COV Bystrany Wastewater Treatment Plant, Olcnava, Slovakia

COV Bystrany is a former wastewater treatment plant located near Olcnava in the Košický kraj region of eastern Slovakia. The plant provided secondary treatment for municipal wastewater, serving the local community before its closure. As a facility in a rural area, it contributed to the region's sanitation infrastructure. As a secondary treatment plant, COV Bystrany would have met the standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this scale. The plant's closure may reflect upgrades or consolidation of wastewater services in the region. The plant's receiving waters likely drain into the Hornád River basin, which flows southward through eastern Slovakia and eventually into the Tisza River and the Danube River system. The area is part of the broader Carpathian region, known for its diverse aquatic ecosystems.

The plant's treated effluent would have discharged into local streams that feed the Hornád River, a tributary of the Tisza River, which ultimately flows into the Danube River and the Black Sea. The Hornád River supports diverse aquatic life, including fish species such as the European grayling and brown trout. The surrounding region is ecologically sensitive due to its location in the Carpathian Mountains, which host important forest and freshwater habitats.
