COV Velim Wastewater Treatment Plant, Velim, Czech Republic

COV Velim is a municipal wastewater treatment plant located in Velim, a town in the Kolín District of the Central Bohemian Region, Czech Republic. The plant serves a population of 1,165 and operates with secondary treatment, which is appropriate for small agglomerations under Czech and EU regulations. As a secondary treatment facility, COV Velim meets the minimum requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations under 10,000 population equivalent. The plant has a designed capacity of 2,000 m³/day and currently discharges 247.46 m³/day of treated wastewater, indicating ample reserve capacity for future growth. The treated effluent from COV Velim is discharged into local watercourses that ultimately drain into the Elbe River basin. The Elbe flows through Germany to the North Sea, making this plant part of a transboundary river system. The receiving waters support diverse aquatic life and are important for regional water quality management.

COV Velim discharges into the Elbe River basin, which flows through the Czech Republic and Germany before reaching the North Sea. The local watershed includes agricultural and urban areas, and the plant's secondary treatment helps protect downstream ecosystems from nutrient pollution and organic loads. The Elbe basin supports diverse fish populations and is a critical migratory corridor for aquatic species.
