Kaub Wastewater Treatment Plant, Kaub, Rhineland-Palatinate, Germany

Kaub wastewater treatment plant is located in the town of Kaub, in the Rhein-Lahn-Kreis district of Rhineland-Palatinate, Germany. The plant served a population of approximately 1,500 people and was designed with a capacity of 4,000 cubic meters per day. It is now closed. The plant provided advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal to protect sensitive water bodies. The plant's discharge likely entered the Rhine River, which flows through the Rhine Gorge, a region of ecological importance. The Rhine ultimately drains into the North Sea, supporting diverse aquatic life and serving as a major migratory corridor for fish.

The plant is situated near the Rhine River, a major European waterway that flows through the Rhine Gorge before reaching the North Sea. The Rhine supports diverse aquatic ecosystems and is an important migratory corridor for fish species such as salmon and eel. The advanced treatment level would have helped protect water quality in this ecologically sensitive region.
