Abstract: With the continuous deepening of ecological civilization construction in China, the urban water systems tend to collaborative governance, coordinative promotion in the "14th Five-Year Plan" period. Given the common problems of urban water system operation and management, such as inadequate systems, imperfect standards, low operational quality and efficiency, and difficulties in promoting experience and making use of data and other issues, we sorted out the operation logic based on business scenarios, reconstructed the operation process based on digital features, explored the implementation path of intelligent operation of the urban water system, constructed the top-level design of the intelligent operation of the urban water system based on the asset with systematic thinking, and clarified the core elements and key links, and developed the intelligent operation platform for the deep integration of environmental protection operation and information technology. By constructing a full-process operation management workflow consisting of "information collection, asset assessment, hierarchical maintenance, refined management, monitoring and early warning, and comprehensive scheduling", it provides new ideas for realizing the long-term operation of urban water systems, and promotes urban water system standardization, refinement, intelligent operation, and creates long-term value for the ecological environment.
