FONTENOY Wastewater Treatment Plant, Fontenoy-sur-Moselle, Grand Est, France

The FONTENOY wastewater treatment plant is located in Fontenoy-sur-Moselle, in the Grand Est region of France. It serves a population of approximately 3,250 residents, operating as a municipal facility within the Meurthe-et-Moselle department. The plant is situated inland, away from coastal areas, and is part of the regional water management infrastructure. The plant employs advanced treatment processes, ensuring a high level of effluent quality. It has a designed capacity of 4,000 m³/day and currently discharges an average of 579.79 m³/day, indicating significant spare capacity. As a French facility, it operates under the national regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment for agglomerations of this size. The treated effluent is discharged into the local watershed, which ultimately drains into the Moselle River and then the Rhine River, flowing towards the North Sea. The plant plays a key role in protecting the Moselle River basin from pollution, supporting aquatic life and downstream water quality in this ecologically sensitive region.

The plant discharges into the Moselle River basin, a tributary of the Rhine River, which flows into the North Sea. This watershed supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The advanced treatment helps protect water quality in the Moselle and Rhine rivers, reducing nutrient and pollutant loads that could otherwise impact downstream habitats and drinking water sources.
