Generation of solid waste is immensely increasing as the rate of population influx into urbanrnarea is increasing. This condition demands scientific approach of solid waste disposal siternselection for proper urban solid waste management. Therefore, the aim of this study was tornidentify suitable solid waste disposal site that consider environmental friendly, economically costrneffective and socially acceptable in Sululta Town, Oromia Special Zone Surrounding Finfinne,rnby using the geographical information system and the analytic hierarchy process. The criteriarnfor site selection used are slope, surface material, geological feature, hydro geological feature,rndistance from the water body, prevailing wind direction, distance from built-up areas, andrndistance from the main roads. Multi-criteria evaluation methods are used for solid wasterndisposal site selection. The final weighted model was grouped as unsuitable, least suitable,rnmoderately suitable, and suitable site. The results of the analysis show that 7% of the study arearnwas suitable for solid waste disposal, 10% moderately suitable, 21% least suitable and 62% ofrnthe total area is unsuitable. Evaluating those potential suitable solid waste disposal sites wasrnmade through determinant criteria such as distance from river, size of the site, wind direction,rndistance from built up area and distance from main roads so as to choose the best suitable site.rnHowever, evaluation of candidate sites in relation to their size shows that all suitable solid wasterndisposal site 1(24 ha), 2(30 ha), 3(69 ha) and 4(300 ha) with area coverage of more than 24 ha,rnare equally suitable sites as it could serve for longer years. But, from the wind directionrnperspective, the dominant wind blows from southern direction followed by south eastern whichrnposed further pollution to the down central town residents if the site determined along the area.rnHence, 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.rnKey words: Suitability, Solid waste disposal site, Analytical Hierarchical Process
