SKA Königseggwald Wastewater Treatment Plant, Baden-Württemberg, Germany

SKA Königseggwald is a wastewater treatment plant located in Königseggwald, Baden-Württemberg, Germany. The facility served a population of 1,950 and had a designed capacity of 3,000 m³/day, with an average discharge volume of 493.50 m³/day. The plant is now closed. As a secondary treatment plant, it 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 typically require secondary treatment. Königseggwald's population of 1,950 falls below this threshold, but the plant still met secondary standards. The plant's discharge entered local watercourses that drain into the Danube River basin, eventually reaching the Black Sea. The surrounding region in Baden-Württemberg features a mix of agricultural and rural landscapes, with the plant playing a role in protecting local streams and groundwater quality.

The plant's treated effluent was discharged into local tributaries of the Danube River system, which flows through Central and Eastern Europe before reaching the Black Sea. The receiving waters support diverse aquatic life and are part of a sensitive watershed where nutrient management is critical to prevent eutrophication. The region's agricultural activity increases the importance of effective wastewater treatment to maintain water quality.
