On August 25, the Yellow River Crossing Project of the middle line of the south to North Water Transfer project passed the completion acceptance of the design unit project presided over by the Ministry of water resources. So far, all 155 design unit projects of the East and middle lines of the south to North Water Transfer Project have passed the completion acceptance of the Ministry of water resources. According to statistics, the South-to-North Water Transfer Project has transferred more than 56 billion cubic meters of water and benefited more than 150 million people, fully demonstrating the benefits of this project. Major nodes of the South-to-North Water Transfer Project: all 155 design unit projects have passed the completion acceptance. The Yellow River Crossing Project (Yellow River Crossing Project) of the middle line of the South-to-North Water Transfer Project has passed the acceptance, which means that all 155 design unit projects of the East and middle lines of the South-to-North Water transfer project have passed the completion acceptance, and also marks that the project has entered the formal operation stage. The East Route of the South-to-North Water Transfer project starts from the Jiangdu water conservancy project in Yangzhou City, and the Yangtze River flows northward into Shandong; The middle line diverts water from the Taocha canal head gate of Danjiangkou reservoir into the canal, and the south water flows thousands of miles, moistening Henan, Hebei, Tianjin and Beijing. Among the 155 design unit projects that have passed the completion acceptance of the Ministry of water resources, 68 are in the east line and 87 are in the middle line of the South-to-North Water Transfer Project. The Yellow River crossing project that has passed the acceptance is the control project of the middle line of the South-to-North Water Transfer Project, and also the first project that uses large-diameter shield construction to cross large rivers in China. After the Yellow River crossing project started in 2005, a series of technical problems were solved. Since the completion of the project and water supply, the operation has been safe and stable. According to the relevant responsible person of the Ministry of water resources, all 155 design unit projects have passed the completion acceptance, which is a major node since the completion of the first phase of the East and middle line of the south to North Water Transfer Project, laying a foundation for the completion acceptance of the first phase of the East and middle line of the south to North Water Transfer Project and the high-quality development of subsequent projects. Next, the Ministry of water resources will accelerate the preparations for the completion acceptance of the East and middle line phase I of the South-to-North Water Transfer Project, and constantly improve the comprehensive benefits of the project. Water diversion exceeded 56 billion cubic meters: it changed the water supply pattern in some areas in the north. The first phase of the East and middle line of the South-to-North Water Diversion Project was completed in November 2013 and December 2014 respectively. According to the statistics of China South to North Water Transfer Group Co., Ltd., as of 8:00 on August 25, a total of 56.324 billion cubic meters of water had been transferred from the East and middle lines of the south to North Water Transfer Project. After deducting losses, the East and middle lines of the south to North Water Transfer Project have supplied 54.424 billion cubic meters of water to Henan, Hebei, Tianjin, Beijing and Shandong. Experts believe that since the South-to-North Water Diversion Project was fully opened, it has changed the water supply pattern in some areas in the north, and at the same time promoted the recovery of the river and lake ecological environment in the water receiving area and the recovery of the groundwater level, which has produced tremendous economic, social and ecological benefits. As for the middle line of South-to-North Water Transfer, the water supply quality of Danjiangkou reservoir and the middle line is class II or above of surface water quality. The drinking water of the Yellow River has been replaced by the south water in many places in Henan Province. More than 5 million people in Cangzhou, Hengshui and Handan of Hebei Province bid farewell to the long-term drinking of high fluorine water and brackish water because of the south water. More than 150 million people benefited: the level of water supply security has been improved. The reporter learned from the south to North Water Transfer group company that by the end of December 2021, 42 cities had benefited from the East and middle line phase I of the south to North Water Transfer Project. Among them, 24 cities benefited from the middle line and 18 cities benefited from the east line. As far as the middle line of the south to north water transfer is concerned, the south water has become the water supply for some large and medium-sized cities along the line
