has suffered from long drought spells, such as a period of 30 months without heavy rains in
Kunming. Water scarcity has been described as the "biggest bottleneck restricting the sustainable development of Central Yunnan." The idea of diverting water from the Jinsha River to Central Yunnan was first proposed by Yunnan's vice-governor
162:
This water will be used for domestic and industrial water supply (2.231 m (589 U.S. gal) million), agricultural water supply (500 m (130,000 U.S. gal) million), as well as for improving the ecology of lakes in the region (672 m (178,000 U.S. gal) million).

The project will include the world's longest water tunnel, the world's largest underground pump room, and largest pump capacity in Asia. In addition, it deals with challenging geological conditions due to passing through a number of faults. It crosses the four major watersheds of Yunnan: that of the

Central Yunnan is a dry region in China, where currently, only 700 m (180,000 U.S. gal) of water is available per capita annually, compared to a 1,700 m (450,000 U.S. gal) recommended minimum. At the same time, Central Yunnan accounts for 68% of Yunnan's GDP. The region

Once completed, the project would improve water availability for 11 million people, spread over 35 counties in Yunnan and a total area of 36,900 km (14,200 sq mi). Over 3.403 m (899 U.S. gal) billion of water would be transported through the channels annually by 2040.

Construction commenced on 4 August 2017, with a planned construction time of 8 years. The project includes 58 tunnels with a total length of 612 km (380 mi), 25 inverted siphons, 17 aqueducts, and 15 culverts.

Since the inlet at the Jinsha River does not include a dam structure, the impact on the source river is expected to be small.
