COV Libčice nad Vltavou Wastewater Treatment Plant - Secondary Treatment, Vltava River Basin

COV Libčice nad Vltavou is a municipal wastewater treatment plant located in Libčice nad Vltavou, a town in the Středočeský kraj region of the Czech Republic. The plant serves a population of approximately 2,014 people and has a designed capacity of 4,533 m³/day, with an average discharge volume of 388.70 m³/day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU effluent standards. The treated wastewater is discharged into the Vltava River basin, which flows northward through Prague and eventually joins the Elbe River. The Elbe then continues through Germany to the North Sea. The plant plays a key role in protecting the water quality of the Vltava, a major river supporting diverse aquatic life and recreational activities in the region.

The plant discharges into the Vltava River, a major tributary of the Elbe River, which ultimately drains into the North Sea. The Vltava flows through Prague and supports a variety of fish species and riparian ecosystems. Downstream, the Elbe estuary is an ecologically sensitive area for migratory birds and aquatic habitats. Secondary treatment helps reduce nutrient loads, mitigating eutrophication risks in the river and downstream coastal waters.
