The plant discharges treated wastewater into local streams that flow into the Main River, a key tributary of the Rhine. The Rhine basin is a major European watershed supporting diverse aquatic species and providing critical habitat for migratory fish. Secondary treatment reduces organic load and nutrients, helping to maintain water quality in this ecologically sensitive river system.
