AZV Ermstal Metzingen is a municipal wastewater treatment plant located in Metzingen, Baden-Württemberg, Germany. It serves a population of approximately 70,600, classifying it as a medium-to-large agglomeration under EU regulations. The plant is part of the Abwasserverband Ermstal, a wastewater association managing treatment in the Ermstal region. As a German plant serving over 50,000 people, AZV Ermstal Metzingen is subject to the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment as a minimum. For agglomerations of this size, the directive also mandates more stringent treatment if the receiving waters are sensitive to eutrophication. The plant's treatment processes are designed to meet these regulatory standards, ensuring compliance with German water quality laws. The treated effluent from AZV Ermstal Metzingen is discharged into the Erms River, a tributary of the Neckar River, which flows into the Rhine River and ultimately the North Sea. The plant plays a crucial role in protecting the water quality of the Erms and downstream ecosystems, supporting aquatic life and recreational use of the river.
