COV Velke Hamry Wastewater Treatment Plant, Bohdalovice, Liberecký kraj

COV Velke Hamry is a municipal wastewater treatment plant located in Bohdalovice, part of the Velké Hamry area in the Liberecký kraj region of the Czech Republic. The plant serves a population of 1,289 and operates under the Czech Republic's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the standard required for agglomerations of this size under EU regulations. With a designed capacity of 2,300 m³/day and a current discharge volume of 349.48 m³/day, the facility has ample capacity for future growth. The treatment process ensures that effluent meets regulatory standards before discharge. The treated wastewater is discharged into a local watercourse that flows into the Jizera River basin, eventually reaching the North Sea via the Elbe River. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems from pollution.

The plant discharges into a small stream that feeds into the Jizera River, a tributary of the Elbe River. The Elbe flows through Germany and into the North Sea, making this plant part of a transboundary watershed. The Liberecký kraj region is known for its mountainous terrain and sensitive aquatic habitats, including streams that support brown trout and other cold-water species. Secondary treatment helps reduce organic load and protect these ecosystems.
