The plant serves a population of approximately 8,119 people, placing it in the small-to-medium agglomeration category under EU regulations. As a German facility, KA Stolzenau operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes and capacity are designed to meet these standards, ensuring compliance with national and EU water quality requirements. The treated effluent from KA Stolzenau is discharged into the Weser River, a major waterway in northern Germany that flows through the states of Niedersachsen and Bremen before reaching the North Sea. The plant plays a key role in protecting the Weser's water quality and the downstream aquatic ecosystem.

KA Stolzenau discharges into the Weser River, which flows northward through Niedersachsen and Bremen, ultimately draining into the North Sea. The Weser supports diverse aquatic life and is an important migratory corridor for fish species. The plant's treatment helps maintain water quality in this ecologically significant river system.
