The scientific field of this project is environmental medicine. It has explored and established a supervision model that is in line with the characteristics and laws of Shanghai's super-large urban drinking water supply systems. It has made more use of information technology such as the Internet and big data to gradually improve the scientific supervision and management of drinking water sanitation., refined and intelligent level ensures that the entire city's drinking water from the entire process of water source, water production, water supply, and water use, as well as from centralized water supply, The hygiene and safety of drinking water in various forms of water supply, from secondary water supply to ready-made and ready-sold drinking water, are at the leading level in the country. 1. Optimize and upgrade the drinking water supervision, early warning and control platform, create a comprehensive drinking water supervision and information service platform (hereinafter referred to as the information platform), and use this as an important basis for promoting the implementation of this project. 2. Guided by the unique ldquo; Internet +rdquo; thinking concept of continuous pursuit of innovationrdquo;, promote the construction of drinking water legal standards, and use this as an institutional guarantee for promoting the implementation of this project, mainly including the completion of the formulation of government regulations "Shanghai City Measures for the Supervision and Management of Domestic Drinking Water Hygiene" and local standards "Domestic Drinking Water Hygiene Management Standards" and "Domestic Drinking Water Quality Standards". 3. Relying on the information platform, establish data sharing with industry authorities based on data standards in the field of centralized water supply, and explore information-based risk management of centralized water supply units, mainly including realizing electronic data with water departments. Sharing and exploring risk rating and risk management using centralized water supply units as examples. 4. Relying on the information platform, promote social co-governance and comprehensive management in the field of secondary water supply, explore strategic cooperation with managed persons, and promote social supervision, mainly including organizing health and family planning supervision agencies to sign ldquo; strategic cooperation agreement rdquo;, as well as carrying out secondary water supply information disclosure based on QR code, and promoting third-party supervision of secondary water supply cleaning and disinfection. 5. Relying on the information platform, carry out joint law enforcement and precise supervision based on information sharing in the field of freshly produced and sold drinking water, including carrying out information disclosure on hygiene management of freshly produced and sold drinking water, and on this basis, the health and urban management departments of the company jointly implement ldquo; precision rdquo; law enforcement 6. Relying on the information platform, improve the capacity building of the drinking water sanitation supervision team. The project has been built and applied in the past five years, and has achieved useful verification in various fields such as daily hygiene supervision and management of drinking water in the city, handling of complaints and reports, and drinking water hygiene safety for major events. In five years, on the basis that the overall number of drinking water hygiene supervisors in the city has basically remained unchanged, the city's drinking water quality pass rate has increased from 95% to 98.8%, and the health supervision and management pass rate has remained stable at above 95%. Drinking water hygiene The efficiency of supervision has been improved, effectively ensuring the hygiene and safety of the city's drinking water. There has been no sudden pollution incident of drinking water in the city in five years. It has made important contributions to urban economic construction and stable operation. The results of this project are not only applied in various fields such as daily drinking water sanitation supervision and management. Relying on this project, information sharing, business docking, exchanges and cooperation have also been established with government departments (such as the Water Affairs Bureau and the Water Supply Dispatch and Monitoring Center), industry management units (such as Shanghai Urban Investment (Water) Group Limited), sister units (health supervision agencies in Jiangsu, Tianjin and other provinces and cities, health supervision agencies at all levels in the city), and foreign research institutions (Deltares, the Netherlands), etc. Representatives of the project team went to the Netherlands, the Czech Republic, Croatia and Germany for international exchanges, providing reference for the supervision of drinking water by health and family planning supervision agencies in Shaanxi, Guangxi, Hainan and other provinces and cities, and published 22 related papers. Relevant content of the project has won the third prize of Shanghai Medical Science and Technology Award and the third prize of Shanghai City Preventive Medicine Science and Technology Award.
