COV Komjatice Wastewater Treatment Plant, Komjatice, Slovakia

COV Komjatice is a municipal wastewater treatment plant located in Komjatice, a village in the Nitriansky kraj region of western Slovakia. The plant serves a population of approximately 1,431 people and is part of the local infrastructure managed under Slovak national regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the standard required by the EU directive for agglomerations of this size. Its designed capacity of 7,000 m³/day indicates a significant buffer for future growth or seasonal variations. The actual discharge volume is 292.86 m³/day, suggesting the plant operates well below its maximum capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Danube River basin via the Nitra River. The Danube River flows into the Black Sea, making this plant part of a large transboundary river system that supports diverse aquatic ecosystems and provides water for millions of people downstream.

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. This watershed supports agricultural activities and provides habitat for fish species such as carp and pike. The region's flat terrain and intensive farming mean that nutrient removal from wastewater is important to prevent eutrophication in downstream water bodies.
