COV Nemecka Wastewater Treatment Plant, Nemecká, Slovakia

COV Nemecka is a wastewater treatment facility located in the village of Nemecká, within the Brezno District of Banskobystrický kraj in central Slovakia. The plant serves a small population of 446 residents and is part of the municipal infrastructure for this rural community. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations under 2,000 population equivalent. With a designed capacity of 750 m³/day and an actual discharge volume of 91.28 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent from COV Nemecka is discharged into local watercourses that ultimately drain into the Hron River basin, a major tributary of the Danube. The Danube River flows into the Black Sea, making this plant part of a large international watershed. The advanced treatment helps protect downstream aquatic ecosystems, including sensitive habitats in the Danube Delta.

The plant discharges into local streams that feed the Hron River, a significant tributary of the Danube. The Danube flows through several countries before reaching the Black Sea, supporting diverse aquatic life and important migratory fish species. The advanced treatment level reduces nutrient and pollutant loads, helping to maintain water quality in this ecologically sensitive transboundary river system.
