One of the problems caused by population growth is the problem of solid waste managementrnsystems. This problem is particularly acute in developing countries such as Ethiopia. Therntraditional solid waste management system which is dumping solid waste on open platformsrnwithout applying any specific technology and without suitability study is polluting Addis Ababarnwhich is the capital city of Ethiopia and, it overshadows the beauty of the city. Also, these smallscalernsolid waste transfer sites are creating a foul odor and affect the peopleâ€™s health that livesrnand use the area. Based on this, the objective of this study focuses on, Assessing the impact ofrnsolid waste transfer sites and locating sustainable sites by using GIS techniques in one selectivernsub-city in Addis Ababa which is Addis Ketema sub-city. The method that was applied for thernstudy is more descriptive that to show clearly or to make it visible the existing situation of solidrnwaste transfer sites. Based on the results, the researcher study different criteria (guidingrnprinciples) to proposed potential suitable sites for solid waste transfer stations. A transferrnstation is a building or processing site specially designed for the temporary deposition of solidrnwaste. According to this, about five social and physical criteria were used to select the potentialrnsite and All maps were Geo-referenced and reclassified according to their suitability and basedrnon the standards of solid waste transfer station site selection. As the result showed, from the totalrnstudy area 3.6% was found as the most suitable location for solid waste transfer station, 8.7%rnsuitable, 9.3% were moderately suitable and 78.4% was unsuitable for locating solid wasterntransfer station. This sustainable site was satisfied both the environmental and social norms andrnprinciples that used to locate solid waste transfer station potential locations in the study area.rnBased on this, all concerned governmental bodies should give proper attention to differentrnguiding principles and norms for the best result on solid waste management process on solidrnwaste transfer station locations in the city of Addis Ababa, on sub-city level.
