The 2022-2023 water diversion task of the northern extension emergency water supply project of the East Line of the South-to-North Water Diversion Project was successfully completed

It is understood that this year is the fourth water diversion carried out since the trial operation of the Beiyan Emergency Water Supply Project in 2019. The start time is early, the water diversion time is long, the water diversion volume is large, and the dispatch Operation management is difficult, and major breakthroughs have been made in four aspects compared with previous years. First, compared with previous years, the water diversion period is concentrated from March to May. As early as December 9, 2022, the Beiyan Emergency Water Supply Project started this year's water diversion work, setting a precedent for the project's ice age water transfer, aiming to Ensure spring irrigation reserve water sources in the Tianjin-Hebei region, ensure food security, and further consolidate the effectiveness of the recovery of the ecological environment of rivers and lakes in North China and the comprehensive management of groundwater overexploitation. Second, it operated without interruption for 174 days, setting a record for the longest water diversion time in the Beiyan Emergency Water Supply Project. Third, 238 million cubic meters of water will be transferred to Hebei and Tianjin this year, completing 110% of the annual plan, which is the largest amount of water transferred in the previous North Extension Emergency Water Supply Project. Fourth, it once again helped to connect the entire Beijing-Hangzhou Grand Canal, replenishing 145 million cubic meters of water, becoming the largest source of water for the entire Beijing-Hangzhou Grand Canal in 2023. After experiencing the test of water delivery during the first glacial period, we jointly implemented multi-water source and multi-project joint dispatching with Lubei, Panzhuang Yellow River Diversion and Yuecheng Reservoirs in the first phase of the East Route of the South-to-North Water Diversion Project, and successfully responded to the dispatching and operation management since the North Extension emergency water supply project was trialled. The most complex challenge.

This year is the tenth water diversion year since the first phase of the east route of the South-to-North Water Diversion Project was officially opened in 2013. The cumulative water pumped from the river reached 41.6 billion cubic meters, and 25 large and medium-sized enterprises along the route The city and 83.59 million people have benefited, providing strong water resources support and guarantee for the economic and social development of the water-receiving areas. The comprehensive economic, social, ecological and other benefits are significant. It has become an important factor in optimizing water resources allocation, ensuring the safety of drinking water for the people, reviving the ecological environment of rivers and lakes, and Smooth the lifeline of economic circulation between the north and the south.
