COV Kosicka Nova Ves Wastewater Treatment Plant, Košice, Slovakia

COV Kosicka Nova Ves is a municipal wastewater treatment plant located in the Košická Nová Ves district of Košice, Slovakia. It serves a small population of 646 residents, reflecting its role as a local facility for this suburban area within the larger Košice metropolitan region. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2000 m³/day and an actual discharge volume of 132.21 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into the local watershed, which ultimately drains into the Hornád River basin and then into the Tisza River, a major tributary of the Danube. This connection to the Danube-Black Sea system underscores the plant's role in protecting downstream water quality in a transboundary river basin.

The plant discharges into the Hornád River catchment, which flows into the Tisza River and eventually the Danube River before reaching the Black Sea. This transboundary basin supports diverse aquatic life and is an important ecological corridor in Central Europe. The secondary treatment provided helps reduce organic pollution and nutrient loads, protecting downstream water quality in a region where agricultural and industrial pressures exist.
