Hohn GKA Wastewater Treatment Plant - Schönberg, Rheinland-Pfalz, Germany

Hohn GKA is a wastewater treatment plant located in Schönberg, within the municipality of Höhn in the Westerwaldkreis district of Rheinland-Pfalz, Germany. The plant serves a population of approximately 3,735 people and is part of the region's municipal wastewater infrastructure. The plant employs advanced treatment processes, which go beyond the secondary treatment standards required by the EU Urban Waste Water Treatment Directive (91/271/EEC). With a designed capacity of 4,700 m³/day and an average discharge volume of 898.14 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local waterways that ultimately drain into the Rhine River basin. The Westerwald region is characterized by its low mountain range and forested landscapes, and the plant plays a key role in protecting the local aquatic environment from nutrient pollution and other contaminants.

The plant discharges into small streams that feed into the Rhine River basin, which flows through Germany and the Netherlands into the North Sea. The Westerwald region is ecologically sensitive, supporting diverse aquatic life and serving as an important habitat for species such as the European brook lamprey. Advanced treatment helps reduce nutrient loads, protecting downstream water quality in the Rhine and the North Sea.
