China News Service, Beijing, May 3 (Reporter Chen Su) The reporter learned from the Chinese Ministry of Water Resources on the 3rd that as of May 3, the Tianjin-main line project of the South-to-North Water Diversion Middle Route had transferred 5 billion cubic meters of Yangtze River water to Tianjin, covering the water supply range Nearly 10 million people have benefited from 14 administrative districts such as the downtown area of Tianjin, the four districts around the city, and the Binhai New Area. South-to-north water transfer has become the main source of water in Tianjin.
Tianjin, with more than 16 million people, is a mega-city with a resource-based water shortage in China, which is a severely water-scarce region. Before the mid-line project of the South-to-North Water Diversion Project, urban production and living were mainly solved by diversion of water from the Luan River. The water for agriculture and the ecological environment depended on the weather. The utilization rate of surface water was close to 70%, far exceeding the carrying capacity of water resources. After the middle route of the South-to-North Water Diversion Project was opened to water, Tianjin had an adequate and stable water source for external diversion based on the Luanluan project. The central urban area, Binhai New Area and other economic development core areas have achieved dual water source guarantee, and the urban water supply is "dependent and unitary". , The vulnerability ”has been effectively resolved.
Since the middle route of South-to-North Water Diversion Project was officially opened to water, the Tianjin main line has achieved continuous and uninterrupted safe water supply for more than 1900 days, and the water quality has reached stable standards. At present, the project has entered the sixth water transfer year, and the water supply to Tianjin has been increasing year by year. The 2019-2020 water transfer year plans to supply 1.204 billion cubic meters of water to Tianjin.
Since the mid-line project was open to water, Tianjin has accelerated the process of groundwater source conversion and pressure extraction. In 2019, the city ’s groundwater extraction volume fell to 405 million cubic meters, and the deep groundwater extraction volume fell to 110 million cubic meters. The goal of "controlling the quantity to 211 million cubic meters" will lay the foundation for the realization of zero deep groundwater exploitation in 2020.
On April 1, this year, the first phase of the South-to-North Water Diversion Middle Line project replenishes the ecological environment of Tianjin. It plans to add 60 million cubic meters of water to improve the water environment of the urban rivers such as the Haihe River in downtown Tianjin.
On May 3, in Houmingzhuang Village, near Houming Water Plant, Dafengdui Town, Jinghai District, Tianjin, residents Aunt Wang could n’t help feeling, “I ca n’t think of drinking good water in my life before. People in Tianjin feel happy in life. "
Benefiting from the "Urban Tap Water Village to Village" project, about 60,000 residents in 55 villages in 6 towns and villages in Jinghai District of Tianjin drank water from South to North last year. Since 2018, Tianjin has launched a new round of rural drinking water quality improvement and efficiency projects. By extending the water pipe network and other measures, it has improved the drinking water quality of 1,157 villages and 1,299,000 rural residents in the city, and gradually realized the urbanization of rural water supply and urban and rural water supply. Integration.
Monitoring shows that in 2019, Tianjin's water eco-environmental quality achieved the best history, and the excellent proportion of water bodies in the national examination reached 50%, an increase of 10 percentage points year-on-year. For the first time, the proportion of inferior Class V water bodies dropped to 5%, a year-on-year decrease of 20 percentage points. Twelve rivers entering the sea have eliminated inferior Class V water bodies, and the quality of the city ’s water environment has improved significantly. Today on both sides of the Haihe River, the water is clear, the river is smooth, the shore is green, and the sky is blue. The water supply to the Haihe River through the South-to-North Water Diversion Project has greatly improved the living environment of the people in Jincheng. (Finish)
