The plant plays a key role in protecting the region's surface waters from eutrophication, supporting aquatic life and downstream ecosystems.
Environmental context
The plant discharges into the Oder River basin, which flows northward through western Poland and into the Baltic Sea via the Szczecin Lagoon. The Baltic Sea is a semi-enclosed, brackish sea highly sensitive to nutrient pollution, making advanced treatment crucial for preventing algal blooms and oxygen depletion. The local watershed supports diverse aquatic habitats and is part of a migratory corridor for fish species.
