Abstract: The healthy and safety situation of swimming places have been improved significantly through the supervision mode, which mainly combines quantitative classification-based management, the combination of regular supervision and dual random supervision, the combination of online monitoring and on-site detection of water quality, and the combination of separate law enforcement and multi-department joint law enforcement. However, it shows limitations in laws and regulations of sanitation supervision, the power of sanitation supervision and law enforcement and technical support for sanitation supervision. Based on the background of credit system construction and policy support, the advantages of credit supervision, and the current status of sanitation credit supervision in public places, this paper discussed the necessity and feasibility of implementing sanitation credit supervision in swimming places, and demonstrated the important role of credit in improving swimming place supervision. We hope it can solve problems better in swimming place supervision, strengthen the honesty and self-discipline of supervisees, and enhance the effectiveness of sanitation supervision and law enforcement.
