COV Vlasim Wastewater Treatment Plant, Vlašim, Czech Republic

COV Vlasim is a municipal wastewater treatment plant located in Vlašim, a town in the Středočeský kraj region of the Czech Republic. The plant serves a population of approximately 11,805 people, making it a medium-sized agglomeration under Czech and EU classifications. As a Czech facility, COV Vlasim operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes are designed to meet these regulatory standards, ensuring compliance with national and EU water quality requirements. The treated effluent from COV Vlasim is discharged into the local water system, which ultimately drains into the Blanice River, a tributary of the Sázava River, and then into the Vltava River, which flows through Prague before joining the Elbe River and reaching the North Sea. The plant plays a key role in protecting the water quality of these downstream rivers and the broader Elbe basin ecosystem.

COV Vlasim discharges treated wastewater into the Blanice River, which flows into the Sázava River, a tributary of the Vltava River. The Vltava joins the Elbe River, which drains into the North Sea. The plant helps protect the aquatic ecosystems of these rivers, which support diverse fish populations and serve as important migratory corridors for species such as salmon and eel.
