In the past seven years, the first phase of the East and Central Lines of the South-to-North Water Diversion Project has been fully connected to the water, with a total of 49.4 billion cubic meters of water transfer, which has played a huge economic, social and ecological benefit, and the sense of gain, happiness and security of the people along the route has continued to increase, making great contributions to building a well-off society in an all-round way, implementing the national "River Strategy", supporting the implementation of major national strategies, and building a beautiful China.
Change the pattern of water supply in the vast northern region
The pattern of water resource allocation continues to be optimized
The first phase of the east and central lines of the South-to-North Water Diversion Project has been fully completed and connected, communicating the four major river basins of The Long, Yellow, Huai and Hai, and initially constructing a water grid bureau of North-South allocation and east-west mutual benefit in China. In the past seven years, the project operation managers have followed the laws of project operation management and achieved a breakthrough in the continuous increase of annual water diversion from more than 2 billion cubic meters to nearly 10 billion cubic meters through the implementation of scientific scheduling. On the basis of accurate and precise scheduling, make full use of the favorable opportunity of pre-flood tengku capacity, make full use of the project's water transmission capacity, transfer water to the north, increase water supply, and exceed the average water supply scale of the planned multi-year for two consecutive years in the first phase of the 2020 and 2021 central line projects. Especially in 2021, in the face of multiple challenges such as the impact of exceptionally heavy rainstorms and the rebound of the new crown epidemic, the project management unit has achieved the annual water transfer of the central line project by strengthening forecasting, early warning, rehearsal and pre-planning measures, scientific and accurate scheduling of the project, and completed 121% of the annual plan. The south-to-north water diversion has become a new lifeline for the water supply of many northern cities: more than 70% of the water supply in Beijing is diverted from the south to the north; almost all of the water supply in the main urban area of Tianjin is south water. With the official opening of the emergency water supply project of the northern extension of the eastern line of the South-to-North Water Diversion Project, the water safety guarantee capabilities of Tianjin, Hebei and other places have been further enhanced... The shortage of water resources in the northern region of our country has been fundamentally alleviated.

Happiness and security are significantly enhanced
The South-to-North Water Diversion Project has become an unceasing green lifeline, guarding the drinking water safety of hundreds of millions of people along the project. In the past seven years, nearly 50 billion cubic meters of high-quality water have continuously flowed into thousands of households in the north. According to statistics, as of December 12, 2021, the first phase of the East and Central Lines has accumulated 49.4 billion cubic meters of water transfer, of which the cumulative water transfer of the first phase of the Central Line project has exceeded 44.1 billion cubic meters, and the cumulative water transfer of the first phase of the East Line project into Shandong is 5.288 billion cubic meters. Through the promotion of iron fist pollution control and continuous strengthening of supervision and management, the water quality of the South-to-North Water Diversion Project has been sustained and stable for a long time, and the water quality of the water transmission trunk line of the first phase of the Eastern Line project has reached the standard and has been continuously and stably maintained above the surface water quality class III.; the water quality of the Danjiangkou Reservoir and the central line trunk line has been stable above the surface water quality class II. Due to the excellent water quality and high water supply guarantee rate, the dependence of the water-receiving areas on the south-to-north water diversion is getting higher and higher. In Beijing, the hardness of tap water has risen from the past 380 mg /l to 120 mg/l; in Henan, more than ten provinces and municipalities use Shangnan water, of which more than 90% of the residents in the central urban area of Zhengzhou use water for the south-to-north diversion of water, basically bidding farewell to the history of drinking Yellow River water; more than 5 million people in the Heilonggang River Basin of Hebei Province have completely bid farewell to the history of drinking high-fluoride water and brackish water for generations; the eastern line project has formed a "T" shaped "artery" on the land of Qilu, which not only provides residents along the line with living water and production of necessary water. It has also become a "life-saving water" to cope with extreme weather such as drought, and in 2017 and 2018, the eastern route once became the main force to ensure the safety of water supply in Qingdao, Yantai and other cities.

Promote the recovery of the ecological environment of rivers and lakes
Vigorously promote the construction of ecological civilization along the route
Green is always the background color of the South-to-North Water Diversion Project. The "Master Plan for the South-to-North Water Diversion Project" proposes that the fundamental goal of the South-to-North Water Diversion Project is to improve and restore the ecological environment of the Huang-Huai-Hai Plain and the Jiaodong area. In the past seven years, through comprehensive measures such as water source replacement and ecological water replenishment, the ecological safety of rivers and lakes along the route has been effectively guaranteed. The lakes in the water-receiving areas along the eastern line use the pumped river water to replenish the amount of evaporative seepage in a timely manner, the lake water storage remains stable, the ecological environment continues to improve, and the "Spring City" in Jinan reproduces the scene of spring water gushing in all seasons; the central line has accumulated more than 7 billion cubic meters of ecological water replenishment to more than 50 rivers in the north, which has promoted the revival of a large number of rivers and lakes such as the Tuotuo River, the Waterfall River, the South Juma River, the Daqing River, and the Baiyangdian River, and the ecological environment of the rivers and lakes has been significantly improved In 2020, the shallow groundwater level in North China rebounded by 0.23 meters from the previous year, and for the first time after years of decline, the groundwater level in the Plain area of Beijing rose for 6 consecutive years, and at the end of 2020 compared with the end of 2014, the shallow groundwater level in Beijing rose by 2.37 meters; and the water storage capacity of Miyun Reservoir broke the record high of 3.358 billion cubic meters on August 23, 2021. From August to September 2021, for the first time, the ecological water replenishment of the Yongding River was made through the discharge gate of the Daning Pressure Regulating Pond in the Beijing section, helping the Yongding River to achieve the first time since 1996 that the 865-kilometer river was fully connected to the water. The once dry depressions, lakes, rivers, canals and wetlands along the project line have come back to life, and a beautiful landscape of smooth rivers, clear water, green shores and beautiful scenery has been initially formed.
