This thesis deals with current issues in the discharge of waste water from the urbanized area. The main aim is to evaluate the impact of rainwater on the existing unified sewerage system and the wastewater treatment plant in Brno. The theoretical part includes a brief assessment of the current state of the sewerage system of the city of Brno and the basic concepts as well as their use in everyday practice. The practical part focuses on monitoring the quantity and quality of rainwater in the sewage system at the wastewater treatment plant in Brno. These indicators have a direct impact on the safe operation of the sewerage system and wastewater treatment plants within the urban drainage. From this perspective, the work is focused on the evaluation of substance rainwater pollution discharged from busy traffic roads, both in the case of using of a single sewerage system for wastewater treatment and using a separate sewerage system that water to the recipient. To evaluate the function of the municipal sewerage system during extreme precipitation when the sewerage system is overloaded and wastewater overflows over the strain into the recipient. The contribution of the construction of one of the newly implemented retention basins was assessed. At the end of the sewerage system, ie.at the wastewater treatment plant, there were monitored changes in material composition, as well as the quantity and temperature of the influent wastewater during precipitation events, which affect the individual cleaning processes. In the conclusion, there is made an overall evaluation of the impact of precipitation water on drainage system of the city of Brno and its wastewater treatment plant. At the same time, there are evaluated newly designed concepts of drainage with respect to the already implemented measures for minimizing the impact of operational activities of sewerage system on the environment, especially the measures that aim to reduce the bag load of recipient.
