COV Loket Wastewater Treatment Plant, Loket, Karlovarský kraj

COV Loket is a municipal wastewater treatment facility located in Loket, a town in the Karlovarský kraj region of the Czech Republic. The plant serves a population of approximately 1,375, classifying it as a small agglomeration under Czech and EU regulations. It is situated inland, away from coastal areas, and its operations are part of the region's water management infrastructure. The plant provides secondary treatment, which is the standard level required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies from agglomerations of this size. The designed capacity of 3,984 cubic meters per day indicates the plant is built to handle higher loads, with current discharge volumes around 440 cubic meters per day, suggesting ample reserve capacity. The plant operates under Czech national regulations that implement EU directives, ensuring compliance with effluent quality standards. Treated effluent from COV Loket is discharged into the local water system, which ultimately drains into the Ohře River, a major tributary of the Elbe River. The Ohře River flows through western Czech Republic and into Germany, supporting diverse aquatic life and providing water for various uses. The plant's operations help protect the water quality of this river system, which is important for both ecological health and downstream communities.

COV Loket discharges treated wastewater into the local watershed, which feeds into the Ohře River. The Ohře River flows through the Karlovarský kraj region and joins the Elbe River in Germany, eventually reaching the North Sea. This river system supports a variety of fish species and provides habitat for aquatic invertebrates. The plant's secondary treatment helps reduce organic pollutants and nutrients, protecting the ecological balance of the Ohře River and its downstream environments.
