01 The Development Background of Urban Water Supply Construction

How to pool the wisdom and efforts of everyone to ensure that residents can drink "safe water"? The most direct way is to improve the water quality. And the most obvious experience is precisely the improvement of water quality. In order to better address the water quality safety issue in the "last mile" of urban water supply and guarantee the quality of domestic water, the "Notice of the General Office of the Ministry of Housing and Urban-Rural Development, the General Office of the National Development and Reform Commission, and the Comprehensive Department of the National Disease Control Administration on Strengthening the Work of Urban Water Supply Safety Assurance" requires that localities strengthen and improve the construction and management of secondary water supply facilities for urban residents, comprehensively and systematically enhance urban water supply work, promote the high-quality development of urban water supply, continuously enhance the ability to ensure water supply safety, and meet the growing needs of the people for a better life.

According to relevant policies, since April 1, 2023, urban water supply has fully implemented the Hygienic Standard for Drinking Water (GB 5749 - 2022). It is expected that by 2025, a relatively complete full - process urban water supply guarantee system and a basically sound urban water supply emergency system will be established.

By then, the water supply pipe networks in the built-up areas of the pilot cities (county towns) will be basically sound, with full coverage of the zonal metering of water supply pipe networks. The level of pipe network pressure regulation will reach the domestic advanced standard. A relatively complete operation and maintenance management system as well as a restraint and incentive mechanism for public water supply pipe networks will be basically established. Grid-based and refined management of water supply pipe networks will be realized, and a number of advanced models and typical cases of leakage control will be formed.

At present, for the built-up areas of pilot cities (county towns) where the leakage rate of public water supply pipe networks was higher than 12% in 2020, the leakage rate should be no higher than 8% by 2025. For the built-up areas of other pilot cities (county towns), the leakage rate should be no higher than 7% by 2025.

02 The Key Points and Problems of Urban Water Supply Construction

△ Promote the renovation of urban water supply facilities and strengthen the construction and renovation of water supply pipe networks.

It is strictly prohibited to use cement pipes, asbestos pipes, gray cast iron pipes without anti-corrosion linings and other materials that have been explicitly prohibited by the state, so as to ensure the construction quality.

Design the renovation plan for the aging water supply pipelines. For inferior pipes and pipelines that affect the water supply quality, endanger the water supply safety, and have serious leakage problems, as well as other pipelines that have been in operation for 30 years and pose potential safety hazards, expedite the renewal and renovation in combination with projects such as gas pipeline renovation, urban renewal, renovation of old residential areas, renovation of secondary water supply facilities, and the renovation of "one household, one water meter".

△ Implement the management and control of leakage in public water supply pipe networks and continuously reduce the leakage rate of water supply pipe networks.

Further enhance the management level of water supply pipe networks. Through measures such as zonal metering, pressure regulation, optimized dispatching, and intelligent management, ensure the safe, low-consumption, and energy-saving operation of the water supply pipe network system, and meet users' requirements for water quantity, water pressure, and water quality.

△ Promote the coordinated management of residential pressurization and storage facilities, and optimize and improve urban water supply services.

Establish a dynamic information update mechanism. Install emergency water supply interfaces on the inlet pipes of residential compounds and buildings that can be connected to external pressurization equipment such as water supply trucks, and further straighten out the management mechanism of residential water supply pressurization and storage facilities.

Continuously optimize and improve urban water supply services, enhance the level of intelligent water supply management, and promote the public disclosure of water supply information. On the premise of ensuring water supply safety, formulate simple and standardized water supply service processes according to local conditions, and clarify service standards and time limits.

Urban water supply is an important livelihood project, which is related to the physical health of the people and social stability. However, at present, the overall concentration level of the urban and rural water supply industry in China is still relatively low.

With the progress of the country's urbanization development and the cyclical changes in economic growth, the problems that are prevalent in domestic water supply pump houses across the country, such as facilities leaking, irregular water supply services, high risks of water quality pollution, idle water tank storage and regulation functions, and potential public security hazards, have made it increasingly prominent that domestic pump houses lack standardization, standardization and intelligence. The advancement of the renovation of water supply facilities in old urban and rural areas is facing a severe situation, and the demand for smart water services in the water industry has fallen short of expectations.
