Heidenrod _ Kemel Wastewater Treatment Plant, Kemel, Hessen, Germany

Heidenrod _ Kemel is an advanced wastewater treatment plant located in the village of Kemel, part of the municipality of Heidenrod in the Rheingau-Taunus-Kreis district of Hessen, Germany. The plant serves a population of approximately 2,700 residents, reflecting its role as a small-scale municipal facility in a rural setting. As an advanced treatment plant, it goes beyond the secondary treatment requirements mandated by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant's designed capacity of 2,700 m³/day matches the population served, indicating a well-sized infrastructure. The actual discharge volume of 389.11 m³/day suggests efficient operation with spare capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Rhine River basin. The Rhine is a major European waterway flowing through Germany into the North Sea. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the Rhine watershed, including fish spawning grounds and migratory corridors.

The plant discharges into small streams in the Wisper valley, which flow into the Rhine River near Lorch. The Rhine is a major European river that drains into the North Sea, supporting diverse aquatic life and serving as a critical migratory route for fish such as salmon and eel. Advanced treatment at this plant helps reduce nutrient loads, protecting downstream water quality in the Rhine basin.
