Work began on Saturday to construct a reservoir in central China’s Chongqing metropolitan region, website CGTN reports.
The Zaodu Reservoir project, which is expected to cost $14bn, will benefit more than 3.4 million residents when it is completed in 2027.
The work will involve building a 105m-high dam and a network of water pipelines.
According to CGTN, the reservoir will increase the region’s annual water supply by about 179 million cubic metres and a 94km-long network of pipes will irrigate an area of around 11,300ha.
