The study was conducted at Sululta town. The aim of the study was to determine thernselected bacteriological and physicochemical quality of the drinking water of the town.rnMean temperature values for the source, reservoir and pipe water were 16.75oC, 17.57oCrnand 18.45oC respectively. Therefore, these temperature values are beyond thernrecommended limit of WHO for drinking water. On the other hand, the mean values ofrnpH for source, reservoir and pipe household water were 7.975, 7.785 and 7.085rnrespectively. In addition, the mean turbidity values for the source, reservoir and pipernwater were 2.853FAU, 2.153FAU and 1.868FAU respectively. Hence, the pH and thernturbidity values of source, reservoir and pipe water were within the recommended limit ofrnWHO for drinking water. Meanwhile, the mean free chlorine residual values for thernsource, reservoir and pipe water were 0, 0.67 mg/Land 0.41 mg/L. Hence, the mean FCRrnvalues for the reservoir and the pipe water meet the recommended limit of WHO forrndrinking water. In this investigation all samples collected from the source, reservoir andrnpipe water at the household level were negative for thermotolerant coliforms and Fecalrnstreptocci. In disagreement with this investigation previous studies showed that thernunderlying fractured rocks and the widespread uncontrolled waste disposals wererncontaminating the groundwater in Addis Ababa. In this investigation, the analysis of thernwater samples which were collected for both un-chlorinated and chlorinated waterrnsamples for the source, reservoir, and pipe water were safe for both selectedrnphysicochemical and bacteriological parameters except temperature. Although therndrinking water is safe, it needs better sanitation activities through improvement ofrnwatershed management practices for enhancing the better quality of the drinking water.rnAlso the town should have treatment plant
