COV Velke Karlovice Wastewater Treatment Plant, Velké Karlovice, Zlínský kraj

COV Velke Karlovice is a wastewater treatment plant located in the municipality of Velké Karlovice, within the Zlínský kraj region of the Czech Republic. The plant serves a population of approximately 1,535 residents, classifying it as a small agglomeration under EU standards. It is situated in the mountainous area of the Vsetín district, part of the Moravian-Silesian Beskids. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 2,100 m³/day and an average daily flow of 384.84 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. Secondary treatment typically involves biological oxidation and settling. The treated effluent is discharged into a local watercourse that eventually drains into the Vsetínská Bečva River, a tributary of the Bečva River, which flows into the Morava River and ultimately the Danube River basin. This discharge contributes to the water quality of the Danube watershed, which supports diverse aquatic ecosystems and is a vital water resource for Central Europe.

The plant discharges into a local stream that feeds the Vsetínská Bečva River, part of the Morava River basin, which flows into the Danube River. The Danube is Europe's second-longest river, supporting a wide range of fish species and migratory birds. The surrounding area is ecologically sensitive due to its location in the Carpathian mountain region, which hosts diverse flora and fauna. Proper treatment helps protect downstream water quality in this important transboundary river system.
