In order to continuously promote the eco-environment rehabilitation of rivers and lakes in North China and the comprehensive management of groundwater over-exploitation, Ministry of Water Resources recently issued the 2025 Water Recharge Plan for the Full-channel Connectivity of the Beijing-Hangzhou Grand Canal.
With the section of the Beijing-Hangzhou Grand Canal in the north of the Yellow River as the main connectivity route, the implementation of 2025 water recharge plan will continue until the end of June, involving 4 provinces and municipalities of Beijing, Tianjin, Hebei and Shandong, and flowing through 8 prefecture-level administrative regions and 31 county-level administrative regions. By means of optimizing the distribution and scheduling of the water from North Extension Emergency Water Supply Project for the first phase of the South-to-North Water Diversion Project (the Eastern Route), the local water sources in Beijing, Tianjin, Hebei and Shandong provinces, the diverted Yellow River water, and the recycled water and stormwater, it is expected to render a recharge volume of 556 million m3, of which 529 million m3 enters the Beijing-Hangzhou Grand Canal. The total length of the replenishment line is 1274 km, finally achieving the full-channel connectivity of the Beijing-Hangzhou Grand Canal, the rise of the groundwater level around the recharge channel and the restoration of the aquatic ecosystem.
During the water recharge period, Ministry of Water Resources will organize relevant units and local governments along the canal to strengthen river channel cleaning and regulation, ensure joint flow scheduling, implement water source replacement and groundwater recharge, reinforce water pollution prevention and control, and enhance dynamic tracking and monitoring, so as to guarantee orderly implementation of water recharge.
