Abstract

The treatment and disposal of wastewater still is a big problem of Antalya. The wastewater produced in the residential areas is biologically treated, the produced sludge, however, remains untreated. At the moment more than 60 t/day of dewatered sludge are buried at a landfill area located directly above the main groundwater resources of the city. As the area does not have any drainage and liner systems, it is believed that this kind of disposal constitutes a threat to the groundwater resources. Therefore, Antalya Metropolitan Municipality decided to add anaerobic sludge digestion units to the wastewater treatment plant. The sludge digestion tanks are considered to be built within the wastewater treatment plant area which is less than 1 km away from the beaches along the Mediterranean Sea. The purpose of this study is to examine the foundation soil in terms of its bearing capacity, consolidation settlement, and earthquake risks and to find out whether this construction site is suitable for building the sludge digestion tanks or not.
