COV Halic Wastewater Treatment Plant, Halič, Banskobystrický kraj

COV Halic is a municipal wastewater treatment plant located in Halič, a village in the Lučenec District of Banskobystrický kraj, central Slovakia. The plant serves a population of 1,107 and is classified as a small agglomeration under Slovak and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 1,540 m³/day and an average discharge volume of 226.55 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local waterways that ultimately drain into the Ipeľ River basin, a tributary of the Danube. The Danube flows into the Black Sea, making this plant part of a transboundary river system that supports diverse aquatic ecosystems and provides water for agriculture and communities downstream.

The plant discharges into the Ipeľ River basin, which flows into the Danube River and eventually the Black Sea. This watershed supports diverse aquatic life and is an important ecological corridor in central Europe. The advanced treatment level helps protect downstream water quality, particularly in sensitive areas where nutrient reduction is critical to prevent eutrophication.
