SKA Utzmemmingen Riesburg Wastewater Treatment Plant, Utzmemmingen, Germany

SKA Utzmemmingen Riesburg is a wastewater treatment plant located in Utzmemmingen, a district of Riesbürg in the Ostalbkreis region of Baden-Württemberg, Germany. The plant served a small community of approximately 1,600 people and was designed to handle up to 1,350 cubic meters of wastewater per day. As a secondary treatment facility, the plant provided biological treatment to reduce organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 2,000 and 10,000 are generally required to have secondary treatment. Although this plant served fewer than 2,000 people, it still met secondary treatment standards, reflecting Germany's stringent national implementation of the directive. The plant's discharge volume was approximately 405 m³/day, which would have been released into a local watercourse. The plant is now closed, and its wastewater is likely diverted to a larger regional facility. The surrounding area drains into the Danube River basin via the Eger River, a tributary of the Danube, which ultimately flows into the Black Sea.

The plant is situated in the Danube River basin, with local drainage likely flowing into the Eger River, a tributary of the Danube. The Danube is one of Europe's most important waterways, supporting diverse aquatic ecosystems and providing habitat for numerous fish species. The region's karst geology and agricultural land use require careful wastewater management to protect groundwater and surface water quality.
