Urban population growth together with the development of new industries and commercial centresrngenerate huge amount of solid waste daily. Like in many developing world cities a rapid populationrngrowth and high rural-urban migration posses many environmental challenges for the Addis Ababarncity. One of these is dry waste management and disposal system. In adequate dry waste managementrnhas resulted in the accumulation of solid waste on open lands, in rivers, in drains and in the living arearnof many people, causing a nuisance and foul-smelling pools, environmental pollution through leachesrnfrom piles (water and soil pollution) and burning of waste (air pollution), clogging of drains, and thernpossible spread of diseases. This situation is believed to result in poor environmental conditions and anrnever-present risk of epidemics, which in turn present a formidable threat to health and productivity.rnThe present method of disposal is crude open dumping; hauling the wastes by truck, spreading andrnleveling by bulldozer and compacting by compactor bulldozer at the only one dumpsite â€˜kosheâ€™. Therndumpsite is getting full; it is partly surrounded by residents and institutions and has no gas control. Therngas generated from landfill causes spontaneous fire and air pollution. It contributes enormous amountrnof methane (green house gas) to the atmosphere. The site has low area capacity (25 ha), poorrnprotection of ground water and surface water pollution. Now, for the time being, the environmentalrnimpact of this disposal sites on human beings, soil, air and water quality makes this issue a subject ofrnmany researchers in addressing the safe way disposal system. Proper disposal site selection of thernwaste is a challenging issue that must be addressed adequately. Land filling is one of the commonrnmethods used for waste disposal. GIS (Geospatial Information System) is a computerized tool forrnsolving environmental problems. It can then be used to optimize the selection process of landfill site.rnThrough various functionalities, GIS is able to provide a better understanding of the effects of the sitesrnon the environment.rnThe objectives of this project are to identify and evaluate the major earth related factors on landfill siternselection, and to describe the methods for proper landfill location estimation. As a case study to thernwhole part of Addis Ababa city has been selected to evaluate the candidate locations. The data usedrnincluded geologic condition (hydraulic conductivity), soil type distribution, underground water (depth),rnsurface hydrology (rivers), topographic maps and geomorphology (slope), land use property andrndistance from the main road. The data are combined together using DRASTIC procedure on arncommercial GIS software package to locate and visualize the selected site. The paper elaborates all the methodologies used, and the scientifically evaluated results. Finally, this project paper produced arnmore recommended suitable landfill sites map for Addis Ababa city. Also the project paper forwardedrna scientifically analyzed recommendation for a previously proposed landfill and existing open dumprnsite in the city
