COV Kysucky Lieskovec - Wastewater Treatment Plant in Kysucké Nové Mesto, Slovakia

COV Kysucky Lieskovec is a municipal wastewater treatment plant located in the Škorčie area of Kysucké Nové Mesto, in the Žilinský kraj region of northern Slovakia. The plant serves a population of approximately 1,062 people, placing it in the small agglomeration category under Slovak and EU regulations. The facility provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The plant has a designed capacity of 2,800 m³ per day and currently discharges an average volume of 217.34 m³ per day, indicating it operates well below its design capacity. 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 then reaches the Black Sea. The plant plays a key role in protecting the water quality of these downstream water bodies.

The plant discharges into the Kysuca River basin, which flows into the Váh River, a major tributary of the Danube. The Danube carries water through Central and Eastern Europe to the Black Sea. The Kysuca River supports diverse aquatic life and is part of a sensitive freshwater ecosystem. Secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream habitats and water quality.
