COV Uvaly Wastewater Treatment Plant, Brtnice, Central Bohemia

COV Uvaly is a secondary wastewater treatment facility located in Brtnice, within the Central Bohemian Region (Středočeský kraj) of the Czech Republic. The plant serves a population equivalent of about 6,942 people, placing it in the small-to-medium agglomeration category under Czech and EU regulations. Its designed capacity of 6,048 m³/day indicates it is sized to handle typical domestic flows from the local community. As a secondary treatment plant, COV Uvaly employs biological processes to reduce organic matter and suspended solids, meeting the standards required by 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 above 2,000 population equivalent, which this plant complies with. The plant's discharge volume of 838.65 m³/day reflects current operational flows. The treated effluent from COV Uvaly is discharged into local watercourses that ultimately drain into the Elbe River basin, which flows through Germany to the North Sea. The plant plays a key role in protecting the water quality of small streams in the region, supporting aquatic life and downstream ecosystems. Its location inland, away from coastal areas, reduces direct marine impact but emphasizes the importance of maintaining river health.

COV Uvaly discharges treated wastewater into local streams that are part of the Elbe River basin. The Elbe flows through the Czech Republic and Germany before reaching the North Sea, making the plant's performance important for downstream water quality. The receiving waters support diverse aquatic life and are used for recreation and agriculture. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream reservoirs and the Elbe estuary.
