Abstract
Wolaita Sodo town suffering the shortage of safe water supply service due to increasing population. The aim of study was evaluating the performance of water supply system to develop strategies to improve the situation for the future. 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.

Water is a very basic necessity of life
To evaluate and monitor the rate of success, or failure, in meeting this objective, water supply utilities employ a set of Performance Indicators (PIs), quantitative data, which reflect on the performance of various components of the water supply system (2)
This research is conducted in this town to assess the performance of the existing water supply system by using user perceptions and IWA performance indicator system of water resource, personnel, physical, operational, quality of service and financial and the strategy is developed to improve the current situation of the water supply system in the town
Summary
Water is a very basic necessity of life. The planet earth has enormous quantity of water, but usable water is very limited (1). As the household survey carried out by the socio economic group of the consultant, it was reported that about 59.9% of the households get safe water whereas the remaining 40.1% do not have safe water supply access (5) This shows the shortage of the water in the town. An average annual water loss of the town is 143,047m3/year To this effect these households use unprotected sources such as un-protected spring, hand dug well and river (6). This research is conducted in this town to assess the performance of the existing water supply system by using user perceptions and IWA performance indicator system of water resource, personnel, physical, operational, quality of service and financial and the strategy is developed to improve the current situation of the water supply system in the town
