The plant serves a population of approximately 84,750, classifying it as a large agglomeration under EU regulations. It is situated near the source of the Danube River, which originates in the Black Forest region. As a German plant serving over 50,000 people, SKA Donaueschingen is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum and tertiary treatment in sensitive areas. The plant's designed capacity is 1.00 (likely in million cubic meters per year or similar unit), indicating a significant treatment infrastructure. German plants of this scale typically employ advanced biological treatment with nutrient removal. The plant discharges treated wastewater into the local water system, which feeds into the Danube River. The Danube is one of Europe's most important rivers, flowing through multiple countries to the Black Sea. The plant's operations are critical for protecting the water quality of the Danube headwaters and downstream ecosystems, including the Danube Delta, a ecologically sensitive area.

SKA Donaueschingen is located in the headwaters of the Danube River, which originates in the Black Forest and flows eastward through Central and Eastern Europe to the Black Sea. The receiving water body is part of the Danube basin, a major European watershed supporting diverse aquatic life and migratory fish species. The plant's discharge contributes to the overall water quality of the Danube, which is subject to the EU Water Framework Directive. The region is characterized by a temperate climate and mixed urban-forest land use, with the Black Forest providing important groundwater recharge and biodiversity.
