COV Ilava Wastewater Treatment Plant - Ilava, Trenčiansky kraj, Slovakia

COV Ilava is a municipal wastewater treatment plant located in Ilava, within the Trenčiansky kraj region of western Slovakia. The plant serves a population of approximately 3,076 people, classifying it as a small agglomeration under EU standards. It is situated near the D1 highway in the recreational zone of Ilava, providing essential sanitation services to the local community. The plant operates with secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Its designed capacity is 7,000 m³/day, with an actual discharge volume of 629.51 m³/day, indicating significant spare capacity. The facility is part of Slovakia's national wastewater infrastructure, regulated under the country's transposition of EU directives. The treated effluent from COV Ilava is discharged into the local watershed, which ultimately drains into the Váh River, a major tributary of the Danube River. The Váh River flows through western Slovakia before joining the Danube, which then empties into the Black Sea. This downstream connection highlights the plant's role in protecting the water quality of the Váh River and the broader Danube basin.

COV Ilava discharges into the local watershed that feeds the Váh River, a significant watercourse in western Slovakia. The Váh River flows into the Danube River, which ultimately reaches the Black Sea. The plant's secondary treatment helps reduce organic pollutants and suspended solids, protecting aquatic life in the Váh River and downstream ecosystems. The region supports diverse freshwater habitats, including fish spawning grounds and migratory bird corridors along the Danube floodplains.
