GEISELBACH Wastewater Treatment Plant, Omersbach, Bayern, Germany

The GEISELBACH wastewater treatment plant is located in Omersbach, within the Geiselbach municipality in the Landkreis Aschaffenburg, Bayern, Germany. It served a population of 1,300, classifying it as a small agglomeration under German and EU regulations. As an advanced treatment facility, it likely employed processes such as nutrient removal or disinfection beyond secondary treatment. The plant had a designed capacity of 2,200 cubic meters per day, with a discharge volume of 329 cubic meters per day. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this are generally required to provide secondary treatment, but advanced treatment may be mandated in sensitive areas. The plant's discharge ultimately drains into the local watershed, which is part of the Rhine-Main river system. The region's water bodies support diverse aquatic life and are important for regional ecology.

The plant's treated effluent would have entered the local stream network, eventually reaching the Main River, a major tributary of the Rhine. The Rhine basin is ecologically significant, supporting migratory fish species and diverse aquatic habitats. The region's water quality is regulated under the EU Water Framework Directive, aiming for good ecological status.
