A total of 36.122 billion cubic meters of water was delivered, and the comprehensive benefits of the project far exceeded expectations——
The Middle Route of the South-to-North Water Diversion Project continues to moisturize Beijing, Tianjin and Hebei
Recently, the reporter learned from the Construction and Management Bureau of the Middle Route of the South-to-North Water Diversion Project that the total water delivery of the Middle Route of the South-to-North Water Diversion Project was 36.122 billion cubic meters, of which 10 billion cubic meters were supplied to Hebei Province, 6.006 billion cubic meters were supplied to Tianjin, and 6.213 billion cubic meters were supplied to Beijing. Henan's water supply is 12.328 billion cubic meters, and the comprehensive benefits of the project far exceed expectations.
Since the coordinated development of Beijing-Tianjin-Hebei became a national strategy in 2014, the water from the south that has been continuously transported by the mid-line project has drawn a new picture of beautiful scenery for the coordinated development of Beijing-Tianjin-Hebei.
In Hebei, the water receiving area used to have difficulty in drafting and water.
The main canal of the middle route of the South-to-North Water Transfer Project and supporting projects have built a safe water supply network system.
Through more than 40 water dividers and 128 surface water plants, high-quality South Water will be delivered to Shijiazhuang, Langfang, Baoding, Cangzhou, Hengshui, Xingtai, Handan, Dingzhou, Xinji and Xiongan New Districts.
Tian Yong, deputy director of the Construction and Management Bureau of the Middle Route of the South-to-North Water Diversion, Secretary of the Party Committee and Director of the Hebei Branch, said that since the middle route of the South-to-North Water Diversion Project was opened, the water quality of the water supply has reached Class II and above standards, which has significantly improved the water quality of the water-receiving areas.
Taking the urban area of Shijiazhuang as an example, the hardness of tap water has dropped from 330-350 mg/l to 150-170 mg/l. The quality of drinking water for residents has been greatly improved. More than 5 million people in the Heilonggang River Basin in Hebei Province have completely bid farewell to their ancestors and their ancestors. The history of water and high-fluorine water.
In Tianjin, the city's total water supply from the South-to-North Water Diversion Project increased from 2.41 billion cubic meters in 2014 to 2.782 billion cubic meters in 2020. The contradiction of "dependency, unity, and vulnerability" of urban water supply has been effectively resolved.
Hu Jinzhou, Secretary of the Party Committee and Director of the Tianjin Branch of the Construction and Management Bureau of the South-to-North Water Diversion Middle Route, said that Tianjin’s construction of a centralized water supply plant, extension of the tap water pipe network, and gradually replacing groundwater sources with south-to-north water diversion has improved the drinking water quality of 2,868 million rural residents in 2,817 villages. The integration of urban and rural water supply provides an important basic guarantee for the construction of a high-quality well-off society.
Hu Jinzhou said that last year, Tianjin scientifically dispatched the supporting project of the South-to-North Water Diversion in the city, made full use of various water sources, implemented ecological replenishment of rivers and lakes to the maximum. The annual ecological replenishment was 1.426 billion cubic meters, and the central urban area and the four districts around the city were connected to the Haihe River. The water cycle system and other key projects have upgraded the protection of wetland protection areas. The proportion of good water quality in the city's state-controlled sections has increased from 35% in 2017 to 55%, and the proportion of sections with inferior grade V water quality has dropped from 40% to zero. The water ecological environment quality has reached a historical level. The highest level.
In Beijing, 6.213 billion cubic meters of South Water has increased Beijing’s total water resources and improved water conditions for urban residents, directly benefiting more than 13 million people.
The arrival of Nanshui not only significantly changed the capital's water resources guarantee pattern and water supply pattern, but also won a precious water conservation period for Beijing and improved the urban ecological environment.
The Daning Reservoir, Tuancheng Lake Regulating Pool, and Yizhuang Regulating Pool of the South-to-North Water Diversion Project realized water storage, increasing the water surface area by 550 hectares; expanding the water area by storing water in the Ming Tombs, Huairou, Miyun and other water areas, the Miyun Reservoir increased the water surface by more than 5,000 Hectares; replenishing water to urban rivers and lakes and replenishing groundwater. The groundwater level has risen by 3.26 meters from 25.75 meters at the end of 2015, and it has risen for 5 consecutive years.
The Middle Route of the South-to-North Water Diversion Project runs through the Beijing-Tianjin-Hebei region, forming a new pattern of interconnection, interoperability and mutual assistance among the three water systems of the Beijing-Tianjin-Hebei region. It will realize the unified dispatch of water resources, relieve Beijing’s non-capital functions, promote the coordinated development of Beijing-Tianjin-Hebei, and promote Hebei The construction of Xiong’an New District and Beijing’s urban sub-center provides a strong guarantee of water resources for effective treatment of “big city diseases”.
