Abstract
The traditional technique for management potable water quality is not an appropriate preventive approach for protecting public health. The Water Safety Plan (WSP) introduces a systematic plan to ensuring the health and quality of potable water. The aim of present study is to compare the performance of water safety plans in several countries. WSP is implemented in 10 countries, including USA, China, France, Palestine, Indonesia, Syria, Iceland, Italy, Uganda, and Iran. Findings showed that microbial contamination in catchment, discharge waste of humans, birds, animals, and domestic waste in water sources, fluctuations of free residual chorine in point of use, lack of manpower training and financial resources, insufficient documentation system, and old infrastructure were identified as the most important barriers. The major benefits of WSP implementation were control of the risks in the water supply system and decrease of expenditures, increase of satisfaction customers, effective coordination and monitoring, improvement in treatment processes, reduction of water borne diseases, improvement of water quality and safety of potable water, and improvement of public health. The results of the present study can help researchers, policy-makers, health decision-makers, and people improve water quality of drinking water and improve public health.
