摘　　要：二次供水被称为城镇供水的“最后一公里”,对城市供水安全有着至关重要的影响。尽管各级政府对其高度重视,然而实际管控情况并不乐观。湖南省二次供水系统存在建设标准偏低、运维管理不规范、管网漏损严重、水质安全难以保障等一系列问题,因此编制《湖南省城镇二次供水设施技术标准》(DBJ 43/T 353—2020)具有重要的现实意义。该标准以高标准、严要求、可落地、全生命周期管控、引领行业健康发展的理念为指导,对二次供水系统设计、设备与材料的选择、工程施工、调试与验收、运维管理等环节进行了详细规定,为湖南省二次供水系统的建设与管理提供了重要的技术支撑。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.
