Weimar _ Roth Wastewater Treatment Plant, Roth, Hessen, Germany

Weimar _ Roth is a former wastewater treatment plant located in the village of Roth, part of the municipality of Weimar (Lahn) in Hessen, Germany. The plant served a small population of 1,830 residents before its closure. As a closed facility, it no longer processes wastewater, and its infrastructure has been decommissioned. During its operation, the plant would have been subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's closure may reflect upgrades to regional wastewater infrastructure, with flows likely redirected to a larger facility in the area. The plant's receiving water body was likely a small tributary of the Lahn River, which flows into the Rhine and ultimately the North Sea. The region is characterized by rolling hills and agricultural land, with the Lahn River supporting diverse aquatic life and serving as an important corridor for fish migration.

The plant's discharge would have entered a local stream feeding the Lahn River, a tributary of the Rhine. The Lahn River supports diverse aquatic life and is an important migratory corridor for fish. The Rhine basin is ecologically sensitive, with efforts to improve water quality under the EU Water Framework Directive.
