5.1. General Conclusion
Locating suitable sites for any purpose (for example
industrial, landfills, and road construction or Infrastructure development
among others) is always a major challenge faced by both the government and the
private sector due to NIMBY attitudes among the communities. Landfill site
selection results are usually faced with NIMBY syndrome in every country,
because people are concerned about their property. So in site selection, the
problem is not to find sites which cause no opposition, but the goal is to find
sites which should lead to minimum conflicts as a result of waste disposal.
The main objective of this research was to identify/ show
different suitable landfill sites for municipal solid waste in Rusizi town.
Three specific objectives have been formulated in order to achieve the main
objective. The specific objectives are: to assess the current situation of
waste generation and management in Rusizi town, to determine different criteria
for selecting a landfill site in Rusizi town, and to determine suitable site
(s) for landfill for waste dumping.
To respond to these specific objectives, multi source data and
methods were used. These included the review of government rules and
regulations regarding landfill sites selection, secondary data and primary data
collected from the field. Several input data were also integrated in this
analysis. These included Airport, Digital Elevation Model, rivers, slope, Kivu
Lake, wetland, roads, schools, hospitals, markets and forests.
Objective 1: To assess the current
situation of waste generation and management in Rusizi town
To respond this specific objective, the field study was
conducted in Rusizi District and it was found out that about 26 tons of
municipal solid waste are generated per day and a small part of it is deposited
in open dumping landfill site located in Ruganda Cell, Kamembe Sector, in
Rusizi Town given that 50% of the population relies on compost pits while 40%
of ordinary households on the farms.

Objective 2: To assess the suitability of the
current landfill sites.
33
To achieve this specific objective, the necessary criteria
including regulations and constraints were gathered through literature review.
Regulations and constraints gathered from literature review were complemented
by field study that found out that Ruganda open dumping site was not suitable
for landfill site given that it did not fulfill the environmental, political,
economic, hydrologic, topographical and geologic criteria. Furthermore, it is
located in a forest.
Objective 3: To determine suitable site(s)
for landfill for waste dumping
To achieve this objective, GIS analysis was conducted with
respect to slope, roads network, rivers, Kivu Lake, wetlands, forest, schools,
healthy facilities, markets and airport, 131 suitable landfill sites were
produced. With reference to REMA regulations regarding to suitable landfill
size, 05 best landfill sites with more than 02 ha were identified in Rusizi
town where 04 suitable landfill sites were identified in Mururu Sector and 01
suitable landfill site was identified in Gihundwe Sector.
