Grossbreitenbach Wastewater Treatment Plant, Thüringen, Germany

The Grossbreitenbach wastewater treatment plant is located in the town of Großbreitenbach, Thüringen, Germany. It serves a population of 2,588 and is classified as a small-scale municipal facility. The plant is situated in the Thuringian Forest region, an area characterized by its hilly terrain and forested landscape. The plant employs advanced treatment processes, which go beyond the secondary treatment requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). With a designed capacity of 4,850 m³/day and an average discharge volume of 869.68 m³/day, the facility operates well below its capacity, indicating room for future growth. The advanced treatment likely includes nutrient removal to protect sensitive receiving waters. The treated effluent is discharged into local watercourses that eventually drain into the Saale River, a major tributary of the Elbe River, which flows into the North Sea. The plant plays a crucial role in protecting the water quality of these rivers and the downstream ecosystem, including the Elbe estuary and the Wadden Sea, a UNESCO World Heritage site.

The plant discharges into small streams in the Thuringian Forest, which flow into the Ilm River, a tributary of the Saale. The Saale joins the Elbe, which empties into the North Sea. The region's forests and rivers support diverse aquatic life, including fish species like brown trout and grayling. Advanced treatment helps minimize nutrient loading, protecting downstream waters from eutrophication.
