GRANGES SUR VOLOGNE Wastewater Treatment Plant, Granges-Aumontzey, France

GRANGES SUR VOLOGNE is an advanced wastewater treatment plant located in Granges-Aumontzey, in the Vosges department of Grand Est, France. It serves a population of 1,840 and has a designed capacity of 3,000 m³/day, with an actual discharge volume of 328.25 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a French facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size to protect sensitive water bodies. The treated effluent is discharged into the local watershed, which drains into the Vologne River, a tributary of the Moselle. The Moselle flows into the Rhine, eventually reaching the North Sea. The plant plays a key role in protecting the Vologne River and downstream aquatic ecosystems from nutrient pollution.

The plant discharges into the Vologne River, a tributary of the Moselle River, which flows into the Rhine and ultimately the North Sea. The Vosges region is known for its forested hills and sensitive freshwater ecosystems. Advanced treatment helps reduce nutrient loads, protecting downstream water quality and supporting diverse aquatic life in the Moselle and Rhine basins.
