The plant served a population of 1,950 and had a designed capacity of 3,150 cubic meters per day, with an average discharge volume of 844.59 cubic meters per day. The facility is now closed. As a German plant, it operated under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for small agglomerations. The plant provided advanced treatment, exceeding the minimum secondary treatment standard, which is typical for sensitive areas or to meet stringent effluent quality requirements. The plant's treated effluent likely discharged into a local watercourse within the Danube River basin, as Neu-Ulm lies near the Danube. The region's water bodies support diverse aquatic life and are part of a larger river system that flows into the Black Sea.

The plant is located in the Danube River basin, with the Danube flowing approximately 5 km south of Neu-Ulm. The Danube is a major European waterway that supports diverse aquatic ecosystems and provides habitat for fish species such as the Danube salmon. Downstream, the river flows through several countries before reaching the Black Sea, making water quality management critical for transboundary ecological health.
