COV Cabaj Capor Wastewater Treatment Plant, Cabaj-Čápor, Nitriansky kraj

COV Cabaj Capor is a municipal wastewater treatment plant located in Cabaj-Čápor, Nitriansky kraj, Slovakia. The facility serves a population of approximately 2,086 people, classifying it as a small agglomeration under Slovak and EU regulations. The plant is situated in the Nitra region, an inland area with agricultural and residential catchments. The plant provides secondary treatment, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity is 2,550 m³/day, with a current discharge volume of 426.91 m³/day, indicating operational capacity well below design limits. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. Treated effluent 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 eventually the Black Sea. The plant plays a key role in protecting local streams and the broader Danube basin from untreated wastewater pollution, supporting aquatic life and downstream water quality.

The plant discharges into small streams that feed the Nitra River, part of the Váh-Danube basin. This inland watershed supports diverse aquatic ecosystems and is important for agriculture and biodiversity in western Slovakia. The Danube River, into which the basin drains, is a major European waterway with significant ecological and economic value. Protecting these waters from nutrient and organic pollution is critical for maintaining water quality and habitat health.
