GIS Based Mapping and Analysis of  Municipal Solid Waste Collection  System in Wa, Ghana

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.

The Town

Waste collection is one of the most important public services in a town. However, waste collection has not been effectively implemented in some places due to the lack of economic and management resources. The waste is placed in inappropriate sites with the consequent risks of pollution and unhealthy conditions for the inhabitants. Therefore, establishing a municipal solid waste collection plan can be complicated. The methodologies and techniques that work in countries with medium and high income levels cannot be extrapolated to others with low income level because the boundary conditions are widely different. The aim of this paper is to design a municipal solid waste collection system adapted to this type of situation where not much money can be invested and where data are limited. In these cases, municipalities need to use their existing resources effectively. This paper offers a methodology for these cases as well as a case study. The first step was to gather information about the type and amount of waste generated and the characteristics of the town. The second step was to propose the location of the bins and, finally, the waste collection routes. With all these data, the technical and human resources were set. The methodology used was validated in a real case, the town of Nikki (Benin) in Africa. The collection of three waste fractions was designed with the actual resources of the city in order to offer a realistic implementation. Similar situations can be found around the world, and this case study can be used as an example to improve the waste management practices in some places with low resources.
