COV Dvur Kralove nad Labem Wastewater Treatment Plant, Dvůr Králové nad Labem

COV Dvur Kralove nad Labem is a municipal wastewater treatment plant located in Dvůr Králové nad Labem, in the Královéhradecký kraj region of the Czech Republic. The plant serves a population of approximately 17,574, classifying it as a medium-sized agglomeration under EU regulations. As a Czech facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are sensitive to eutrophication. The regulatory framework ensures compliance with European standards. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Elbe River basin. The Elbe flows through Germany to the North Sea, supporting diverse aquatic ecosystems and serving as an important migratory corridor for fish species. The plant plays a key role in protecting water quality in this transboundary river system.

The plant's treated effluent enters the local tributary network of the Elbe River, which flows through the Czech Republic and Germany before reaching the North Sea. The Elbe basin supports diverse aquatic life, including salmonid populations, and is an important ecological corridor. Downstream areas include sensitive floodplain habitats that benefit from effective nutrient removal to prevent eutrophication.
