COV Krasno nad Kysucou - Advanced Wastewater Treatment in Krásno nad Kysucou, Slovakia

COV Krasno nad Kysucou is a wastewater treatment facility located in the town of Krásno nad Kysucou, within the Čadca District of Žilinský kraj in northern Slovakia. The plant serves a population of about 3,928 residents, placing it in the small agglomeration category under EU classification. 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 8,670 m³/day and a current discharge volume of 803.88 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Kysuca River, a tributary of the Váh River. The Váh flows into the Danube River, which empties into the Black Sea. The plant plays a key role in protecting the water quality of the Kysuca River and downstream ecosystems.

The plant discharges into the Kysuca River basin, which flows into the Váh River, a major tributary of the Danube. The Danube carries water to the Black Sea, making this plant part of a large transboundary watershed. The Kysuca River supports diverse aquatic life and is an important corridor for fish migration. Advanced treatment helps minimize nutrient loading and protects downstream water quality in the Danube Delta ecosystem.
