COV Loucna u Lomu Wastewater Treatment Plant, Lom, Czech Republic

COV Loucna u Lomu is a wastewater treatment plant located in the Ústecký kraj region of the Czech Republic, serving the small community of Lom. The plant provides secondary treatment for a population of 513, with a designed capacity of 800 m³/day and an average discharge volume of 169.33 m³/day. As a secondary treatment facility, the plant meets the minimum standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent (PE) between 2,000 and 10,000, though smaller plants like this one are also expected to provide appropriate treatment to protect local water quality. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the North Sea via the Elbe River basin. The region's water bodies support diverse aquatic life and are important for both ecological balance and human use, making proper wastewater treatment essential for maintaining water quality.

The plant discharges into the local watershed within the Elbe River basin, which flows through the Czech Republic and Germany before reaching the North Sea. The downstream environment includes sensitive aquatic habitats that rely on adequate wastewater treatment to prevent nutrient enrichment and maintain biodiversity. The region's water bodies support fish populations and other aquatic organisms, making secondary treatment crucial for ecological health.
