SKA Kirchheim Kirchheim Wastewater Treatment Plant, Dirgenheim, Baden-Württemberg

SKA Kirchheim Kirchheim is a wastewater treatment plant located in Dirgenheim, a district of Kirchheim am Ries in the Ostalbkreis district of Baden-Württemberg, Germany. The plant serves a population of approximately 2,600 people and has a designed capacity of 2,000 cubic meters per day, with a discharge volume of 658 cubic meters per day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a German facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for agglomerations discharging into sensitive areas. The plant's advanced treatment level aligns with the directive's standards for protecting water quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhine River basin. The plant's location inland and its advanced treatment help safeguard downstream aquatic ecosystems, including the Rhine and its tributaries, which support diverse fish and invertebrate populations.

The plant discharges into the local watershed within the Rhine River basin, which flows through Germany and the Netherlands into the North Sea. The Rhine is a major European waterway supporting diverse aquatic life, including salmon and eel populations. The advanced treatment at this plant helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream waters.
