COV Mosty u Jablunkova II Wastewater Treatment Plant, Mosty u Jablunkova, Czech Republic

COV Mosty u Jablunkova II is a municipal wastewater treatment plant located in the village of Mosty u Jablunkova in the Moravskoslezský kraj region of the Czech Republic. The plant serves a population of approximately 1,124 people, classifying it as a small agglomeration under Czech and EU regulations. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies from agglomerations of this size. Its designed capacity is 2,100 m³/day, with an actual discharge volume of 134.97 m³/day, indicating significant spare capacity. The treated effluent is discharged into local waterways that ultimately drain into the Odra River basin, which flows northward into the Baltic Sea. The plant plays a key role in protecting the water quality of the region's streams and rivers, supporting aquatic life and downstream ecosystems.

The plant discharges into the local watershed of the Olše River, a tributary of the Odra River. The Odra basin is ecologically important, supporting diverse aquatic habitats and migratory fish species. The region's mountainous terrain and forested areas contribute to sensitive water quality, making effective wastewater treatment essential for maintaining the ecological balance of the downstream rivers and the Baltic Sea.
