Household Generated Solid Waste Collection System Management Using Arcgis: a Case of Jimma Town, Southwestern Ethiopia

Abstract

Proper management of solid waste collection is one of the challenges in the urban areas of developing countries like Jimma town. Therefore, this study aims to assess the municipal solid waste collection system in Jimma town using geographical information system, GIS, techniques. Data used were digital elivation model, DEM, river shapefile, and coordinates of the locations of municipal solid waste, MSW, collection containers and open disposal site. Distances of the locations of existing MSW collection bins from the surface water, the contour lines and flow directions of areas around the existing Qofe Open Dump Site were evaluated. The findings of the study indicate that there was one waste container that was allocated in a 20 m buffer distance from the river. The solid waste collection bins in the town were not evenly allocated. The allocated waste collection containers covered only 12.32% of the total area of the town. There were about 34(51.52%) shortage of MSW collection bins in the town. The municipality should transfer collection bins placed in the river buffer zone of 20 m to other suitable locations. Unserved areas of the town should have waste collection containers after further detail investigation. Water sources near the open disposal site need to be regularly monitored for quality degradation.
