COV Vesele Wastewater Treatment Plant, Veselé, Slovakia

COV Vesele is an advanced wastewater treatment plant located in Veselé, a village in the Trnavský kraj region of western Slovakia. The plant serves a population of approximately 1,139 residents, making it a small-scale municipal facility. Its designed capacity of 1,440 m³/day indicates it is sized to handle local domestic wastewater flows. As an advanced treatment plant, COV Vesele goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for facilities discharging into sensitive water bodies under the EU Urban Waste Water Treatment Directive (91/271/EEC). The advanced classification suggests the plant employs tertiary filtration or biological nutrient removal. The plant's discharge volume of 233.10 m³/day reflects current operational levels. The treated effluent from COV Vesele ultimately drains into the Váh River basin, a major tributary of the Danube River. The Váh River flows into the Danube, which then reaches the Black Sea. This downstream connection highlights the plant's role in protecting the water quality of the Váh and Danube ecosystems, which support diverse aquatic life and are important for regional biodiversity.

COV Vesele discharges treated wastewater into the local watershed, which drains into the Váh River, a major tributary of the Danube River. The Danube flows into the Black Sea, making this plant part of a large international basin. The Váh River supports diverse aquatic habitats and is an important migratory corridor for fish species. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality and preventing eutrophication in sensitive areas.
