COV Stara Lubovna Wastewater Treatment Plant, Stará Ľubovňa, Slovakia

COV Stara Lubovna is a municipal wastewater treatment plant located in Stará Ľubovňa, a town in the Prešovský kraj region of eastern Slovakia. The plant serves a population of approximately 11,800 people, classifying it as a medium-sized agglomeration under EU standards. As a Slovak facility, the plant 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 goals. The treated effluent from COV Stara Lubovna is discharged into the local watershed, which ultimately drains into the Poprad River, a tributary of the Dunajec River. The Dunajec flows into the Vistula River and then to the Baltic Sea. The plant plays a key role in protecting the water quality of these downstream water bodies, supporting aquatic life and maintaining the ecological balance of the region.

The plant's discharge enters the Poprad River basin, which flows through the Carpathian landscape into the Dunajec River and eventually the Vistula River, reaching the Baltic Sea. This watershed supports diverse aquatic habitats and is important for migratory fish species. The region's mountainous terrain and seasonal precipitation patterns influence runoff and dilution capacity, making effective treatment essential for maintaining downstream water quality.
