This thesis aims to propose a design of a vertical flow constructed wetland for a village up to 500 PE. The project is conducted for the town of Vlachova Lhota (Zlín district), and two alternatives are presented here. The first is based on mechanical pre-treatment and an intermittently loaded vertical flow constructed wetland. This alternative meets the state limits of wastewater discharge, which was demonstrated by a calibrated model of the effectiveness of an intermittently loaded vertical flow constructed wetland. This model was designed by Ing. Mirka Němcová using Hydrus software. The second alternative includes, in addition to the first design, tertiary sewage treatment. Tertiary treatment was proposed as an effective solution to removing all monitored pollutants in wastewater discharge. A combination of technologies of tertiary sewage treatment has not been put into practice, therefore the outcome and the effectiveness of the process can only be estimated. Tertiary sewage treatment would function as the first operational research unit, which could produce further findings in the field of sewage treatment using nature-based methods.
