COV Jablunka Wastewater Treatment Plant, Jablůnka, Czech Republic

COV Jablunka is a municipal wastewater treatment plant located in Jablůnka, a village in the Vsetín District of the Zlínský kraj region in the eastern Czech Republic. The plant serves a population of approximately 2,000 people, reflecting its role as a small-scale facility for the local community. It operates under the Czech national regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant provides secondary treatment, which involves biological processes to reduce organic matter and suspended solids. Its design capacity is 2,200 m³/day, and the reported discharge volume is 210.20 m³/day, indicating that the plant operates well below its capacity. Secondary treatment is standard for plants serving populations under 10,000 in the EU. The treated effluent is discharged into local watercourses that drain into the Vsetínská Bečva River, a tributary of the Bečva River, which flows into the Morava River and ultimately the Danube River basin. The plant plays a key role in protecting the water quality of these rivers and the downstream environment, supporting aquatic life and preventing eutrophication in the Danube catchment.

The plant discharges into local streams that feed the Vsetínská Bečva River, part of the Morava River basin, which flows into the Danube River and eventually the Black Sea. This watershed supports diverse aquatic habitats and is important for migratory fish species. The secondary treatment provided by the plant helps reduce nutrient loads, protecting downstream water quality and ecological balance.
