Accelerate the formation of a new pattern of sewage collection and treatment and resource utilization

The National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development recently issued the "Fourteenth Five-Year Plan" Urban Sewage Treatment and Resource Utilization Development Plan. The "Planning" proposes to improve the quality of the water ecological environment and accelerate the formation of a reasonable layout , System coordination, safe, high-efficiency, energy-saving and low-carbon urban sewage collection and treatment and a new pattern of resource utilization.

The "Planning" proposes that by 2025, the direct discharge of domestic sewage and the blank area of ​​collection and treatment facilities in urban built-up areas will be basically eliminated, and the national centralized collection rate of urban domestic sewage will strive to reach more than 70%;

The sewage treatment rate in counties reaches 95% or more; the sewage treatment in sensitive areas of the water environment basically meets the level A discharge standard; the utilization rate of reclaimed water in water-deficient cities at prefecture-level and above in the country reaches more than 25%, and the Beijing-Tianjin-Hebei region reaches more than 35% In the middle and lower reaches of the Yellow River Basin, cities with water shortages at prefecture-level and above strive to reach 30%; the harmless disposal rate of urban sludge reaches more than 90%.

According to reports, in recent years, various regions and departments have vigorously promoted the construction of urban sewage treatment facilities, and the sewage treatment capacity and level have been significantly improved. However, the development of urban sewage treatment is unbalanced and insufficient. The sewage treatment capacity of some cities and more than 400 counties in the country cannot meet the demand, and about 40% of the established towns do not have the domestic sewage treatment capacity.

Promote the construction of urban sewage treatment and resource utilization facilities

The "Planning" also proposes that during the "14th Five-Year Plan" period, measures should be implemented in accordance with local conditions and classified, in accordance with the principle of government-led and market operation, and systematically promote the construction of urban sewage treatment and resource utilization facilities.

In terms of making up for the shortcomings of the urban sewage pipeline network, newly-added centralized sewage treatment facilities are simultaneously supporting the construction of a sewage collection pipeline network to speed up filling in the blank area of ​​the pipeline network. Carry out the diagnosis, repair and update of the pipeline network, promote the systematic rectification of the area, and promote the transformation of the pipeline network with mixed errors and missed connections in an orderly manner. During the "14th Five-Year Plan" period, 80,000 kilometers of sewage collection pipelines will be newly added and renovated.

In terms of strengthening the weaknesses of urban sewage treatment facilities, combined with urban development and simultaneous construction of treatment facilities, the scale of large and medium-sized urban facilities can be moderately advanced, and the construction of organic town facilities can be steadily promoted. The rapid purification facilities of combined overflow sewage will be built according to local conditions. During the "14th Five-Year Plan" period, the new sewage treatment capacity will be 20 million cubic meters per day.

In terms of resource utilization, systematically plan urban sewage recycling facilities, plan the layout of reclaimed water pipeline network in advance, and realize the quality and target water supply. Implementation of regional reclaimed water recycling projects. During the "14th Five-Year Plan" period, the newly built, rebuilt and expanded reclaimed water production capacity shall not be less than 15 million cubic meters per day.

In addition, it is necessary to speed up filling the gaps in sludge disposal capacity in cities and counties. During the "14th Five-Year Plan" period, the scale of newly-added non-hazardous sludge disposal facilities shall not be less than 20,000 tons per day.

Establish a diversified financial investment guarantee mechanism

In order to fully implement the "Fourteenth Five-Year" Urban Sewage Treatment and Resource Utilization Development Plan, safeguard measures have also been proposed in terms of finance, taxes and fees.

The "Planning" proposes to broaden the investment and financing channels for urban sewage treatment and resource utilization projects. Local people's governments at all levels must establish a diversified financial capital investment guarantee mechanism. Local government special bonds and funds from the central budget provide appropriate support to eligible projects. Guide social capital to actively invest. Encourage financial institutions to provide medium and long-term credit support. Actively promote the pilot projects of real estate investment trust funds in the field of infrastructure.

At the same time, improve the fee and tax mechanism. In accordance with the principle of covering the normal operation of sewage treatment facilities and the cost of sludge disposal and reasonable profitability, the sewage treatment fee standard shall be formulated reasonably. Before the sewage treatment fee standard is adjusted in place, subsidies should be given according to regulations. Liberalize government pricing of recycled water. Encourage the use of government procurement of services to promote the use of recycled water for ecological water replenishment.
