COV Sabinov Wastewater Treatment Plant, Ražňany, Slovakia

COV Sabinov is a municipal wastewater treatment plant located in Ražňany, in the Prešovský kraj region of eastern Slovakia. The plant serves a population of approximately 19,242 people, classifying it as a medium-sized agglomeration under EU classification standards. As a plant in an EU member state, COV Sabinov operates under the 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 treated effluent from COV Sabinov is discharged into local watercourses that ultimately drain into the Hornád River basin, which flows southward into the Tisza River and eventually reaches the Black Sea. The plant plays a key role in protecting the water quality of these downstream ecosystems.

The plant discharges into the Hornád River basin, a tributary of the Tisza River, which flows into the Danube and finally the Black Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. The plant's treatment helps prevent nutrient pollution and protects downstream water quality.
