SKA Apflau Wastewater Treatment Plant, Tettnang, Baden-Württemberg

SKA Apflau is a municipal wastewater treatment plant located in the Apflau district of Tettnang, in the Bodenseekreis region of Baden-Württemberg, Germany. The plant serves a population of about 6,200 people, placing it in the small to medium agglomeration category under EU regulations. As a German plant, SKA Apflau is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousand cubic meters per day or similar units), indicating its scale. Treatment processes and operational details are managed in accordance with national and EU standards. The plant discharges treated wastewater into the local watershed, which ultimately drains into Lake Constance (Bodensee), one of Europe's largest lakes. Lake Constance is a critical freshwater resource and supports diverse aquatic life. The plant's operations help protect the lake's water quality and the downstream Rhine River system.

SKA Apflau discharges into the catchment of Lake Constance (Bodensee), which is part of the Rhine River basin. The lake is a major drinking water reservoir and supports a rich ecosystem, including fish species like whitefish and perch. The plant's treatment helps prevent nutrient pollution that could cause algal blooms and degrade water quality in this sensitive freshwater environment.
