Greater Accra is the regional capital of Ghana with a population of 4.3 million growing at a rate of 3.5% as reported in the 2010 population and housing census. This population is estimated to produce 931 million tons of solid waste annually. Disposal of this waste has become a burden on the region since the previous practices of open dumping and controlled and uncontrolled dumping is being resisted fiercely as a population gradually becoming aware of the dangers such practices cause to both their well-being and the environment. There is hence the need to construct an engineered sanitary landfill(s) for the sustainable disposal of solid waste within region. Siting of the landfill is the most important part of the construction since several factors has to be met to be able to find the most suitable location for the landfill. This work focused on finding the best site(s) for this purpose using the techniques of remote sensing and GIS coupled with analytical hierarchy process. The method used revealed that there are several location within the Region, especially in the north-eastern part, which can house the landfill. After careful considerations two sites, which is shown in the final land parcel map, has been proposed to be the best and most suitable location for the construction and operation of an engineered sanitary landfill.
