COV Ostravice Wastewater Treatment Plant, Ostravice, Moravskoslezský kraj

COV Ostravice is a municipal wastewater treatment plant located in the village of Ostravice, within the Moravskoslezský kraj of the Czech Republic. The plant serves a population of approximately 4,352 residents, classifying it as a small agglomeration under EU guidelines. It operates under the Czech national regulations that implement the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the standard required for discharges into freshwater bodies in the region. With a designed capacity of 4,000 m³/day and an actual discharge volume of 246.51 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treatment process likely involves biological treatment followed by sedimentation, typical for secondary plants of this scale. The treated effluent is discharged into the Ostravice River, a tributary of the Odra River basin. The Odra River flows northward through Poland and eventually reaches the Baltic Sea. The plant plays a crucial role in protecting the water quality of the Ostravice River and downstream ecosystems, including the Odra River and the Baltic Sea coastal zone.

The Ostravice River flows through the Moravian-Silesian Beskids and joins the Odra River, which drains into the Baltic Sea via Poland. The watershed supports diverse aquatic life, including fish species such as brown trout and grayling. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting the river's ecological health and downstream water bodies from eutrophication.
