LE BIGNON 1 Le Pre Peau Wastewater Treatment Plant, Le Bignon, France

LE BIGNON 1 Le Pre Peau is a wastewater treatment facility located in Le Bignon, a commune in the Loire-Atlantique department of Pays de la Loire, France. The plant serves a population of around 2,100 residents, classifying it as a small agglomeration under French and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,000 cubic meters per day and a current discharge volume of 374.64 cubic meters per day, the facility operates well within its capacity, ensuring effective treatment of local wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River and then the Atlantic Ocean. The plant plays a key role in protecting the region's water quality, particularly in the context of the Loire-Atlantique area, which supports diverse aquatic life and agricultural activities.

The plant discharges into the local watershed that feeds the Loire River, one of France's major rivers, which flows into the Bay of Biscay in the Atlantic Ocean. This region supports diverse aquatic ecosystems, including migratory fish species such as Atlantic salmon and European eel. The advanced treatment helps minimize nutrient and pollutant loads, protecting downstream water quality and ecological health.
