COV Rokycany Wastewater Treatment Plant - Rokycany, Czech Republic

COV Rokycany is a municipal wastewater treatment plant located in Rokycany, a town in the Plzeňský kraj region of the Czech Republic. The plant serves a population of approximately 9,347 residents, placing it in the small-to-medium agglomeration category under EU classification. As a plant serving fewer than 10,000 people, COV Rokycany is required under the EU Urban Waste Water Treatment Directive (91/271/EEC) to provide at least secondary treatment. The Czech Republic implements this directive through national legislation, ensuring that discharges meet biological oxygen demand and suspended solids standards. The regulatory framework ensures appropriate treatment for this population tier. The treated effluent from COV Rokycany is discharged into the local watershed, which ultimately drains into the Berounka River, a tributary of the Vltava River. The Vltava flows north through Prague and joins the Elbe River, which empties into the North Sea. This downstream connection highlights the plant's role in protecting water quality across regional and international boundaries.

COV Rokycany discharges into the Berounka River basin, which flows into the Vltava River, a major tributary of the Elbe River. The Elbe drains into the North Sea, making this plant part of a transboundary watershed. The Berounka River supports diverse aquatic life and is an important ecological corridor in the Plzeň region. Downstream, the Vltava and Elbe rivers provide habitat for fish species such as salmon and sturgeon, and their water quality is critical for both ecosystem health and human use.
