Abstract: The study was conducted at Sululta town. The aim of the study was to determine the selected bacteriological and physicochemical quality of the drinking water of the town. Mean temperature values for the source, reservoir and pipe water were 16.75oC, 17.57oC and 18.45oC respectively. Therefore, these temperature values are beyond the recommended limit of WHO for drinking water. On the other hand, the mean values of pH for source, reservoir and pipe household water were 7.975, 7.785 and 7.085 respectively. In addition, the mean turbidity values for the source, reservoir and pipe water were 2.853FAU, 2.153FAU and 1.868FAU respectively. Hence, the pH and the turbidity values of source, reservoir and pipe water were within the recommended limit of WHO for drinking water. Meanwhile, the mean free chlorine residual values for the source, reservoir and pipe water were 0, 0.67 mg/Land 0.41 mg/L. Hence, the mean FCR values for the reservoir and the pipe water meet the recommended limit of WHO for drinking water. In this investigation all samples collected from the source, reservoir and pipe water at the household level were negative for thermotolerant coliforms and Fecal streptocci. In disagreement with this investigation previous studies showed that the underlying fractured rocks and the widespread uncontrolled waste disposals were contaminating the groundwater in Addis Ababa. In this investigation, the analysis of the water samples which were collected for both un-chlorinated and chlorinated water samples for the source, reservoir, and pipe water were safe for both selected physicochemical and bacteriological parameters except temperature. Although the drinking water is safe, it needs better sanitation activities through improvement of watershed management practices for enhancing the better quality of the drinking water. Also the town should have treatment plant.
