SAINT AUBIN D AUBIGNE Wastewater Treatment Plant, Saint-Aubin-d'Aubigné, Bretagne

SAINT AUBIN D AUBIGNE is an advanced wastewater treatment plant located in Saint-Aubin-d'Aubigné, a commune in the Ille-et-Vilaine department of Bretagne, France. The plant serves a population of approximately 4,800 residents and is part of the municipal wastewater infrastructure for the area. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 3,333 m³/day and a current discharge volume of 856.31 m³/day, the facility operates well within its capacity. As a French plant, it operates under the national regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The treated effluent is discharged into local watercourses that ultimately drain into the Atlantic Ocean via the Rance River basin. The plant plays a key role in protecting the water quality of the region's rivers and the downstream marine environment, supporting aquatic life and recreational uses.

The plant discharges into the local watershed of the Ille-et-Vilaine department, which is part of the larger Rance River basin flowing into the English Channel. The receiving waters support diverse aquatic ecosystems and are important for regional biodiversity. The advanced treatment helps minimize nutrient loading, protecting downstream estuarine and coastal habitats from eutrophication.
