COV Jesenske Wastewater Treatment Plant, Jesenské, Slovakia

COV Jesenske is a wastewater treatment plant located in Jesenské, a village in the Rimavská Sobota District of Banskobystrický kraj, central Slovakia. The plant provided secondary treatment for the local population before its closure. As a secondary treatment facility, COV Jesenske would have met the minimum treatment standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of its size. The directive mandates secondary treatment for all discharges from agglomerations above 2,000 population equivalent, with more stringent requirements for sensitive areas. The plant's treated effluent would have been discharged into a local watercourse, likely a tributary of the Rimava River, which flows into the Slaná River and eventually the Tisza River basin. The Tisza drains into the Danube and ultimately the Black Sea. The surrounding region is characterized by agricultural land and small settlements, and the local watershed supports diverse aquatic life.

The plant's discharge would have entered a local stream within the Rimava River basin, which flows into the Slaná River, a tributary of the Tisza. The Tisza River system is ecologically significant, supporting diverse fish populations and migratory birds. The area is part of the broader Danube Basin, which drains into the Black Sea. Proper wastewater treatment is crucial to prevent nutrient pollution and protect downstream aquatic ecosystems.
