COV Kokava nad Rimavicou Wastewater Treatment Plant, Banskobystrický kraj, Slovakia

COV Kokava nad Rimavicou is a municipal wastewater treatment plant located in the town of Kokava nad Rimavicou, within the Poltár district of Banskobystrický kraj, central Slovakia. The plant serves a small population of 686 residents, reflecting its role in a rural community. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 6,500 m³/day and an actual discharge volume of 140.39 m³/day, the plant operates well below its capacity, indicating ample headroom for future growth or seasonal variations. The treated effluent is discharged into local waterways that ultimately drain into the Rimava River, a tributary of the Slaná River, which flows into the Tisza River and eventually the Danube River and Black Sea. The plant plays a key role in protecting the water quality of these downstream ecosystems.

The plant discharges into the Rimava River basin, which feeds into the Slaná River, a major tributary of the Tisza River. The Tisza flows into the Danube, which empties into the Black Sea. The local watershed supports diverse aquatic life and is important for migratory fish species. Secondary treatment helps reduce nutrient loads, protecting downstream water bodies from eutrophication.
