Abstract
The transfer of water from the source to the consumption point is always associated with the possibility of contamination in any of its various components. To resolve this problem, the World Health Organization has considered a water safety plan. The purpose of this study is to implement water safety plan in the water supply system of Bukan city. This study was performed on Bukan’s water supply system in 2019–20 using a software to guarantee the quality of the water safety plan and the WHO and IWA guidelines. The software checklists were prepared and after confirming the validity of the translation and its facial and content validity, it was completed based on the records of the Water and Sewerage Company and interviews with experts. Out of a total of 440 points of full-application of the program and 392 points for the reviewed phases, 183.6 points were acquired and 43.7% of WSP-coordinated implementation was observed. The highest percentage of WSP-coordinated implementation (75.2%) was assigned to the validation stage with the highest point, and the support program stage had the lowest percentage of performance (1.1%). Among the major components of the water supply system, the final consumption point received the most attention from the system. Given the lifespan of the introduction and use of WSP in the world, it was expected that better results would be obtained from evaluating the implementation and progress of this approach in Bukan’s water supply system. However, the implementation rate of this program in this city compared to other cities in Iran, showed that according to the implementation time (one year), the obtained results are relatively convincing and good and the water supply system has a moderate level of safety.

Summary
All living things on earth need water to survive [1]. Providing safe water today is one of the most important human challenges in societies, especially in developing countries [2, 3]. The Water safety plan has been written and prepared by the World Health Organization and the International Water Institute in the third and fourth editions and it is a powerful tool to reduce risk and prevent water pollution from the catchment area to the point of consumption [14]. This program has been designed to manage health hazards that could threaten water resources. Preventive risk management requires that the risks associated with safe drinking water safety be identified, prioritized, and protected the drinking water quality before problems occur [15]
