Southwest Regional Series Water Conveyor and Diversion Project

Central Yunnan Water Diversion Project

The second phase of the comprehensive utilization of water resources of Ludila Hydropower Station in Dali Prefecture is to meet the water demand of urban life, industry and efficient agricultural development in Binchuan County before the completion of the water diversion project. After the completion of the water diversion project in central Yunnan, the water demand of urban life and industry in Dali Prefecture will be further guaranteed. The water supply can be 12.15 million m and the industrial water supply 5.67 million m to Binchuan County, 68.33 million m³ of water supply to 460000 mu of arable land in the irrigation area; It can provide 118.61 million m³ of urban and industrial water supply to the 1 million population of Xiangyun County, including 64.56 million m³ of urban water supply and 54.05 million m³ of industrial water supply. At the same time, it creates conditions for the central Yunnan water diversion project to supply water to the central Yunnan urban agglomeration with Kunming as the core.
