Oberleichtersbach Wastewater Treatment Plant, Untergeiersnest, Bavaria

Oberleichtersbach wastewater treatment plant was located in Untergeiersnest, a locality in the municipality of Schondra, within the Bad Kissingen district of Bavaria, Germany. The plant served a small population of approximately 1,320 people before its closure. As a closed facility, it no longer treats wastewater for the community. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size (under 2,000 population equivalent) are typically required to provide appropriate treatment, often secondary treatment or equivalent. The plant's discharge would have been to a local watercourse, likely within the Schondra river system, which flows into the Sinn River, then into the Franconian Saale, and ultimately into the Main River and the Rhine basin. The region is characterized by forested hills and agricultural land, with the Schondra valley supporting local aquatic life. The closure of the plant may have led to connection to a larger nearby facility or alternative treatment solutions.

The plant's discharge would have entered the Schondra river, a tributary of the Sinn, which flows into the Franconian Saale and then the Main River, part of the Rhine basin. The Schondra valley supports diverse aquatic life, including fish species typical of central European streams. The area is not within 50 km of the coast, so no direct marine impact.
