In recent centuries, issues such as efficient use of water resources, water quality and water supply have become important for many countries. Countries have focused on developing strategies that can protect water and using water in the most efficient way including treatment of wastewater. In addition, it has become important to provide sustainability of the natural treatment systems instead of complex and expensive wastewater treatment facilities that are rapidly developing. On the other hand, the researches on natural treatment of wastewater are still inadequate. Therefore, the feasibility and performance of new stragtegies about natural treatment systems should be developed and evaluated. For this purpose, a pilot facility was developed which utilizes a natural soil-column with different gradations in order to provide the treatment of domestic wastewater. In this way, not only the wastewater treatment performances of different soils but also some engineering properties of soils affected by wastewater filtration were examined. As a result of this research, it was found that soil filtration can be effective in the treatment of wastewater subjected to pre-sedimentation and can be affected by the pollutant load of the filtration environment.
