COV Bobr Wastewater Treatment Plant, Žacléř, Královéhradecký kraj

COV Bobr is a municipal wastewater treatment plant located in the village of Bobr, near the town of Žacléř in the Královéhradecký kraj (Hradec Králové Region) of the Czech Republic. The plant serves a population of approximately 2,375 people and has a designed capacity of 3,536 cubic meters per day, with a reported discharge volume of 916.5 cubic meters per day. The plant employs advanced treatment processes, which go beyond the secondary treatment standards required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The treated effluent is discharged into local watercourses that eventually drain into the Elbe River basin, which flows through Germany and into the North Sea. The plant's advanced treatment helps safeguard water quality in this transboundary river system, supporting aquatic ecosystems and downstream water uses.

The plant discharges into small streams near Bobr that are part of the upper Elbe River basin. The Elbe flows north through the Czech Republic and Germany, eventually reaching the North Sea. This region features mountainous terrain and sensitive headwater streams that support diverse aquatic life. Advanced treatment at COV Bobr helps control nutrient loading, protecting downstream water quality in the Elbe and its tributaries.
