The construction of the Changtang Reservoir project in Guangxi is a milestone event, marking a new stage in the management and utilization of water resources in the region.

The Changtang Reservoir Project in Guangxi is one of the 150 major water conservancy projects deployed and implemented by the State Council. It has been included in the National 14th Five Year Plan and the 2035 Long Range Goal Outline, as well as the National 14th Five Year Water Safety Guarantee Plan. The construction of this project aims to improve the utilization efficiency of local water resources, meet the diversified needs of urban and rural water supply, irrigation, flood control, ecological replenishment, and take into account the comprehensive utilization of power generation, which is of great significance for promoting regional economic and social development.

This project is located in Guilin City, Guangxi Zhuang Autonomous Region, specifically on the main stream of Xihe River, a primary tributary of the Luoqing River in the upper reaches of the Liujiang River. The region has superior solar and thermal conditions, beautiful natural scenery, and abundant water resources, arable land resources, and tourism resources. The Changtang Reservoir Project consists of a water source reservoir and a water conveyance project. The water source reservoir adopts a roller compacted concrete gravity dam design, with a maximum dam height of 77.5 meters and a normal storage level of 196 meters. The total storage capacity reaches 235 million cubic meters. The total length of the water transmission project is 244.58 kilometers, consisting of the Lingui and Yongfu trunk lines, as well as their sub trunk and branch lines. The total investment of the project is about 7.98 billion yuan, and the total construction period is expected to be 52 months.

The Changtang Reservoir project will provide urban and rural domestic water and industrial production water for Guilin New Area, Yongfu County, and Guilin Economic and Technological Development Zone, while expanding the irrigation area of economic crops, with an estimated additional irrigation area of 298000 acres. After the completion of the project, it will enhance the flood control capacity of Yongfu County and protect the ecological environment of the Li River through ecological water replenishment. The installed capacity of the dam rear power station has reached 28000 kilowatts, and it is expected that the average annual power generation will reach 88.21 million kilowatt hours, achieving comprehensive utilization of water resources.

The construction of the Changtang Reservoir project will greatly enhance the water resource allocation capacity of Guilin and surrounding areas, providing strong support for the sustainable development of regional economy and society. Meanwhile, by expanding the irrigation area and providing stable water sources, it will effectively promote the development of local agriculture and industry. The project will effectively protect the ecological environment of the Li River and improve the quality of the local ecological environment through its ecological water replenishment function. At the same time, environmental protection will also be emphasized in the construction process, achieving harmonious coexistence between ecological balance and economic development.
