COV Nova Bana Tajch Wastewater Treatment Plant, Nová Baňa, Slovakia

COV Nova Bana Tajch is a municipal wastewater treatment plant located in Nová Baňa, within the Banskobystrický kraj region of central Slovakia. The plant serves a small population and operates under the national regulatory framework aligned with the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the standard required by the EU directive for freshwater discharges from agglomerations of this scale. With current discharge volume at 2.25 m³/day. The treated effluent is discharged into a local watercourse that ultimately drains into the Hron River basin, a tributary of the Danube. The Danube flows into the Black Sea, making this plant part of a large international watershed. The surrounding area is characterized by forested hills and agricultural land, with the plant playing a role in protecting local streams and downstream aquatic ecosystems.

The plant discharges into a local stream that flows into the Hron River, a major tributary of the Danube. The Danube carries water through several countries to the Black Sea, making this plant part of a transboundary watershed. The region supports diverse aquatic life, including fish species that rely on clean water for spawning. Secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream habitats.
