COV Udica Centrum Wastewater Treatment Plant, Udiča, Slovakia

COV Udica Centrum is a municipal wastewater treatment plant located in Udiča, a village in the Trenčiansky kraj region of western Slovakia. The plant serves a small population of 300 residents, reflecting its role in a rural community. It operates under the regulatory framework of the Slovak Republic, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, a standard requirement for agglomerations of this size under EU regulations. Its designed capacity is 300 m³/day, with an actual discharge volume of 61.40 m³/day, indicating operational headroom. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local watercourse that ultimately drains into the Váh River basin, part of the Danube River system flowing into the Black Sea. The plant's operation helps protect the ecological health of the Váh River and downstream aquatic habitats.

The plant discharges into a tributary of the Váh River, which flows into the Danube River and eventually reaches the Black Sea. The Váh River supports diverse aquatic life and is an important ecological corridor in the Carpathian region. The plant's secondary treatment reduces nutrient loads, helping to prevent eutrophication in downstream waters.
