Overview
Rothenbach wastewater treatment plant in Röthenbach (Allgäu), Bavaria, Germany, serves 1,600 people with advanced treatment. The plant is closed but historically discharged 404.92 m³/day with a design capacity of 3,116 m³/day.
Rothenbach is a former wastewater treatment plant located in Röthenbach (Allgäu), a municipality in the Bavarian district of Lindau, Germany. The plant served a population of approximately 1,600 people and was designed to handle a capacity of 3,116 m³ per day, with an average discharge volume of 404.92 m³ per day. It operated with advanced treatment processes, reflecting high environmental standards. As a German facility, the plant was subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations above 2,000 population equivalent and more stringent treatment for sensitive areas. Although the plant is now closed, its advanced treatment level indicates compliance with German wastewater regulations, which often require nutrient removal for inland waters. The treated effluent from Rothenbach would have discharged into local watercourses that drain into the Rhine basin, ultimately reaching the North Sea. The plant's location in the Allgäu region, a headwater area for several rivers, underscores its role in protecting downstream aquatic ecosystems from nutrient pollution.
Environmental context
Rothenbach lies in the Allgäu region of Bavaria, a headwater area for streams feeding into the Rhine basin. The treated effluent would have entered local watercourses that flow into the Rhine River, which traverses several countries before reaching the North Sea. This watershed supports diverse aquatic life and is ecologically sensitive due to its alpine origins and downstream importance for drinking water and biodiversity.
