COV Tremosnice Wastewater Treatment Plant, Třemošnice, Pardubický kraj

COV Tremosnice is a municipal wastewater treatment plant located in Třemošnice, a town in the Pardubický kraj region of the Czech Republic. The plant serves a population of approximately 3,415 residents, placing it in the small agglomeration category under EU classification. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 5,083 m³/day and a reported discharge volume of 861.83 m³/day, indicating operational headroom. Treated effluent from COV Tremosnice is discharged into the local watershed, which ultimately drains into the Doubrava River and then the Elbe River basin. The Elbe flows through Germany to the North Sea, making the plant part of a transboundary river system. Proper treatment helps protect downstream aquatic ecosystems and water quality in the Elbe catchment.

COV Tremosnice discharges into the Doubrava River, a tributary of the Elbe River, which flows through Germany to the North Sea. The Elbe basin supports diverse aquatic life and is an important migratory corridor for fish species. The plant's secondary treatment helps reduce nutrient and organic pollution, contributing to the ecological health of the downstream river system and the North Sea coastal environment.
