The region is part of the Baltic Sea catchment, which is sensitive to nutrient pollution, making secondary treatment important for protecting coastal and marine ecosystems.
Environmental context
The plant discharges into the Parsęta River basin, which flows northward into the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it vulnerable to eutrophication from nutrient inputs. The secondary treatment at Bonin helps reduce organic load and nutrients, supporting the ecological health of downstream rivers and the coastal zone.
