COV Celadna Wastewater Treatment Plant, Čeladná, Moravskoslezský kraj

COV Celadna is a municipal wastewater treatment plant located in the village of Čeladná, in the Moravskoslezský region of the Czech Republic. The plant serves a population of 1,251 and has a designed capacity of 4,000 m³/day, indicating it is sized for future growth or seasonal peaks. The plant provides secondary treatment, which is the standard required under Czech and EU regulations for agglomerations of this size. The EU Urban Waste Water Treatment Directive (91/271/EEC) mandates secondary treatment for all discharges from agglomerations above 2,000 population equivalent, and Čeladná falls below this threshold, yet the plant still meets secondary treatment standards. The treated wastewater is discharged into a local watercourse that ultimately drains into the Odra River basin, which flows to the Baltic Sea. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems from nutrient pollution.

The plant discharges into a small stream in the Moravskoslezský region, part of the Odra River basin. The Odra River flows through the Czech Republic, Poland, and Germany before reaching the Baltic Sea. The local watershed supports diverse aquatic life and is an important ecological corridor. Secondary treatment helps reduce organic load and nutrients, protecting downstream water quality.
