ELOYES Wastewater Treatment Plant, Éloyes, Grand Est, France

The ELOYES wastewater treatment plant is located in the commune of Éloyes, in the Vosges department of the Grand Est region of France. The plant serves a population of approximately 5,690 residents, placing it in the small agglomeration category under French and EU regulations. As a French wastewater facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates appropriate treatment before discharge into freshwater bodies to protect water quality and aquatic ecosystems. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Moselle River basin. The Moselle flows through the Vosges region and eventually joins the Rhine River, contributing to the broader Rhine-Maas basin. This waterway supports diverse aquatic life and is an important ecological corridor in northeastern France.

The plant discharges into the Moselle River basin, which flows through the Vosges region and joins the Rhine River. The Moselle supports diverse aquatic species and is a key migratory route for fish. The watershed is ecologically sensitive, with forests and wetlands that help maintain water quality. Downstream, the Rhine is a major European waterway, and the plant's treatment helps protect this transboundary river system.
