Access to safe water and sanitation facility has lately become a luxury in the capital cityrnAddis Ababa, specifically in the slum areas. Drinking water should be available inrnsufficient quantities at all times, it is unlikely that in the short term all countries can attainrnthat level of service. Where services are unreliable or intermittent, households typicallyrnstore water to ensure that it is available when needed. They may also restrict theirrnconsumption when water sources are far away, available only for a few hours a day or atrncertain times of the year, or out of service.rnThe objective of this study was to assess the water supply and sanitation facility of GulelernSub-city selected woredas and come up with the possible recommendations that willrnimprove and ensure the sustainability of the water and sanitation facilities of the area.rnAccordingly, the study area was selected based on the vulnerability of the area for WASHrnfacilities and the researcher's prior exposure. To make this particular research morernpractical and tangible, the methodology had focused on the conceptual frameworkrnformulated based on Water Availability, Water Accessibility, Quality of Water Supplied,rnand Sanitation Facility. To achieve the objectives and explain the research scenario, arndescriptive survey research method was adopted. Besides, both qualitative and quantitativernapproaches were adopted.rnThe 120 households survey results living in Gulele sub-city slum areas indicated that 69%rnof the households have a piped water connection and 17% of main water sources are publicrntaps, and the remaining 14% get water from other water sources. The households receivernhighly interrupted and the availability of water was on average 1 day per week with anrnaverage duration of less than 6 hours per day. Regarding its quality, 65% said the water is rnviiirnunacceptable and has a color. Concerning sanitation, the majority, 92% have a dry pitrnlatrine and they donâ€™t have a fixed handwashing facility. In these toilets, on average onernlatrine serves 12 people. On top of that, the septic tank is discharged to an open drain andrnit has a leakage most of the time, which can eventually affect the health of the community.rnThe study indicated that the dwellers are highly dissatisfied with the current water andrnsanitation service delivery characterized by long time persistent problems. The concernedrngovernment bodies are expected to take immediate action to solve these problems,rnotherwise, the current situation which is affecting the health and economic status of therncommunity will intensify. In this study, it was identified that the major causes of the lackrnof adequate water supply in the area were the shortage of supply, the connectivity problem,rnpopulation growth, topography, and enhanced economic activity.rnIn this research, short-term and long-term recommendations were forwarded, whichrnincludes the development of policies on targeting the slum areas. Besides, uninterruptablerndistribution of water, efficient management of public taps, and toilets on the existingrninfrastructure as well as its rigorous maintenance should be addressed in the short term.
