COV Horni Benesov Wastewater Treatment Plant, Horní Benešov, Czech Republic

COV Horni Benesov is a municipal wastewater treatment plant located in the town of Horní Benešov, in the Moravskoslezský kraj region of the Czech Republic. The plant serves a population of approximately 1,757 residents, classifying it as a small agglomeration under EU standards. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The plant has a design capacity of 3,495 m³/day and currently treats an average daily flow of 365.30 m³/day, indicating significant spare capacity. The treated effluent is discharged into a local watercourse, which eventually drains into the Odra River basin and ultimately reaches the Baltic Sea. The plant plays a key role in protecting the local aquatic environment from nutrient and organic pollution, supporting water quality in the region.

The plant discharges into a local stream that is part of the Odra River basin, which flows through the Czech Republic, Poland, and into the Baltic Sea. The watershed supports diverse aquatic life and is an important ecological corridor. Secondary treatment helps reduce organic load and nutrients, protecting downstream habitats from eutrophication.
