| 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. |
