Background and Objective: One of the main ways of transmitting diseases is drinking water, so the safety of drinking water is an important issue for consumers, water suppliers, operators, and health officials. This study was conducted to identify and semi-quantitative evaluation and prioritization of risks in the drinking water supply system of Bostan Abad city.
Materials and Methods: In order to evaluate and document the key elements of WSP and identify the steps that need improvement, the quality assurance tool of the water safety plan (WSP-QA TOOL software) was used, and then based on the guide of the water safety plan from the WHO and the International Association Water safety, WSP team formed. Then the water supply system of Bostan Abad city from the farthest point of the basin to the last consumption point was inspected and described.
Results: The results showed that the highest number of risks are in the water supply sources, distribution network, and point of consumption, respectively. Also, the most vulnerable part of the system was identified as the disinfection unit and storage tanks due to biological and chemical contamination caused by equipment failure and improper preparation of chlorine solution.
Conclusion: In summary, it can be said that carrying out the necessary reforms can play an effective role in reducing the risk potential in times of crisis, which should be given serious attention by water industry officials.
