The plant serves a population equivalent of approximately 38,865, classifying it as a medium-sized agglomeration under European Union regulations. As a German facility, AV Selbitztal operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary biological treatment for agglomerations with a population equivalent above 2,000. For sensitive areas, more stringent tertiary treatment may be mandated. The plant's specific treatment processes and capacity details are not publicly available, but the regulatory framework ensures compliance with national water quality standards. The treated effluent from AV Selbitztal is discharged into the local watershed, which ultimately drains into the Saale River and then into the Elbe River system, reaching the North Sea. The plant plays a key role in protecting the water quality of the Selbitz River and downstream ecosystems, supporting aquatic life and recreational uses in the region.

AV Selbitztal discharges into the Selbitz River, a tributary of the Saale, which flows into the Elbe and finally into the North Sea. The watershed supports diverse aquatic habitats and is important for regional biodiversity. The plant's operations help maintain water quality in this ecologically sensitive river system, which is subject to EU water framework directives.
