In 8 years, the amount of water saved in cities across the country is equivalent to the annual water transfer of 5 mid-route South-to-North Water Diversion Projects——
Save intensive water and get results
When the water comes, the river will live!
From the stinking ditch that stayed away to the beautiful scenery with clear water, now the Liangma River in Chaoyang District, Beijing has a new look.
"At present, the clear living water is mainly supplied from a nearby reclaimed water plant. The sewage has been treated and turned waste into treasure. The green irrigation on both sides of the strait also uses reclaimed water, saving approximately 380,000 cubic meters of fresh water annually." Tan introduced.
From May 9th to May 15th this year is the 30th National Urban Water Conservation Publicity Week.
In recent years, my country has put water conservation at the priority of urban water wading, and has built an urban water system that is interrelated with water supply, water environment management, and water safety.
According to data released by the Ministry of Housing and Urban-Rural Development, from 2012 to 2020, the cumulative amount of water saved in cities across the country has reached 45.3 billion cubic meters, which is equivalent to the annual water transfer volume of five South-to-North Water Transfer Projects.
The total water consumption in cities across the country only accounts for about 10% of the total water consumption in the country, but it supports 60% of the country’s population and more than 70% of GDP.
Promote recycled water to become the city's "second water source". In 2020, the amount of recycled water used in cities across the country will reach 14.6 billion cubic meters, a four-fold increase from 2012, accounting for 23.2% of the city's total water supply.
—— Carry out throttling in key areas, improve efficiency and save water.
In the factory area of Hubei Yichang Xindaxing Concrete Co., Ltd., there is a huge sedimentation reservoir.
"The collected rainwater and ground flushing water will become recyclable clean water after seven-stage precipitation, which will be piped back to the mixing plant for production." According to the person in charge of the company, about 80% of the company's water consumption comes from recycled water. Annual cost savings of more than 400,000 yuan.
The annual water supply in Shaoxing, Zhejiang is nearly 100 million cubic meters, and the total pipe network length is more than 2,000 kilometers.
By using big data and other technologies to improve the accuracy of finding leaks and the efficiency of emergency repairs, the leakage rate of the water supply pipe network was reduced to 4%.
According to the relevant person in charge of the Urban Construction Department of the Ministry of Housing and Urban-Rural Development, in recent years, various localities have accelerated the transformation of old water supply pipe networks and improved the operation and management level of the pipe network. The leakage rate of the national urban water supply pipe network has steadily decreased.
——Promote the construction of sponge cities and innovate concepts to save water.
Permeable bricks replace traditional hard pavements, and rainwater collected by sponge facilities such as grass-planting ditches and sunken green spaces can be used as sprinkling water for greening.
With the development of the Sponge City, the quality of life of the residents of Yujingyuan Community in Pingxiang, Jiangxi Province has been further improved.
In recent years, the concept of sponge city construction has gradually been integrated into all aspects of urban planning and construction management, and various regions have promoted the construction of sponge cities to improve the city's ability to use, store, and absorb rainwater, and promote the formation of a healthy circulating urban water system.
By the end of 2020, more than 40,000 projects have been built to implement the concept of sponge city construction across the country, which has improved the capacity and comprehensive utilization of rainwater resources, and realized the annual utilization of rainwater resources of 350 million tons.
——The concept of saving runs through, improving the mechanism to save water.
Sewage resource utilization experiments enter the campus, visit the water purification process... During this year's urban water conservation publicity week, various publicity activities were carried out in various places.
According to reports, in recent years, my country has actively carried out the creation of water-saving cities, promoted the introduction of water-saving concepts, water-saving methods, and water-saving tricks into communities, forming a green development method and lifestyle.
At present, 130 cities across the country have been established as water-saving cities. The total water consumption of these cities accounts for 58.5% of the total urban water consumption in the country, which has strongly promoted the national urban water-saving work.
"Continue to do a good job of urban water conservation with new ideas and new ideas, and we must use administrative, legal, economic, technical and other means to strengthen the supervision and management of water use behavior, and realize the transformation from extensive water use to conservation and intensive water use. "The person in charge said that this year is the first year of the "14th Five-Year Plan" and will fully implement the new development concept, further enhance the system of urban water conservation, and promote urban water conservation throughout the entire process of planning, construction, and management to achieve urban High-quality development.
