COV Karlovy Vary Drahonovice Wastewater Treatment Plant, Karlovy Vary, Czech Republic

COV Karlovy Vary Drahonovice is a municipal wastewater treatment plant located in the Drahovice district of Karlovy Vary, Czech Republic. The plant serves a population equivalent of 80,220, classifying it as a medium-to-large agglomeration under EU regulations. It is situated in the Karlovarský kraj region, near the Ohře River. As a plant of this scale in the Czech Republic, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations above 2,000 population equivalent and more stringent treatment in sensitive areas. The regulatory framework ensures compliance with national and EU standards. The plant discharges treated wastewater into the Ohře River, which flows into the Elbe River and eventually reaches the North Sea. This water body supports diverse aquatic life and is an important ecological corridor in the region. The plant plays a key role in protecting water quality in the Ohře basin and downstream environments.

The plant discharges into the Ohře River, a tributary of the Elbe River, which flows through Germany to the North Sea. The Ohře basin supports diverse aquatic ecosystems and is used for recreation and fishing. The plant's operations help maintain water quality in this transboundary river system, which is ecologically sensitive due to its role as a migratory corridor for fish and other aquatic species.
