COV Libochovice Wastewater Treatment Plant - Libochovice, Czech Republic

COV Libochovice is a municipal wastewater treatment plant located in Libochovice, a town in the Ústecký kraj region of the Czech Republic. The plant serves a population of 1,387 and operates with a designed capacity of 4,600 m³/day, currently treating 551.30 m³/day of wastewater. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. For smaller agglomerations like Libochovice (under 2,000 PE), the directive requires appropriate treatment, which secondary treatment fulfills. The treated effluent is discharged into the local watershed, which ultimately drains into the Ohře River and then the Elbe River, flowing through Germany into the North Sea. This connection to the Elbe basin highlights the plant's role in protecting downstream water quality in a major European river system.

The plant discharges into the Ohře River basin, a tributary of the Elbe River, which flows through the Czech Republic and Germany before reaching the North Sea. The Elbe estuary supports diverse aquatic life and is an important migratory corridor for fish species. The secondary treatment provided by the plant helps reduce organic pollution and nutrient loads, protecting the ecological health of the downstream river system.
