Background: Water safety plan is a systematic approach to ensure the quality of water delivered to consumers from catchment to consumption. Methods: This study was conducted on the groundwater system of Talesh, Gilan, in ۲۰۲۰-۲۰۲۱. A Water Safety Plan (WSP) consists of ۵ phases and ۱۲ steps. In the implementation of this plan, all modules were reviewed. Software checklists were prepared and based on the background information in Talesh Water and Wastewater Company, interviews with experts and field visits were performed, and then, entered into WSP QA TOOL software. Results: Out of ۴۴۰ raw scores, ۲۲۲ points were obtained, indicating ۵۰.۴۵% compliance with WSP. The description system with the highest score (۱۰۰%) and the management procedures with the lowest score (۵۰%) were in line with this plan. The stages of development and supporting program and review of WSP cannot be evaluated due to the incomplete implementation of water safety plan in Talesh. Between different parts of the water supply system, more attention has been paid to production sources and points of use. Conclusion: This study identifies the inefficiency in dependence on the final tests and the necessary items in updating the supply system of Talesh. According to the study of the different stages of WSP, the system has a moderate level of safety.
