China has established a water control infrastructure system that is currently the largest in scale, widest in scope, and has the largest population of beneficiaries in the world. The Ministry of Water Affairs has announced that it will implement the National Water Network Key Project by the end of this year to enhance China’s capacity for unified coordination of water resources, water supply guarantee, and strategic stockpiling

The South-to-North Water Diversion Project is the largest of its kind ever undertaken. The project involves drawing water from southern rivers and supplying it to the dry north.

This massive scheme has already taken 50 years from conception to commencement and is expected to take almost as long to construct. Planned for completion in 2050, it will eventually divert 44.8 billion cubic metres of water annually to the population centres of the drier north. 

When finished, the work will link China’s four main rivers – the Yangtze, Yellow River, Huaihe and Haihe – and requires the construction of three diversion routes, stretching south-to-north across the eastern, central and western parts of the country. 

The complete project is expected to cost $62bn – more than twice as much as the country’s controversial Three Gorges Dam.
