COV Valaska Wastewater Treatment Plant, Hronec, Slovakia

COV Valaska is a municipal wastewater treatment plant located in Hronec, within the Banskobystrický kraj region of central Slovakia. The facility serves a population of approximately 2,207 people and is part of the region's water infrastructure. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,700 m³/day and a reported discharge volume of 451.67 m³/day, the plant operates well within its capacity. The treated effluent is discharged into local waterways that ultimately drain into the Hron River basin, a tributary of the Danube. This river system supports diverse aquatic life and is important for regional water quality. The plant's operation helps protect downstream ecosystems and water resources.

The plant discharges into the Hron River basin, which flows into the Danube River and eventually the Black Sea. The Hron River supports a variety of fish species and is an important ecological corridor in central Slovakia. Protecting water quality in this basin is essential for maintaining biodiversity and supporting downstream communities.
