SKA NEUFRA Wastewater Treatment Plant, Rottweil, Baden-Württemberg

SKA NEUFRA is a municipal wastewater treatment plant located in the Neufra district of Rottweil, Baden-Württemberg, Germany. The plant serves an estimated population of 35,950, placing it in the medium agglomeration category under EU classification. As a German facility, SKA NEUFRA is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. German implementation through the Abwasserverordnung (Wastewater Ordinance) sets strict effluent standards for parameters such as BOD, COD, nitrogen, and phosphorus. The plant discharges treated effluent into the local water system, which ultimately drains into the Neckar River basin. The Neckar flows into the Rhine River, a major European waterway that supports diverse aquatic life and provides drinking water for millions. The plant's operation helps protect the water quality of this important river system.

The treated effluent from SKA NEUFRA enters the Neckar River basin, which flows through Baden-Württemberg before joining the Rhine River. The Rhine is a critical ecological corridor supporting migratory fish species and diverse aquatic habitats. The plant's location in the upper Neckar watershed means its discharge quality directly affects downstream water uses, including drinking water abstraction and recreation.
