COV Postrelmov Wastewater Treatment Plant, Postřelmov, Olomoucký kraj

COV Postrelmov is a municipal wastewater treatment facility located in Postřelmov, a town in the Olomoucký kraj region of the Czech Republic. The plant serves a population of approximately 3,315 residents and has a designed capacity of 6,300 cubic meters per day, with an average discharge volume of 456.81 m³/day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. This directive mandates secondary biological treatment to reduce organic matter and suspended solids before discharge into receiving waters. The treated effluent is discharged into local watercourses that eventually drain into the Morava River basin, a tributary of the Danube. The plant plays a key role in protecting the region's water quality and supporting downstream ecosystems in the Danube catchment.

The plant discharges into the Morava River basin, which flows into the Danube River and ultimately reaches the Black Sea. The local watershed supports diverse aquatic life and is part of an important migratory corridor for fish species. The secondary treatment provided by the plant helps reduce nutrient and organic pollution, safeguarding the ecological health of the downstream water bodies.
