COV Kopcany Wastewater Treatment Plant, Kopčany, Slovakia

COV Kopcany is a municipal wastewater treatment plant located in Kopčany, a village in the Skalica District of Trnavský kraj, western Slovakia. The plant serves a small population of 409 residents, reflecting its role in a rural community. It is situated near the Morava River, which forms the border with the Czech Republic. The plant provides secondary treatment, a standard level for small agglomerations under Slovak and EU regulations. With a designed capacity of 1,750 m³/day and an actual discharge volume of 83.70 m³/day, the plant operates well below its capacity, indicating it is sized for future growth or seasonal peaks. The facility is part of the national wastewater infrastructure managed under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for all agglomerations above 2,000 population equivalent, though smaller plants like this one are also expected to meet appropriate standards. The treated effluent is discharged into the Morava River basin, which flows into the Danube River near Bratislava, ultimately reaching the Black Sea. The plant's operation helps protect the Morava River's water quality, supporting aquatic life and downstream ecosystems in the Danube basin. Its inland location and small scale contribute to a low environmental footprint.

COV Kopcany discharges into the Morava River, a tributary of the Danube. The Morava River supports diverse aquatic habitats and is an important migratory corridor for fish species. The Danube River, into which the Morava flows, is a major European waterway that empties into the Black Sea, sustaining extensive wetlands and delta ecosystems. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting these downstream environments.
