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 2020-2021. A Water Safety Plan (WSP) consists of 5 phases and 12 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 440 raw scores, 222 points were obtained, indicating 50.45% compliance with WSP. The description system with the highest score (100%) and the management procedures with the lowest score (50%) 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.
Introduction: The water safety plan is a systematic approach that aims to ensure the quality of water distributed to consumers. In 2004, 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 2004 to 2020.
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, 671 articles were found that after screening based on the Prisma checklist, 15 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 68.64% and the lowest value is related to Khoy city with 17.5%. 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
