COV Mojmirovce Wastewater Treatment Plant, Mojmírovce, Slovakia

COV Mojmirovce is a municipal wastewater treatment plant located in Mojmírovce, a village in the Nitriansky kraj region of western Slovakia. The plant serves a population of approximately 1,778 residents and is part of the region's water management infrastructure. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,670 m³/day and an average daily discharge of 363.87 m³/day, the plant operates well below its capacity, indicating room for future growth. The treated effluent is discharged into local waterways that ultimately drain into the Danube River basin, contributing to the Black Sea watershed. The plant plays a key role in protecting local water quality and supporting the ecological health of the surrounding agricultural landscape.

The plant discharges into the Nitra River catchment, a tributary of the Váh River, which flows into the Danube River and eventually reaches the Black Sea. The region is predominantly agricultural, and the plant helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream water bodies. The local watershed supports diverse aquatic life and is important for irrigation and recreation.
