| dc.description.abstract | Generation of solid waste is immensely increasing as the rate of population influx into urban area is increasing. This condition demands scientific approach of solid waste disposal site selection for proper urban solid waste management. Therefore, the aim of this study was to identify suitable solid waste disposal site that consider environmental friendly, economically cost effective and socially acceptable in Sululta Town, Oromia Special Zone Surrounding Finfinne, by using the geographical information system and the analytic hierarchy process. The criteria for site selection used are slope, surface material, geological feature, hydro geological feature, distance from the water body, prevailing wind direction, distance from built-up areas, and distance from the main roads. Multi-criteria evaluation methods are used for solid waste disposal site selection. The final weighted model was grouped as unsuitable, least suitable, moderately suitable, and suitable site. The results of the analysis show that 7% of the study area was suitable for solid waste disposal, 10% moderately suitable, 21% least suitable and 62% of the total area is unsuitable. Evaluating those potential suitable solid waste disposal sites was made through determinant criteria such as distance from river, size of the site, wind direction, distance from built up area and distance from main roads so as to choose the best suitable site. However, evaluation of candidate sites in relation to their size shows that all suitable solid waste disposal site 1(24 ha), 2(30 ha), 3(69 ha) and 4(300 ha) with area coverage of more than 24 ha, are equally suitable sites as it could serve for longer years. But, from the wind direction perspective, the dominant wind blows from southern direction followed by south eastern which posed further pollution to the down central town residents if the site determined along the area. Hence, suitable solid waste disposal site 1 was more preferable site than other sites in terms of many set criteria and proposed best suitable site for solid waste disposal in the town.
