first, set the reasons
urban drainage and sewage treatment are important components of municipal utilities and urbanization. in recent years, china's urban drainage and wastewater treatment industry has made great progress, but there are also some outstanding problems: first, the construction of urban flood drainage infrastructure is lagging, and heavy rain disasters occur frequently. in some places, there is a lack of overall planning for urban infrastructure construction, “emphasizing ground and light underground”, focusing on emergency disposal, prevention at light level, lack of support for construction, low standards, unbalanced ratio of hardened ground and pervious ground, and poor township drainage capacity construction lags behind towns. rapid expansion of scale. second, the behavior of sewage discharge is not standardized, and the operation safety of facilities cannot be guaranteed, which will affect public safety in cities and towns. at present, in terms of urban drainage, there is no corresponding legislation at the national level. some drainage households have exceeded the standards and discharged industrial waste, construction slurry, restaurant fats and oils, and medical sewage directly into the pipe network without affecting the pipe network and sewage treatment. factory operation safety and urban public safety. third, the operation and management of the sewage treatment plant is not standardized, and the sewage sludge treatment and treatment compliance rate is low. some sewage treatment plants have stolen or excessively discharged sewage, dumped or dumped the sludge without authorization, or did not dispose of the sludge as required, causing secondary pollution. fourth, government supervision is not in place and accountability is not clear. the government departments are not in charge of the supervision of drainage and sewage treatment, and there is no clear regulation on the accountability of the state staff who do not fulfill their statutory responsibilities and the legal liabilities of the drainage households and other subjects. in order to solve the above problems, it is necessary to formulate the "regulations on urban drainage and sewage disposal" to include urban drainage and sewage treatment in the rule of law.
second, overall consideration
china is in an important period of industrialization and urbanization. the overall considerations in the formulation of regulations are as follows: first, the development of urban construction and town drainage and wastewater treatment should be coordinated. urban drainage and sewage treatment planning should be based on the level and objectives of urban development, and be linked with the special plans. the construction of the new area will be implemented with rain and sewage diversion, while reconstruction of old areas and road construction shall simultaneously reform the combined rain and sewage. the second is to prevent and treat urban water pollution and promote the comprehensive utilization of resources. use rainwater collection and utilization facilities such as buildings, parking lots, and plazas to encourage recycling of wastewater. the third is the combination of drainage management and safeguarding facilities. we will standardize the discharge of rainwater and sewage, strengthen the maintenance and protection of facilities, and ensure the safe operation of facilities and public safety in cities and towns. the fourth is to establish a mechanism for preventing and controlling early-warning, consultation, and linkage of internal guilt and strictly control responsibilities. the local government organizes emergency preparedness plans, makes overall arrangements for the discharge of waste materials, strengthens the management of easy points, and works together to prevent and treat internal hail. the fifth is to clarify the regulatory responsibilities and strengthen accountability. in accordance with the principle of the right to be responsible, the supervisory duties of the government and its related departments and the accountability of non-fulfilment of supervisory duties shall be strengthened. sixth, do a good job in connection with the flood control law, flood prevention regulations, and river management regulations. local governments have stepped up the construction and renovation of facilities to give full play to the flood discharge capacity of the rivers, and adopted dredging and dredging measures to ensure smooth drainage. flood prevention command agencies must step up inspections at easy points to eliminate dangerous situations in a timely manner.
third, ensure that the government invests in and attracts social funds
the "opinions of the state council on strengthening urban infrastructure construction" issued in september 2013 proposes that, on the basis of safeguarding government investment, the role of the market mechanism should be brought into full play, reform of the investment and financing system and operating mechanism should be promoted, and a city with a rational division of labor between the government and the market should be established. the infrastructure investment and financing system encourages social funds to participate in the construction of urban infrastructure. in order to ensure the government's investment, the regulations clearly require local people's governments at or above the county level to increase investment in the construction and maintenance of urban drainage and sewage treatment facilities in accordance with the requirements of urban drainage and sewage treatment planning. at the same time, it also stipulates that the state encourages franchising, government procurement services, and other forms to attract social funds to participate in investment, construction and operation of urban drainage and sewage treatment facilities in order to give full play to the market mechanism.
fourth, to solve the system of waterlogging and other internal disasters
the regulations stipulate a series of institutional measures in response to urban disasters. the first is to make provisions from the planning level, requiring cities and towns that are prone to infighting to formulate special plans for the prevention and control of urban internal disasters, and include urban drainage and wastewater treatment plans in their respective administrative regions. the compilation of special plans for prevention and control of urban floods shall be based on factors such as urban population and scale, rainfall patterns, risk of internal storms, and other factors, reasonably determine the objectives and requirements for internal control, make full use of natural ecology, and improve the ability of rainwater stagnation, storage and discharge. second, it is stipulated that municipal infrastructure projects should be equipped with rainwater collection and utilization facilities to increase the ability of green spaces and permeable pavements to stop seepage of rainwater. in the construction of new areas and reconstruction of old urban areas, relevant facilities should be constructed in accordance with the requirements of stormwater runoff control. the third is to provide relevant departments and units of local government organizations to prepare contingency plans, establish mechanisms for preventing and controlling early-warning, consultation, and linkages of internal hemorrhoids, make overall arrangements for drainage materials, strengthen the management of easy points, and work together to prevent and treat internal hemorrhoids; strengthen facilities construction and transformation, and give play to the flood capacity of the rivers should be dredged and dredged to ensure smooth drainage. in the flood season, the flood control headquarters should strengthen the inspection of the easy points and eliminate the danger in time.
