Ministry of Housing and Urban Construction National Development and Reform Commission on further strengthening the city\'s water conservation work
      [Abstract] Department of Housing and Urban Development and Reform Commission jointly issued the city of [2014] No. 114 overall idea proposed flood control: water conservation priority, spatial equilibrium, the system of governance, hands force. That "strictly control access to fresh water ecological landscape, rainwater, recycled water and building water use requirements, and the China Architecture Design Institute Limited National Standard editor of" civil-saving design standards "in government documents referenced centralized life hot water system requirements, does not meet the requirements for rectification.
      Provinces, autonomous regions and Construction Department of Housing and Urban Development and Reform Commission, municipalities, municipalities and Rural Construction (Municipal Committee, Water Authority), Development and Reform Commission, Hainan Provincial Office of Water Services, Bureau of Xinjiang Production and Construction Corps Development and Reform Commission:
       Urban water conservation is to solve the contradiction between supply and demand of water resources, improve water environment carrying capacity of urban water security issues to deal with important initiatives to support the implementation of the new urbanization strategy and building a socialist ecological civilization is important. The State Council attaches great importance to urban water conservation work. Xi Jinping, general secretary of the recent call by the construction of water-saving cities in depth, so that water conservation has become every unit, every family, every people's initiative. "State Council on strengthening urban infrastructure opinions" (Guo Fa [2013] No. 36) proposed to accelerate the construction of water-saving city. To implement the central spirit, practice water conservation priority, spatial equilibrium, the system of governance, the force of the flood-handed ideas, make full use of urban planning, construction and municipal public management and service platform to promote urban water conservation work, are notified as follows:
First, strengthen the leading role of water conservation planning. Overall urban planning should be scientific assessment of urban water resources carrying capacity, adhere to the water to the city, with water to land to water to people, to the principle of water quotas, overall water supply, water, drainage, sewage treatment and recycling, and water security, water ecology and coordinated water environment. Urban waste water pipes to first live, strictly control access to fresh water ecological landscape, made rainwater, recycled water and construction requirements for water use and other coastal cities to local conditions make water desalination water use requirements; according to favor water cycle, the principle of progressive utilization, layout municipal utilities; clear blue line control of the city, strengthen the protection of river and lake water. Preparation of regulatory detailed planning to clear the water conservation binding targets. To the detailed planning of the cities on the basis of the overall urban planning and controlling urban water conservation prepare special plan, put forward practical goal, from the water supply and demand balance, and the potential of mining, the countermeasures proposed the management mechanisms, measures and a detailed implementation plan, and with the urban water supply, drainage and sewage treatment, green, water and other planning phase of convergence.
Second, the strict implementation of water conservation, "three simultaneous" system. New construction, renovation and expansion of the construction of water-saving facilities with the main project must be designed, constructed and put into use. Urban development (urban water conservation) authorities to take the initiative to cooperate with relevant departments, in urban planning, construction design review, project construction, supervision, final acceptance and other management areas to strengthen the implementation of the "three simultaneous" system.
Third, greater efforts to control the water supply pipe network. To guide the city to speed up the renovation of the useful life of more than 50 years and the material behind the water supply network to ensure that the public water supply network leakage rate of the national standards. Urge water companies through the pipe network separate partition measured approach to strengthening leakage control and management, supervision and water users regularly carry out water balance test, and control of "leaking."
Fourth, vigorously promote low-impact development and construction mode. Developed into a piece of land should vigorously promote the construction of permeable pavement and sunken green space, through rainwater harvesting, permeable area, and other ways to increase control surface runoff. New Town hardened ground, the permeable surface area ratio of not less than 40%; conditional area to respond to existing hardened permeable pavement gradually transform and improve stormwater infiltration capacity. With urban water systems and local distribution of natural water resources, wetland restoration to take local conditions, interception, river dredging and other ways to improve urban water ecology. In accordance with the minimum impact on the urban ecological environment construction concept development, control the development of strength, minimizing damage to the aquatic environment of the original city, building a natural accumulation of natural infiltration, natural purification of "SpongeBob city."
Fifth, speed up the sewage recycling. The wastewater recycling as an important measure to reduce pollution load and improve the water quality of the environment, the rational distribution of sewage treatment and recycling facilities, in accordance with the "gifted with excellent water, the nearest use" principle, in industrial production, urban greening, road sweeping vehicles rinse, construction and other areas of ecological landscape priority use of recycled water. Water resources per capita is less than 500 cubic meters / year and the poor condition of the water environment areas, to reasonably determine the scale of renewable water use, to develop safeguards to promote the use of recycled water.
Sixth, actively promote the construction of water use. Extensive green building initiatives to encourage the use of residential buildings in the water, laundry, bathing and living miscellaneous other pollution lighter gray water collected and, after appropriate treatment, sequential used for flushing, water efficiency. Civil single building area over 20,000 square meters of public buildings, conditional area of affordable housing and other government investment should the construction of water facilities.
Seven, according to local conditions to promote the use of desalination water. Encourage plaque coastal freshwater resources and mining enterprises to carry out the lack of regional water use demonstration desalination, desalination of water will give priority to industrial production and cooling water. In related indicators meet the requirements to ensure that human health and the premise, to carry water into the municipal water system desalination pilot, improve the relevant norms and standards.
Eight, strengthen planned water and quota management. To combine the characteristics of the local industrial structure, strict implementation of the relevant provisions of the relevant national water standards and quotas. Water users grasp the planned water management plan scientifically determine the amount of water, water, water withdrawals owned water management plan should be included in the scope. To establish an information sharing mechanism and water supply enterprises to achieve real-time monitoring. Areas where conditions permit to build urban water supply network digital control platform, supporting water conservation.
Nine, vigorously carry out water-saving residential units, business development. In accordance with the national water-saving city assessment criteria, such as water-saving enterprise evaluation standards, carry out a comprehensive water-saving residential areas, water-saving units, water-saving enterprise-building activities, so that water conservation has become every organization and family everyone's initiative. To establish and improve local conditions around the water-saving incentives to encourage and support enterprises, positive selection of water-saving household appliances to accelerate the transformation of the state to update and utensils out of the water consumption; civil centralized hot water system should be in accordance with the national "civil water-saving design standards "required to take the water cycle measures to reduce water waste, water outflow time it invalid shall comply with the relevant provisions of the standard does not meet the requirements to be a deadline to complete the transformation.
Ten, strengthen the organization and leadership. To develop and improve urban planning, construction and municipal utilities aspects of water-saving system, methods and specific criteria in order to create water-saving city as the starting point, increase urban water conservation work to guide efforts to improve urban water conservation data reported to work. Urge the city government will build a water-saving cities to improve the living environment as an important foundation for the work, to co-ordinate the deployment, increase investment, and improve safeguards to form long-term working mechanism. Full use of the "World Water Day", "National Urban Water Conservation Awareness Week", "Energy Awareness Week" and an opportunity to vigorously carry out urban water conservation advocacy, mobilization of the people involved. Encourage and guide social capital to participate in water-saving diagnosis, water balance testing, infrastructure improvement, and other professional services.
