Environmental context
The plant's discharge enters local streams that feed into the Warta River, a key tributary of the Oder River. The Oder basin supports diverse aquatic life and is an important migratory corridor for fish. The Baltic Sea, the ultimate receiving water body, is highly sensitive to eutrophication from nutrient loads, making effective wastewater treatment crucial for regional water quality.
