COV Velke Zaluzie Wastewater Treatment Plant, Lehota, Nitriansky kraj, Slovakia

COV Velke Zaluzie is a municipal wastewater treatment plant located in Lehota, near Veľké Zálužie, in the Nitriansky kraj region of western Slovakia. The plant serves the local community as part of the region's wastewater infrastructure, contributing to public health and environmental protection in the Nitra River basin. The plant provides secondary treatment, a standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this scale. With a designed capacity of 4300 m³/day, it is sized to handle the wastewater generated by the surrounding population. The facility operates within Slovakia's national regulatory framework, which transposes EU directives into local law. Treated effluent from the plant is discharged into local watercourses that ultimately drain into the Nitra River, a tributary of the Váh River, which flows into the Danube River and then the Black Sea. The plant plays a key role in protecting downstream water quality and aquatic ecosystems in this important Central European watershed.

The plant discharges into local streams that feed the Nitra River, part of the Váh-Danube basin. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream. The Danube River, into which these waters eventually flow, is a major European waterway with significant ecological importance, hosting numerous fish species and migratory birds. Protecting water quality in this basin is critical for maintaining biodiversity and ensuring safe water resources.
