The project area of Ajdovška planota and its villages are in an area where, due to scattered and small settlements, wastewater constitutes a major economic problem. As this is a rural area, I wanted treatment to be carried out as sustainable and not intervene too much with the environment. Constructed wetlands mimics self-cleaning processes in natural wetland ecosystems, and with the help of substrate, plants and microorganisms sufficiently purify waste water. CW is inexpensive solution for wastewater treatment and system is simple to maintain. Especially in rural areas, like Ajdovška planota, where water is in shortage, the option of water reuse for irrigation. It helps maintain a natural appearance of a given landscape.
This thesis presents the natural systems of wastewater treatment, and more detailed CWs, which would perform well in small villages of Ajdovška planota. It falls within municipality of Žužemberk, which has the lowest population density in the entire country. The project area has 9 settlements, but not exceeding more than 500 people.
