COV Kozlovice Wastewater Treatment Plant, Měrkovice, Moravskoslezský kraj

COV Kozlovice is a municipal wastewater treatment plant located in Měrkovice, part of the Kozlovice municipality in the Moravskoslezský kraj region of the Czech Republic. The plant serves a population of 2,104 and has a designed capacity of 2,500 m³/day, with an average discharge volume of 756.23 m³/day. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to remove organic matter and suspended solids, ensuring compliance with EU effluent quality standards. The treated effluent is discharged into local watercourses that drain into the Odra River basin, ultimately reaching the Baltic Sea. The plant plays a key role in protecting the region's water quality and supporting the ecological health of downstream aquatic habitats.

The plant discharges into small streams that flow into the Odra River basin, which drains northward into the Baltic Sea. The local watershed supports diverse aquatic life and is part of a broader ecosystem that includes floodplain forests and wetlands. Effective wastewater treatment is essential to prevent nutrient enrichment and maintain water quality in this sensitive riverine environment.
