COV Brno Modrice Wastewater Treatment Plant - Serving Brno Metropolitan Area

COV Brno Modrice is a large municipal wastewater treatment plant located in Modřice, Jihomoravský kraj, Czech Republic. It serves a population of over 416,000, classifying it as a large agglomeration under EU standards. The plant is part of the regional infrastructure for the Brno metropolitan area. As a facility serving more than 150,000 people, COV Brno Modrice is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment (tertiary) for discharges into sensitive areas. The plant's treatment processes are designed to meet these stringent standards, ensuring effective removal of nutrients and pollutants. The treated effluent from the plant is discharged into the Svratka River, which flows through Brno and eventually joins the Dyje River, a tributary of the Morava River, part of the Danube basin. This river system supports diverse aquatic life and is important for regional water quality and downstream ecosystems.

The plant discharges into the Svratka River, which flows through Brno and joins the Dyje River, part of the Morava River basin. This river system ultimately drains into the Danube River and the Black Sea. The Svratka River supports a variety of fish species and is used for recreation and irrigation downstream. Protecting water quality in this basin is critical for maintaining ecological balance and meeting EU Water Framework Directive goals.
