| Abstract | Consumption of unsafe water particularly in developing countries resulted in considerable the amount of illness and death annually. Many water supply services have relied on end testing of drinking water quality, however, this traditional approach crates too little and too late for any preventive action. The World Health Organization is promoting the theory of water safety plan (WSP) to consistently ensure the safe of drinking water, based on comprehensive risk assessment approach. The aim of this study is to carry out the development of WSP, which includes hazard identification, hazardous event, as well as risk priority from the catchment to end-user in Vientiane City, Lao PDR. Data was collected through field observations, interview key persons, household’s questionnaire and its water quality analysis (turbidity, conductivity, pH, and residua l chlorine). Risk priority and risk matrix approach (semi-quantitative matrix) were provided for data analysis. The results of risk priority presented that 26 of 46 hazardous events could be considered as high and very high risk ratings. Those hazardous events needed to be considered the alternative sources and control measures in order to protect, to treat and to reduce, and to prevent efficiently all contamination points from the catchment to end-users. In term of water quality analyses at household’ stage, four important parameters were totally followed up both national standard and NPNL self-standard. 82% residual chlorine was equal or greater than 0.2 mg/L. Nonetheless, 9 of 10 water samplings in storage tanks had no residual chlorine or less than 0.2 mg/L. |
