Environmental context
The plant discharges into local streams that flow into the Vistula River basin, eventually reaching the Baltic Sea. The Baltic Sea is a semi-enclosed, brackish sea with limited water exchange, making it sensitive to nutrient pollution. The plant's secondary treatment reduces organic load and helps mitigate eutrophication risks in downstream waters, supporting the ecological health of the region.
