COV Klanovice Wastewater Treatment Plant, Prague, Czech Republic

COV Klanovice is a wastewater treatment plant located in the Klanovice district of Hlavní město Praha, Czech Republic. The plant serves a population of 3,115, placing it in the small agglomeration category under EU regulations. It is situated in the eastern part of Prague, an area characterized by urban and suburban development. The plant employs advanced treatment processes, which go beyond the secondary treatment 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 water bodies. The plant has a designed capacity of 6,055 m³/day and currently discharges a volume of 539.16 m³/day, indicating significant spare capacity. The treated effluent is discharged into local watercourses that eventually drain into the Vltava River, a major tributary of the Elbe River, which flows into the North Sea. The plant plays a key role in protecting the water quality of the Vltava basin and downstream ecosystems, including the Elbe estuary.

The plant discharges into the Vltava River catchment, which flows through Prague and joins the Elbe River before reaching the North Sea. The Vltava basin supports diverse aquatic life and is an important ecological corridor in Central Europe. The advanced treatment at COV Klanovice helps reduce nutrient loading to the river, mitigating eutrophication risks in downstream reservoirs and the Elbe estuary.
