Environmental context
The plant discharges into the Odra River basin, which flows through western Poland and into the Szczecin Lagoon before reaching the Baltic Sea. The Baltic Sea is a semi-enclosed sea sensitive to eutrophication from nutrient pollution. Advanced treatment at this plant helps reduce nitrogen and phosphorus loads, mitigating algal blooms and supporting marine biodiversity.
