east route project of South-to-North Water Transfer.

Eco-environmental problems of South-to-North Water Transfer Project

Inter-basin water transfer may have favorable and unfavorable effects on the ecological environment of the water transfer area and the water receiving area. The eastern, central and western routes have basically the same beneficial effects on the water receiving area: the increase in water quantity provides a basic guarantee for the water demand of economic and social development, which is conducive to replenishing groundwater, curbing and gradually improving the deterioration of the ecological environment caused by water shortage, and protecting wetlands and biodiversity. It is considered that these adverse effects can be alleviated or avoided after taking necessary measures, and will not affect the project decision.
