COV Nove Zamky Wastewater Treatment Plant, Nové Zámky, Slovakia

COV Nove Zamky is a municipal wastewater treatment plant located in Nové Zámky, a town in the Nitriansky kraj region of western Slovakia. The plant serves a population of approximately 42,715, classifying it as a medium-sized agglomeration under EU standards. Its location inland, about 50 km from the Danube River, places it within the broader Danube basin. As a Slovak facility, COV Nove Zamky operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The directive also requires more advanced treatment if the receiving waters are designated as sensitive areas. Compliance with national regulations ensures a standard level of treatment appropriate for the population served. The treated effluent from COV Nove Zamky is discharged into local waterways that ultimately flow into the Danube River, a major European watercourse. The Danube supports diverse aquatic ecosystems and provides drinking water for millions. Proper treatment at this plant helps protect downstream water quality in the Danube basin, including ecologically sensitive areas such as floodplain forests and wetlands.

COV Nove Zamky discharges into local streams that drain into the Danube River, which flows through Slovakia into Hungary and eventually the Black Sea. The Danube basin supports a rich array of aquatic life, including fish species like sturgeon and migratory birds. The plant's treatment helps maintain water quality in this ecologically significant river system, which is vital for biodiversity and human use downstream.
