COV Dolni Chabry Wastewater Treatment Plant, Hlavní město Praha, Czech Republic

COV Dolni Chabry is a wastewater treatment plant located in the Dolni Chabry district of Hlavní město Praha, Czech Republic. It serves a population of 2,265 and operates with a designed capacity of 4,950 m³/day, currently discharging 722.91 m³/day of treated wastewater. 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. This level of treatment is typical for plants discharging into sensitive areas or where higher effluent quality is needed to protect receiving waters. The treated effluent likely enters the Vltava River basin, which flows through Prague and eventually joins the Elbe River, draining into the North Sea. The plant's advanced treatment helps reduce nutrient loads and protect aquatic ecosystems in this important Central European waterway.

The plant discharges into the Vltava River basin, a major tributary of the Elbe River, which flows through Germany and into the North Sea. The Vltava supports diverse aquatic life and is an important migratory corridor for fish. Advanced treatment at this plant helps minimize nutrient pollution, which is critical for preventing eutrophication in downstream waters, including the North Sea.
