5.2. Recommendations

The major problem encountered during this study was lack of some of the required data that may improve the quality of the final result. Ground water levels of the recommended suitable sites were not measured because of costs involved, lack of technical equipment required for that functionality, and time. Soil types map was missing while (Sadek, El Fadel, & El Hougeiri, 2001) emphasize that in the selection of a site for MSW land-filling, special care has to be given to the underlying foundation soil and bedrock characteristics: geologic structure, soil type, existing fractures, and so on. The starting point is a geologic map of the study area showing the geologic characteristics, the chronology of a bedrock formation and lithology.

The recommendations for future urban planning and further research are the following:

1. Establish a solid waste management structure that improves MSW collection; transportation, treatment and disposal.

2. Conduct further studies, including a comprehensive Environmental Impact Assessment, to establish the suitability of 04 potential landfill sites in Mururu Sector and 01 potential site located in Gihundwe Sector.

3. Launch public education and awareness campaign on safe waste handling and disposal methods given that 50% of the population relies on compost pits while 40% of ordinary households on the farms.
