Abstract
[Objective]Thoroughly implement the national standard Hygienic Specification for Facilities of Secondary Water Supply(GB 17051-2025),which will come into effect on June 1,2026,to advance the standardization of daily management tasks such as operation,maintenance,cleaning,and disinfection of secondary water supply facilities,and to ensure the safety of the final segment of the residential water supply chain.[Methods]Analysis and discussion on the major impacts and roles after the release of Hygienic Specification for Facilities of Secondary Water Supply(GB 17051-2025),including an examination of standard positioning,selected terms and definitions,design capacity of water tanks(pools),installation requirements for disinfection equipment,and water quality testing requirements;with analysis and discussion on the renovation and management takeover of secondary water supply facilities,water quality testing,and water quality work orders in Shanghai.[Results]Hygienic Specification for Facilities of Secondary Water Supply(GB 17051-2025)helps standardize the daily operation and management,renovation and construction,and emergency response to incidents involving secondary water supply facilities.The paper proposed several recommendations for Shanghai's implementation of the standard,including accelerating the handover of secondary water supply facilities to water supply enterprises,advancing research on improving pressurization method for secondary water supply,expediting the development of categorized plans for ensuring water quality during emergencies,and formulating practical water quality testing protocols.[Conclusion]Hygienic Specification for Facilities of Secondary Water Supply(GB 17051-2025)further strengthens the operational requirements for secondary water supply facilities,which is of great significance for improving the management level of operating entities and ensuring the safety of residents'drinking water.However,some aspects of the standard may not be sufficiently comprehensive,which can affect its implementation effectiveness.Shanghai has about 115 000 water tanks(pools)in residential communities,making it the city with the largest number of secondary water supply facilities in China.When implementing the national standard,it is recommended to fully consider Shanghai's actual conditions and adopt a combination of key investigations and sampling surveys to carry out water quality testing for secondary water supply systems.关键词
