Abstract

Water is a fundamental requirement for all life activities and is essential to humans, animals, and plants. Various physicochemical and bacteriological parameters can be used in assessing the quality of drinking water. This study was carried out according to the Sri Lankan Standards (SLS) and the standards set by the World Health Organization (WHO) for drinking water. Seven water samples were collected and selected physicochemical and bacteriological parameters were determined. The results indicated that all parameters of the chlorinated water were within the permissible levels of SLS, and WHO. Therefore, it can be concluded that the overall efficiency of the existing water treatment plant was at a satisfactory level. Special concern should be given for the monitoring process and proper technical maintenance of the existing water treatment plant.
