Herborn _ Guntersdorf Wastewater Treatment Plant, Gunterdsdorf, Hessen, Germany

The Herborn _ Guntersdorf wastewater treatment plant is located in Gunterdsdorf, a locality within the town of Herborn in the Lahn-Dill-Kreis district of Hessen, Germany. The plant serves a population of about 10,000 people, placing it in the category of a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). As a German facility, the plant operates under the EU UWWTD (91/271/EEC), which requires secondary treatment for agglomerations of this size. Germany implements this directive through national legislation, ensuring that wastewater is treated to protect water quality. The plant's treatment process and capacity are consistent with standards for communities of this scale. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Lahn River, a tributary of the Rhine. The Rhine basin is a major European watershed supporting diverse aquatic ecosystems. The plant plays a key role in maintaining water quality in this region, protecting downstream habitats and drinking water sources.

The plant discharges into the Lahn River system, which flows into the Rhine River and ultimately the North Sea. The Lahn-Dill region features a mix of forested hills and agricultural land, with the river supporting fish species such as trout and grayling. The treatment plant helps reduce nutrient loads and pollutants, safeguarding the ecological health of the Lahn and Rhine basins.
