- Abstract:
- The secondary water supply is called the “Last kilometer” of the urban water supply, which has a vital influence on the safety of the urban water supply. Although all levels of government attach great importance to it, but the actual control situation of the secondary water supply is not optimistic. There are a series of issues in the secondary water supply system in Hunan Province, such as the low construction standard of the secondary supply system, the non-standard operation and maintenance management, the serious leakage of the pipeline network, and the difficulty in ensuring the water quality and safety, etc. So it is of great practical significance to compile the Technical Standard for Urban Secondary Water Supply Facilities in Hunan Province. The standards are guided by the concepts of high standards, strict requirements, landing, product lifecycle management, and leading the healthy development of the industry. The design of the secondary water supply system, the selection of equipment and materials, the construction of the project, the debugging and acceptance, and the operation maintenance and management are formulated in detail. The standards provide important technical support for the construction and management of the secondary water supply system in Hunan Province.
