COV Usti nad Labem Strekov - Secondary Wastewater Treatment Plant in Ústí nad Labem, Czech Republic

COV Usti nad Labem Strekov is a municipal wastewater treatment plant located in Ústí nad Labem, a city in the Ústecký kraj region of the Czech Republic. The plant serves a small population of 308 and has a designed capacity of 2,500 m³/day, with a current discharge volume of 119.73 m³/day, indicating low utilization relative to capacity. 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. While the directive mandates secondary treatment for all discharges from agglomerations above 2,000 population equivalent, smaller plants like this one are still expected to meet appropriate treatment standards to protect receiving waters. The treated effluent is discharged into the local water system, which ultimately drains into the Elbe River (Labe), a major Central European waterway that flows through Germany to the North Sea. The plant's operation contributes to maintaining water quality in the Elbe basin, supporting aquatic ecosystems and downstream uses.

The plant discharges into the Elbe River basin, which flows through the Czech Republic and Germany before reaching the North Sea. The Elbe is a critical waterway for biodiversity, supporting fish species such as salmon and sturgeon, and providing habitat for migratory birds. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water quality in this ecologically sensitive river system.
