Rabenau _ Londorf Wastewater Treatment Plant, Londorf, Hessen, Germany

The Rabenau _ Londorf wastewater treatment plant is located in Londorf, a town in the Landkreis Gießen district of Hessen, Germany. The facility serves a population of approximately 6,291 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). As a German plant serving fewer than 10,000 population equivalents, it is subject to national regulations implementing the EU directive, which typically require secondary treatment or equivalent. The plant's operational details and specific treatment processes are managed by local municipal authorities, ensuring compliance with German water quality standards. The treated effluent from the plant is discharged into local watercourses that drain into the Lahn River, a tributary of the Rhine. The Rhine basin supports diverse aquatic ecosystems and is a major European waterway. The plant plays a key role in protecting the local watershed from nutrient pollution and maintaining water quality for downstream communities and habitats.

The plant discharges into small streams that flow into the Lahn River, which joins the Rhine near Koblenz. The Rhine is a major European river supporting diverse fish populations and migratory species. The surrounding region is characterized by agricultural land and small settlements, making nutrient removal important to prevent eutrophication in downstream waters.
