Work included:
· Population and solid waste projections up to year 2005
· Topographical and hydrogeological studies, including availability of soil for sanitary landfilling, area required, site capacities, proximity of potential sites to existing settlements, and other environmental factors. The absence of fresh water aquifers in the region to some degree facilitated the delineation of alternative sites
· Study of nine potential sites for sanitary landfill, and their ranking according to environmental and engineering criteria, as well s site availability and overall suitability. Two sites were selected as being the most suitable
· Preparation of cost estimates for each of the sites, taking into account excavation and land preparation, canal cross-sections and lining, volume of fill, length of fences and access roads, labour and machinery costs, etc.
Disposal costs for the most suitable sites available were found to range from US$ 6.4 to 7.1/ton, including transport.
Based on a decision by the planning and environmental authorities, the Dudaim site was ultimately selected for sanitary landfill design.
Components include: access road; water supply pipeline with booster; excavation and landfilling, using the excavated material for cover; drainage system for removal of rainwater from inside and outside the facility; truck scale; truck washing facility; and ponds for treatment of liquid wastes.
The plant has been operating since 1990. |
