COV Kladno Svermov Wastewater Treatment Plant, Kladno, Czech Republic

COV Kladno Svermov is a municipal wastewater treatment plant located in the Kladno district of the Central Bohemian Region, Czech Republic. The facility serves a population of approximately 5,900 residents, classifying it as a small to medium agglomeration under EU classification. The plant provides secondary biological treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 6,616 cubic meters per day and an average discharge volume of 986 cubic meters per day, the plant operates well within its capacity, ensuring effective treatment of incoming wastewater. The treated effluent is discharged into local streams that ultimately drain into the Elbe River, a major waterway flowing through Central Europe to the North Sea. The plant plays a key role in protecting the water quality of the Elbe basin, supporting aquatic life and downstream ecosystems.

The plant discharges into the Elbe River basin, which flows through the Czech Republic and Germany before reaching the North Sea. The Elbe supports diverse aquatic habitats and is an important migratory corridor for fish species. The secondary treatment provided by the plant helps reduce nutrient and organic pollution, mitigating eutrophication risks in downstream waters.
