SKA Oberohrn Wastewater Treatment Plant, Oberohrn, Germany

SKA Oberohrn is a former wastewater treatment plant located in Oberohrn, a district of Pfedelbach in the Hohenlohekreis district of Baden-Württemberg, Germany. The plant served the local community before its closure, with a designed capacity of 6,000 cubic meters per day. As a secondary treatment facility, it provided biological treatment to reduce organic pollutants and suspended solids. The plant operated under the German wastewater regulations, which implement the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this scale, secondary treatment is the standard requirement. The plant's closure may reflect consolidation of wastewater services in the region, as larger regional plants often replace smaller facilities to improve efficiency and meet stricter environmental standards. The treated effluent from SKA Oberohrn would have discharged into a local watercourse within the Neckar River basin, which ultimately flows into the Rhine River and then the North Sea. The plant's operation contributed to protecting the local watershed from untreated sewage, supporting water quality in the sensitive Rhine ecosystem.

The plant's discharge would have entered a small tributary of the Neckar River, part of the Rhine basin that drains into the North Sea. The Rhine is a major European waterway supporting diverse aquatic life and providing drinking water for millions. The plant's secondary treatment helped reduce nutrient loads, protecting downstream ecosystems from eutrophication.
