Abstract The study focused on the assessment of water supply service provision limitations and its effects in Masha town of south western Ethiopia. In the town, piped water service unavailability and quality was common issues to water users. On the other hand, topography of Masha town is undulating and equity in water service was under question. The study mainly aimed to assess the existing situation of the service, water sources for domestic activities, perception for the lowquality piped water and evaluating the service based on key physiochemical parameters and pressure. Existing water service were assessed based on site visits checklists, questionnaires and interviews of service providers. Out of total 4586 households in the town sample size of 100 were selected using standard procedures. Water quality sample was tested at different locations in water supply system from source to point of supply using photometer, pocket colorimeter and PH meter apparatuses. Pressure of water service in the town were modeled using Water GEMs which was calibrated by actual measured pressure data. The study indicates that existing estimated demand of water for the town was 1477.31 m /day and designed capacity of existing water supply system was 803.52 m 3 /day (54.39 % of current demand). Existing water production amount was 33% of total production capacity and only 15.56% of total capacity were pumped to central reservoir. The cause for limited service capacity were found to be inefficient institutiona l capacity of service providers that leads to inappropriate operation and maintenance. The socioeconomic analysis result depicted that all of households were dissatisfied with piped water service and its primary common cause were service unavailability (66 %) and degraded water quality (33%). Water quality test result of the town showed that average concentration of Fe, Mn, PH and Free Cl2 were 1.430 mg/l, 0.005mg/l, 7.48 and zero respectively. Iron (Fe) was found far high above recommended value of 0.3 mg/l that makes the piped water to be in a very high-risk category. As the model result showed that pipe water pressure was very low in some areas of the town like center of the town where high vertical development was undergoing. Therefore, water supply service of the town has limitations on water quality, availability and equity in the town due to inefficiency of treatment plant and institutional capacity of service providers. The service states has high risk for piped water users and needs water safety planning, household water level treatment practice, upgrading treatment plants and zonal supply for low pressure areas.
