COV Raslavice Wastewater Treatment Plant - Raslavice, Prešovský kraj, Slovakia

COV Raslavice is a municipal wastewater treatment facility located in the village of Raslavice, within the Bardejov District of Prešovský kraj in eastern Slovakia. The plant serves a population of 1,453 residents, placing it in the small-agglomeration category under EU classification. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 2,250 m³ per day, with an actual discharge volume of 297.36 m³ per day, indicating significant spare capacity for future growth or seasonal variations. The treated effluent is discharged into local waterways that ultimately drain into the Topľa River, a tributary of the Ondava River, which flows into the Bodrog River and then the Tisza River, eventually reaching the Black Sea. The plant plays a key role in protecting the water quality of these downstream rivers and the broader Tisza basin ecosystem.

The plant discharges into the Topľa River basin, part of the larger Tisza River catchment that flows into the Black Sea. This region supports diverse aquatic life and is important for migratory fish species. The advanced treatment level helps reduce nutrient loads, protecting downstream water bodies from eutrophication and maintaining ecological balance in the sensitive Carpathian foothill streams.
