The aesthetic beauty of the environment has been destroyed through anaerobic digestion of waste on inappropriate open dumps, causing offensive odours, flooding through blockages of drains and health risk to man. This calls for a need to map out suitable collection points for temporary dumping of solid waste awaiting final disposal at approved areas for effective and efficient management of solid waste to promote hygienic environment. Therefore, GIS offers solution in this regard as a decision support system for most suitable site selection.Consequently, different layers (roads, stream and land use) were created to serve the purpose of manipulation and analyses to procure most suitable site for collection point of solid waste generated in New Owerri, Imo State using Arc view 3.2a software.
