COV Udica I Wastewater Treatment Plant, Udiča, Slovakia

COV Udica I is a wastewater treatment plant located in Udiča, a village in the Trenčiansky kraj region of western Slovakia. The plant serves a small population of 74 people, reflecting its role in a rural community. It is situated inland, far from coastal areas, and operates under Slovak national regulations that implement EU directives. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity is 140 m³/day, with an actual discharge volume of 15.14 m³/day, indicating ample capacity for current loads. Secondary treatment typically involves biological oxidation and settling. The treated effluent is discharged into a local watercourse, likely a tributary of the Váh River, which flows into the Danube River and eventually the Black Sea. The plant helps protect the local watershed and downstream ecosystems from untreated sewage, supporting water quality in the region.

The plant discharges into a local stream that is part of the Váh River basin, a major tributary of the Danube. The Danube flows into the Black Sea, making this plant part of a large international watershed. The surrounding area is characterized by forested hills and agricultural land, and the watercourse supports diverse aquatic life. Proper treatment is essential to prevent nutrient pollution and maintain ecological balance in this sensitive river system.
