Leutenthal Wastewater Treatment Plant, Thüringen, Germany

Leutenthal wastewater treatment plant is located in the small town of Leutenthal, part of Ilmtal-Weinstraße in the Weimarer Land district of Thüringen, Germany. The plant served a population of approximately 1,783 people before its closure, reflecting its role in a rural community. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity was 2,480 m³/day, and the actual discharge volume was 388.30 m³/day, indicating a low utilization rate typical of small rural facilities. The treated effluent from the plant was discharged into local water bodies within the Saale river basin, which ultimately drains into the Elbe River and then the North Sea. The plant's closure means that wastewater from Leutenthal is now likely handled by a neighboring facility or alternative system, ensuring continued environmental protection.

The plant's discharge contributed to the Saale river basin, a tributary of the Elbe River, which flows into the North Sea. The local watershed supports diverse aquatic life and is part of a region with agricultural and natural landscapes. The closure of the plant may reduce local nutrient loads, benefiting downstream water quality.
