COV Poltar Wastewater Treatment Plant, Poltár, Slovakia

COV Poltar is a municipal wastewater treatment plant located in Poltár, a town in the Banskobystrický kraj region of central Slovakia. The plant serves a population of 3,112 and is classified as a small agglomeration under EU regulations. It is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity of 10,000 m³/day indicates that the plant has capacity to accommodate future growth. The actual discharge volume is 636.88 m³/day, suggesting a utilization rate well below capacity. The treated effluent from COV Poltar is discharged into a local receiving water body, which ultimately drains into the broader Danube basin. The plant plays a key role in protecting the water quality of local streams and rivers, supporting the ecological health of the region's freshwater systems.

COV Poltar discharges into a local watercourse that is part of the Danube River basin, which flows into the Black Sea. The plant's secondary treatment helps reduce organic pollutants and nutrients, protecting downstream aquatic habitats. The region's water bodies support diverse fish populations and are important for local biodiversity, though specific protected areas are not confirmed.
