CCTV News: According to the Ministry of Water Resources, in order to continue to promote the recovery of rivers and lake ecological environment in North China and the comprehensive management of groundwater over-exploitation, the Ministry of Water Resources recently issued and implemented the "Water Replenishment Plan for the 2025 Full Line of the Beijing-Hangzhou Grand Canal". On February 10, the Liuwuhe control gate of the Shandong section of the first phase of the South-to-North Water Diversion East Line Project was opened, and the emergency north extension project of the East Line of the South-to-North Water Diversion East Line was replenished to the small canal; on February 20, the water sources of Miyun Reservoir and Huairou Reservoir were diverted through Beijing and Mimi The canal is water replenished through the Wenyu River to the northern canal. The full line of the Beijing-Hangzhou Grand Canal will be fully launched in 2025.

The 2025 water replenishment plan will last until the end of June, with the northern section of the Yellow River of the Beijing-Hangzhou Grand Canal as the main connecting route, starting from Dongbianmen, Beijing in the north, passing through Tonghui River and Beihua River to Sancha River mouth in Tianjin.

It involves four provinces and cities, including Beijing, Tianjin, Hebei and Shandong, and flows through 8 prefecture-level administrative regions and 31 County-level administrative district. By optimizing the allocation and dispatching of water supply for the emergency water supply project of the first phase of the South-to-North Water Diversion East Line, local water, yellow water diversion, Luan water diversion, recycled water and rainfall water, it is estimated that 556 million cubic meters of water replenishment will be provided. Among them, the water volume entering the Grand Canal of Beijing and Hangzhou is 529 million cubic meters, the total length of the water replenishment line is 1,274 kilometers, and the area of ​​irrigation of deep groundwater is replaced by 460,000 mu. On the basis of maintaining water in the entire section of the river south of the Yellow River of the Beijing-Hangzhou Grand Canal, the entire line of the Beijing-Hangzhou Grand Canal will be opened to water and try to maintain water in the entire line. The groundwater level around the water replenishing river will rise or remain stable, and the water ecosystem will be restored and improved.

During the water replenishment period, the Ministry of Water Resources will organize relevant units and local governments along the route to strengthen river cleaning and rectification, ensure joint water scheduling, implement water source replacement and groundwater replenishment, strengthen water pollution prevention and control, strengthen dynamic tracking and monitoring, and add The water protection efforts of large pipes ensure orderly implementation of water replenishment.
