Overview
COV Zilina is a wastewater treatment plant serving approximately 118,000 people in Kotešová, Slovakia. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
COV Zilina is a municipal wastewater treatment plant located in Kotešová, a village in the Žilinský kraj region of Slovakia. The plant serves a population of approximately 117,841, classifying it as a large agglomeration under EU regulations. It is situated in the Váh River basin, a major waterway in northern Slovakia. As a large agglomeration, COV Zilina is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment as a minimum. For plants serving over 100,000 people in sensitive areas, tertiary treatment may be necessary to reduce nutrient loads. Regulatory compliance ensures appropriate treatment standards. The treated effluent from COV Zilina is discharged into the Váh River, which flows southwest through Slovakia and eventually into the Danube River near Komárno. The Váh River supports diverse aquatic life and is an important migratory corridor for fish species. The plant's operations help protect downstream water quality in the Danube basin.
Environmental context
COV Zilina discharges into the Váh River, a tributary of the Danube River, which ultimately flows into the Black Sea. The Váh River basin supports a variety of freshwater habitats and is ecologically sensitive due to its role in regional biodiversity. The plant's treatment helps mitigate nutrient pollution that could otherwise contribute to eutrophication in downstream water bodies.
