COV Horsovsky Tyn Wastewater Treatment Plant, Horšovský Týn, Czech Republic

COV Horsovsky Tyn is a municipal wastewater treatment plant located in Horšovský Týn, a town in the Plzeňský kraj region of the Czech Republic. The plant serves a population of approximately 4,131, placing it in the small agglomeration category under EU classification. As a Czech facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The Czech Republic has implemented this directive through national legislation, ensuring that plants like COV Horsovsky Tyn meet appropriate treatment standards to protect water quality. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Radbuza River, a tributary of the Berounka River, and then into the Vltava River, which flows through Prague and joins the Elbe River before reaching the North Sea. This connection to a major European river system underscores the plant's role in maintaining downstream water quality.

The plant discharges into the Radbuza River basin, which flows into the Berounka River, a key tributary of the Vltava River. The Vltava joins the Elbe River, which drains into the North Sea, making this plant part of a transboundary water system. The watershed supports diverse aquatic life and is important for regional biodiversity, including fish species such as brown trout and grayling. Proper treatment helps prevent nutrient pollution that could affect downstream ecosystems.