v. facilities construction system measures
scientific and rational planning is an important guarantee for effectively guiding the construction of urban drainage and sewage treatment facilities. therefore, the regulations attach great importance to the guiding and controlling functions of planning, strictly follow the principle of “pre-planning and post-construction,” and specialize in “planning and construction”. chapter regulations. first, the state council’s housing and urban-rural development department shall work with the relevant departments of the state council to formulate a national plan for urban drainage and sewage treatment. the local municipal and municipal drainage authority shall, in conjunction with relevant departments, compile the towns of the administrative region according to local economic and social development levels and geographical and climatic characteristics. drainage and sewage treatment planning, and clear planning approval and modification procedures. second, in accordance with the principles of overall planning and supporting construction, it is explicitly required that local governments should reasonably determine the standards for the construction of urban drainage and sewage treatment facilities in accordance with the plan, and make overall arrangements for pipeline networks, pumping stations, sewage treatment plants, sludge treatment and disposal, and rainwater storage and storage. emissions and other drainage and sewage treatment facilities construction and transformation. the third is to stipulate that the land for facility construction determined by the urban drainage and wastewater treatment plan shall not be used without authorization; for the development and construction of a new urban area, priority shall be given to the construction of drainage and sewage treatment facilities in accordance with the construction sequence determined by the plan. fourth, the new construction, reconstruction, expansion and construction projects are required. the construction unit should construct a drainage connection pipe network as required. fifth, after the completion of construction projects for urban drainage and sewage treatment facilities, the construction unit shall organize the acceptance inspection according to law. acceptance after completion of the project can be delivered for use.
6. strengthen the provisions for the maintenance and protection of manhole covers and other facilities
in order to strengthen the management of manhole and other facilities, the regulations have made four provisions: first, manhole covers on the roads of motor vehicles should be constructed in accordance with regulations, and their bearing capacity and stability should be related. the second is that the manhole cover should have anti-dropping and anti-theft features to meet the structural strength requirements. third, urban drainage and wastewater treatment facility maintenance and operation units should strengthen daily inspections, maintenance and conservation. fourth, in the maintenance of pipelines and other operations, special personnel should be arranged to conduct on-site safety management, set up striking warning signs, and take effective measures to prevent people from falling, vehicles falling into place, and promptly rehabilitate the covers.
vii. regulations for strengthening the discharge of rainwater and sewage
the strengthening of management of rainwater and sewage discharges is an important guarantee for ensuring smooth drainage, facilities safety, and public safety in cities and towns. it is also an important means for ensuring urban sewage discharge standards and prevention and control of water environmental pollution. the regulations made two provisions: it is to strengthen management of stormwater discharge. the local government should establish a geography information system for drainage facilities. the drainage department should determine the standards for the construction of rainwater collection and utilization facilities to ensure that the discharge of rainwater is unimpeded in accordance with the special planning requirements for urban flood prevention and control; the rainwater and sewage diversion areas must not discharge sewage into the rainwater pipe network. the second is to strengthen the management of sewage discharge. drainage units and individuals within the coverage areas of urban drainage facilities shall discharge the sewage into urban drainage facilities in accordance with relevant state regulations. sewage discharged from enterprises, institutions, and individual industrial and commercial enterprises engaging in industrial, construction, catering, medical and other activities shall be pretreated and meet relevant requirements. the drainage monitoring agency shall monitor the quality and quantity of discharged sewage. at the same time, the regulations also stipulated corresponding legal responsibilities for illegal discharge.
viii. system measures to ensure the safe disposal and disposal of sludge
in order to solve the problems existing in the current practice such as the low rate of sludge harmless treatment, the rational and effective use of less channels, and the secondary pollution caused by arbitrary disposal, the regulations clearly stipulate that the urban sewage treatment facility maintenance and operation units or sludge treatment and disposal units shall safely dispose of the sludge and ensure that the treated sludge complies with relevant national standards, and track and record the generated sludge, and the destination, usage, and dosage of the treated sludge, and report it to the drainage department and the environmental protection department. no unit or individual may dump, stack, discard, or leave behind sludge. at the same time, the regulations also stipulated corresponding legal responsibilities for the illegal handling of sludge.
ix. provisions to promote the recycling of sewage
the recycling of urban sewage is an important way to promote urban water-saving emission reduction and improve the living environment. the "opinions of the state council on strengthening urban infrastructure construction" issued in september 2013 proposes that by 2015, the utilization rate of reclaimed water from urban sewage treatment facilities will reach over 20%. in order to promote the recycling of sewage, the regulations stipulate the following six aspects: first, the government at or above the county level shall be required to encourage and support scientific research on urban drainage and wastewater treatment, and promote the use of advanced and applicable technologies and processes to promote the recycling of sewage. the second is to treat sewage treatment and recycling as an important part of local urban drainage and wastewater treatment planning. third, it is stipulated that local governments should make overall plans for the construction and reconstruction of facilities such as the use of recycled water. fourth, the state shall encourage the reuse of recycled water for sewage treatment, industrial production, urban greening, road cleaning, vehicle washing, construction and ecological landscape. fifth, it is stipulated that the local government should reasonably determine the scale of reclaimed water use based on local water resources and water environment conditions, and formulate safeguard measures to promote the use of recycled water. sixth, the reclaimed water shall be included in the unified allocation of water resources, and local water administrative departments shall strengthen guidance according to law.
