MONTGUYON INTERCOMMUNALE Wastewater Treatment Plant, Saint-Martin-d'Ary, Nouvelle-Aquitaine

MONTGUYON INTERCOMMUNALE is an advanced wastewater treatment plant located in Saint-Martin-d'Ary, within the Charente-Maritime department of Nouvelle-Aquitaine, France. The plant serves a population of 5,492 and is part of the municipal wastewater infrastructure for the surrounding communities. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. With a designed capacity of 8,800 cubic meters per day and an actual discharge volume of approximately 980 cubic meters per day, the facility operates well within its capacity, providing reliable treatment for the local population. The treated effluent is discharged into local water bodies that ultimately drain into the Atlantic Ocean via the Gironde estuary. The plant plays a crucial role in protecting the region's aquatic ecosystems and supporting the ecological health of downstream environments, including sensitive coastal areas.

The plant discharges into local streams that flow into the Gironde estuary, a major tidal estuary on the Atlantic coast of France. This estuary supports diverse aquatic life, including migratory fish species, and is an important ecological corridor. The advanced treatment helps minimize nutrient loading and protects the water quality of the estuary and coastal zone.
