[7] Luanhe River Diversion Project(1982-1983) | Planning Stage | Preliminary Research

In August 1981, the State Council decided to build People’s Republic of China Luanhe River Diversion Project, listed as the national key construction project. Site survey, design and construction work of the project was assigned to Tianjin local government. The project is a huge project across the Haihe River, Luanhe River, including the construction of Panjiakou Reservoir and Daheiting Reservoir in Qianxi County. The Luanhe River Diversion to Tianjin (Northern Line) and diversion to Tangshan (Southern line) are two large water diversion Projects, connecting Luanhe River river, Douhe River, Zhouhe River, Huanxianghe River and Taohe River. It has become, in connection with large reservoirs at Yuqiao, Qiuzhuang, forming a water gigantic water storage, including functions of swilling water, distributing water, delivering water, and purifying water.

Diversion canal 234 kilometers in length, but also in the middle of the Luanhe River watershed and Ji canal a more than 12 kilometers of mountain tunnel, to river more than 100 km, 64 km canal special excavation, all engineering excavated rocks up to 1 million 400 thousand cubic meters. In order to benefit the people of Tianjin, ordered the Tianjin municipal government in 1983 to Luan River to Tianjin.

Image of Daheiting ReservoirCompared to Daheiting Reservoir, Panjiakou Reservoir is Luanhe project’s “leading tap”, a comprehensive set of water conservancy industry and city water supply, flood control, ecological and environmental protection, agricultural irrigation, power generation. The ground of the reservoir is rocks in complex geological structure, submitted to water erosion and water flowing. It creates a series of peaks and rocks and steep cliffs and crags, plus blue lake, formed a comparable with the Guilin Scenery landscape, which adds to the difficulty of Luanhe Water Diversion Project.
