COV Trebon Wastewater Treatment Plant, Třeboň, Czech Republic

COV Trebon is a municipal wastewater treatment plant located in Třeboň, a town in the Jihočeský kraj (South Bohemia) region of the Czech Republic. The plant serves a population of around 17,782, placing it in the medium agglomeration category under EU classification. As a plant operating within the European Union, COV Trebon is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for discharges to freshwater and estuaries for agglomerations of this size, with more stringent tertiary treatment if the receiving waters are designated as sensitive areas. Compliance with the directive ensures a minimum level of treatment. The treated effluent from COV Trebon is discharged into the local watershed, which ultimately drains into the Lužnice River, a tributary of the Vltava River. The Vltava flows northward through Prague and joins the Elbe, which empties into the North Sea. The plant plays a key role in protecting the water quality of these downstream water bodies and the ecosystems they support.

COV Trebon discharges treated wastewater into the local watershed, which feeds into the Lužnice River. The Lužnice flows into the Vltava River, a major watercourse in the Czech Republic that passes through Prague before joining the Elbe River. The Elbe ultimately reaches the North Sea. This river system supports diverse aquatic life and is important for regional biodiversity. The plant's operations help maintain water quality in this ecologically significant network.
