The plant discharged into tributaries of the Elbe River, which flows through Germany and into the North Sea. The local watershed includes small streams and rivers that support aquatic habitats and are part of the larger Elbe basin. The area is inland, with no direct coastal influence, and the treated effluent contributed to the water quality of downstream environments.
