COV Kralovsky Chlmec - Secondary Wastewater Treatment Plant in Kráľovský Chlmec, Slovakia

COV Kralovsky Chlmec is a municipal wastewater treatment plant located in Kráľovský Chlmec, a town in the Košický kraj region of eastern Slovakia. The plant serves a population of approximately 3,885 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 7,000 m³/day and a current discharge volume of about 795 m³/day, the plant operates well below its capacity, indicating room for future growth. Treated effluent from the plant is discharged into local watercourses that eventually drain into the Tisza River basin, a major tributary of the Danube. This region supports diverse aquatic ecosystems and is important for migratory fish species. The plant's operation helps protect downstream water quality in the Tisza and Danube river systems.

The plant discharges into local streams that flow into the Tisza River, a major tributary of the Danube. The Tisza basin supports diverse aquatic life, including fish species such as carp and pike, and provides important habitat for migratory birds. The Danube River ultimately carries the water to the Black Sea, making the plant's treatment crucial for regional water quality.
