It was carried out using six performance indicators suggested by International Water Association (IWA) this was analyzed by SIGMA lite and user perception data that analyzed by SPSS. As study indicates, average consumption for about 73% of households was less than 20 liter/capita/day. Most of the households (i.e. 53%) were dependent on public tap, vendors and unprotected spring as a primary water source. About 22% of households depend on neighboring water vendors and pay high price (i.e. average of 70.6 ETB/month) for poor drinking water source. Among the six IWA indicators of water supply service; operational indicators and quality of service indicators fully showed a good performance. However, from water resource indicators (consumer satisfaction & production/person/day); from personnel indicators (employees/connection), all physical indicators and from financial indicators (water tariff) need some improvement. Generally as the results of the study shows, there was a shortage of water supply service in the town due to the problem of existing water supply system.
