Is the existing investment sufficient? How does the "Ten Rules for Water" affect the water environment?
The investment demand for urban water supply, drainage and waterlogging prevention, sewage treatment facility construction, transformation, operation and maintenance is about 800 billion yuan per year, and there is a huge demand for funds at present; We must attach great importance to the protection of water security, water environment and water ecology.
From the perspective of the investment and charges of tap water, the fixed asset investment in urban water supply in China has reached 68.9 billion yuan, accounting for 3.4% of the total social fixed asset investment in municipal utilities. The annual collection of tap water fees amounts to about 67 billion yuan. From the perspective of investment sources, at present, China's urban water affairs mainly rely on government financial investment and bank loans.
From the perspective of investment and charges for sewage treatment, in 2013, the fixed asset investment in urban sewage treatment in China reached 105.5 billion yuan, accounting for 5.2% of the total social fixed asset investment in municipal utilities, and the annual collection of urban sewage treatment fees reached 23 billion yuan.
According to the prediction that the urbanization rate will increase by 0.8%~1.0% every year (equivalent to 10~13 million new urban population), the water supply and drainage network in China needs to reach 23000 km, the water supply capacity needs to reach 3.6 million tons/day, the sewage treatment capacity needs to reach 2.5 million tons/day, and the investment in new facilities needs about 50 billion yuan every year.
According to domestic and foreign studies, the reasonable investment in urban water supply, drainage and waterlogging prevention, sewage treatment facility construction, transformation and operation maintenance should be 1.5% of GDP. Based on this, China's annual investment is at least 800 billion yuan. At present, China's annual investment in this field is only 110~130 billion yuan, and there is a huge demand for funds.
What positive impacts will the forthcoming "Ten Rules for Water" have on the water environment?
With the continuous improvement of China's urbanization rate, the urban water supply guarantee ability, flood prevention level, and resource and environmental capacity are facing greater and greater challenges.
In the face of the increasingly prominent situation of water resource shortage, serious water pollution, water ecological degradation and other problems in some cities and towns in China, the "Ten Rules for Water" will be issued soon. The state requires to build a scientific and reasonable urbanization layout according to the carrying capacity of resources and environment; Minimize the interference and damage to nature, and economize and intensively use land, water and energy resources; To solve the problem of urban water shortage, we must conform to nature and build a "sponge city" with natural accumulation, natural infiltration and natural purification. The Ministry of Housing and Urban Rural Development has also issued relevant technical guidelines and standards to support the construction of sponge cities.
In the next step, we need to take various measures to speed up the construction of urban water supply security system, flood control and drainage system, and ecological space system, so as to achieve the goal of supporting sustainable economic and social development and ensuring a virtuous cycle of water ecological environment.
