COV Dvorany nad Nitrou - Closed Wastewater Treatment Plant in Belince, Slovakia

COV Dvorany nad Nitrou is a former wastewater treatment plant located in Belince, a village in the Topoľčany district of Nitriansky kraj, western Slovakia. The plant provided secondary treatment for the local population before ceasing operations. As a secondary treatment facility, the plant would have met the standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary biological treatment for agglomerations of this scale. The plant's closure may reflect upgrades or consolidation of regional wastewater infrastructure. The plant's receiving waters are part of the Nitra River basin, which flows into the Váh River and ultimately the Danube River, draining into the Black Sea. The region supports diverse aquatic life and agricultural activities, making proper wastewater management important for water quality.

The plant is located inland in the Nitra River basin, part of the larger Danube catchment that drains into the Black Sea. The local watershed supports agricultural land and small watercourses that contribute to the Nitra River. Downstream ecosystems benefit from nutrient removal provided by secondary treatment, helping to reduce eutrophication risks in the Danube Delta.
