FEASIBILITY STAGE DESIGN ASSESSMENT FOR TRANSFORMING AN UNPRODUCTIVE DAM INTO A SANITARY LANDFILL SITE

In many cities in Turkey, a lack of provision made for waste services is often the result of inadequate financial resources, and a lack of management and technical skills within individual municipalities. Unexpected influxes of refugees, especially, means that the planned limits for waste management by government authorities are exceeded, despite these being in place to deal with rapid growth in demand for waste management services. Urban solid wastes increase in correlation with the population and also economic growth. However, determination of a solid waste storage facility area is dependent on a number of specific criteria making it increasingly difficult to specify a suitable sanitary landfill location. Urban solid waste management and assessment of storage alternatives include complex and time-consuming processes for design engineers. Suitable site selection for solid waste storage requires a huge amount of spatial data processing, including a combination of regulation and acceptance criteria. Site selection criteria are generally based on limiting factors such as land use, geology, political and governmental boundaries, water resources, transportation, and expropriation. However, these criteria can be taken into consideration based on the engineer's judgment as well as local standards. The aim of this study is to assess the alternative method of repurposing an unproductive dam reservoir area as a sanitary landfill site due to it being a timely and cost-effective solution. Within this context, engineering approaches have been utilized under feasibility stage design in terms of ground permeability and natural structural materials, which are essential in minimizing economic and technical restrictions.
