SKA BERGATREUTE - Advanced Wastewater Treatment Plant in Bergatreute, Germany

SKA BERGATREUTE is an advanced wastewater treatment facility located in Bergatreute, a municipality in the Ravensburg district of Baden-Württemberg, Germany. The plant serves a population of around 3,750 and has a designed capacity of 5,000 cubic meters per day, with an average discharge volume of 949.89 m³/day. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants in sensitive catchment areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment, and Germany often implements stricter standards to protect water quality. The plant discharges treated effluent into local watercourses that ultimately drain into the Danube River basin via the Schussen River and Lake Constance (Bodensee). This region is ecologically significant, supporting diverse aquatic life and serving as a critical water resource for the Upper Rhine Valley. The advanced treatment helps minimize nutrient loading into these sensitive waters.

The treated effluent from SKA BERGATREUTE flows into local streams that are part of the Schussen River catchment, which drains into Lake Constance (Bodensee). Lake Constance is a major drinking water reservoir and an ecologically sensitive ecosystem supporting diverse fish and bird species. The advanced treatment at this plant reduces nutrient pollution, helping to prevent eutrophication in the lake and downstream along the Rhine River.
