Rohr Wastewater Treatment Plant, Leuzdorf, Bavaria, Germany

Rohr wastewater treatment plant is located in Leuzdorf, a district of Rohr in the Landkreis Roth, Bavaria, Germany. The plant serves a population of approximately 8,869 people and operates with advanced treatment processes, ensuring high-quality effluent before discharge. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced (tertiary) treatment for sensitive areas. The plant's designed capacity of 2,800 cubic meters per day indicates it is sized for a moderate agglomeration, and its current discharge volume of 495.83 cubic meters per day suggests operational flexibility. The treated effluent is discharged into local water bodies that ultimately drain into the Rhine River basin, contributing to the overall water quality management of the region. The advanced treatment helps protect downstream ecosystems and supports the ecological health of the receiving waters.

The plant discharges into local streams that flow into the Rednitz River, a tributary of the Regnitz and Main rivers, eventually reaching the Rhine River and the North Sea. The surrounding region in Bavaria includes agricultural and forested areas, and the advanced treatment helps minimize nutrient loading, protecting aquatic life and supporting biodiversity in the downstream water bodies.
