Wittlich ZKA Wengerohr Wastewater Treatment Plant, Altrich, Germany

Wittlich ZKA Wengerohr is a municipal wastewater treatment plant located in Altrich, within the Wittlich-Land district of Rheinland-Pfalz, Germany. The plant serves a population of approximately 36,340 people, placing it in the medium agglomeration category under German and EU regulations. As a German wastewater treatment facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes and capacity are designed to meet these regulatory standards. The plant discharges treated effluent into local watercourses that ultimately drain into the Moselle River, a major tributary of the Rhine. The Rhine basin supports diverse aquatic life and is an important ecological corridor in Europe. Proper treatment at this plant helps protect downstream water quality and the broader Rhine ecosystem.

The plant's treated effluent flows into the Lieser River, a tributary of the Moselle, which joins the Rhine River near Koblenz. The Rhine basin is a vital European waterway supporting diverse fish species and migratory birds. The Moselle region is known for its vineyards and sensitive aquatic habitats, making effective wastewater treatment essential for maintaining water quality and ecological balance.
