Introduction: The water safety plan is a systematic approach that aims to ensure the quality of water distributed to consumers. In ۲۰۰۴, the World Health Organization issued a statement implementing the water safety plan. The plan is underway in Iran. The purpose of this study is to review the studies conducted from ۲۰۰۴ to ۲۰۲۰. Materials and Methods: Present article is a systematic review study to search for keywords in a combination of "water safety plan" (WSP), "Iran", "Hazard Analysis and Critical Control Points", (HACCP) and "water" in international databases including: PubMed, Science Direct, Google Scholar, as well as national databases include: Magiran and SID. Results: In the initial search, ۶۷۱ articles were found that after screening based on the Prisma checklist, ۱۵ articles were included in the study for further review. The results showed that in the implementation of WSP, the highest score is related to Qom city with ۶۸.۶۴% and the lowest value is related to Khoy city with ۱۷.۵%. Improvement and upgrade program, support program development, and review of WSP courses have received less attention. Low staff familiarity with WSP, insufficient team composition and lack of coordination between them in holding regular meetings can be the reason for poor implementation of WSP in Iran. Conclusion: The full implementation of the water safety plan controls the risks in the water supply system and reduces costs, as well as improves and increases the quality of water distributed to consumers.
