The reporter learned from Shanxi Wanjiazhai Water Control Group on February 9 that in order to further assist the ecological recovery of the Yongding River Basin, the Wanjiazhai Yellow River diversion project will divert approximately 125 million cubic meters of Yellow River water to the Yongding River this year.

At Wanjiazhai Water Conservancy Hub, Panguan County, Shanxi Province, the Yellow River water was lifted by 356 meters through the third-level pumping station, and crossed mountains and ridges. Finally, it rushed out from the No. 1 tunnel of the North Trunk Line of the Wanjiazhai Yellow River, and poured into the Sanggan River through the Qili River, and then flowed into the Cetian Reservoir. After further purification, it was replenished to the Yongding River.
A relevant person in charge of Shanxi Wanjiazhai Water Holding Group Co., Ltd. said that Shanxi launched the Sanggan River ecological water replenishment project in 2017. The Yellow River water flowed into the Sanggan River through the Wanjiazhai Yellow River project and then flowed into the Yongding River. As of the end of 2024, the Wanjiazhai Yellow River diversion project has transported more than 1.3 billion cubic meters of water to the Yongding River, and has become the main force in ecological water replenishment to the Yongding River, providing important water resources guarantees for the capital's water supply safety and the realization of comprehensive management and ecological restoration of the entire Yongding River basin.

According to reports, in 2025, the Wanjiazhai Yellow River diversion project will further increase the water supply flow, and replenish 125 million cubic meters of water to the Yongding River ecology with a flow rate of 15-18 cubic meters per second, helping the water ecology of the basins along the route to continuously improve.
Yongding River is one of the important water systems in the Haihe River Basin and is an important water source conservation area, ecological barrier and ecological corridor in the Beijing-Tianjin-Hebei-Shan area. In 2024, with the joint efforts of relevant parties in the basin, the Yongding River once again achieved water throughout the year, and the overall ecological environment of the basin was effectively improved.
