Overview
Gravenwiesbach Monstadt wastewater treatment plant serves Mönstadt, Hessen, Germany, treating wastewater for approximately 4,400 residents. The plant discharges into local waterways within the Lahn river basin.
The Gravenwiesbach Monstadt wastewater treatment plant is located in Mönstadt, a district of Grävenwiesbach in the Hochtaunuskreis district of Hessen, Germany. The plant serves a population of approximately 4,411 people, making it a small agglomeration under German and EU classification. As a German wastewater treatment plant serving fewer than 10,000 population equivalents, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC) and national German water law (Wasserhaushaltsgesetz). For small agglomerations, the directive requires appropriate treatment to meet receiving water quality objectives, typically secondary treatment or equivalent. The plant's treatment process ensures compliance with local discharge standards. The treated effluent is discharged into local streams that drain into the Lahn River, a tributary of the Rhine. The Rhine basin is a major European watershed supporting diverse aquatic ecosystems and providing drinking water for millions. The plant plays a key role in protecting water quality in this ecologically important region.
Environmental context
The plant discharges into small watercourses in the Lahn river basin, which flows into the Rhine River and ultimately the North Sea. The Lahn is a medium-sized river supporting fish species such as grayling and brown trout, and its floodplains provide habitat for migratory birds. The plant's treatment helps maintain water quality in this sensitive watershed, which is part of the larger Rhine ecosystem.
