Abstract: In Nigeria, waste disposal have been ineffective both in the urban and rural areas. Wastes are indiscriminately dumped on open plots of land and particularly along streets rendering the roads impassable and reducing the aesthetic value of the area. Several attempts have been made to solve the problem to no avail. Selection of waste collection points is therefore necessary in other to prevent the indiscriminate dumping of waste which is hazardous to human health. This study used Geographic Information Systems (GIS) to select suitable locations for waste collection points at Ikenegbu extension layout. A database was created and GIS systems were used in the analyses. This resulted in the generation of digital maps which can be very much useful in decision making for waste management or any other earth related problem. These maps were designed (digitized and georeferenced) in AutoCAD land development 2i and analysed with the inputed database in ArcView 3.2a through the usage of its analytical capabilities like buffering, overlay by union, clipping and query operations to determine the most suitable sites for solid waste collection in the area.
