The aim of this study was to examine the physicochemical and microbiological status of water quality from households tap, water source and reservoir in Enchini town. To achieve this objective water samples were collected from seven households tap, two sources (one spring and one borehole), and a reservoir. All samples were analyzed for Physico chemical and bacteriological water quality parameters by using standard procedures. The results show that pH, turbidity, total dissolved solid, electrical conductivity, residual chlorine, chloride of the water were ranges from 6.94-7.35,0.08-0.97 NTU,149 ppm to 343 ppm,297 μS/cm to 345 μS/cm, nill and 1.75 mg/l to 4.69 mg/l respectively. Phosphate, magnesium, calcium, nitrate, sulfate and fluoride of the water sample were also ranges between 0.18 mg/l to 0.635 mg/l, 24 mg/l to 84 mg/l, l10 mg/l to 319 mg/l ,1.4 mg/l to 3 mg/l, nill and nill-0.37 mg/l respectively. Results show that the concentration of calcium ranges from 110 mg/l to 319 mg/l in Enchini town, calcium quantity in spring (319 mg/l) was exceeding the limit set by WHO and may be harmful for local residents. All samples were positive for total coliform with counts ranging from 2-17 CFU/100 ml whereas fecal coliform were detected nill for all samples. In general the majority of the examined parameters were within the permissible limit set by WHO and Ethiopian drinking standards except calcium and total coliform.
