Overview
MOUILLERON LE CAPTIF La Micheliere is an advanced wastewater treatment plant in Mouilleron-le-Captif, Pays de la Loire, France. It serves approximately 3,913 people with a designed capacity of 3,600 m³/day.
MOUILLERON LE CAPTIF La Micheliere is a wastewater treatment plant located in the commune of Mouilleron-le-Captif, within the Vendée department of the Pays de la Loire region in western France. The facility serves a population of about 3,913 residents and has a designed capacity of 3,600 cubic meters per day, with an average discharge volume of 698.07 cubic meters per day. 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. As a French facility, it operates under national regulations transposing the directive, with oversight from the local water agency (Agence de l'Eau Loire-Bretagne). The treated effluent is discharged into local watercourses that drain into the Atlantic Ocean via the Vendée River and the Bay of Biscay. The plant plays a key role in protecting the region's aquatic ecosystems, including the Marais Poitevin wetlands, by reducing nutrient loads and preventing eutrophication in downstream coastal waters.
Environmental context
The plant discharges into the local hydrographic network that feeds the Vendée River, which flows into the Bay of Biscay on the Atlantic coast. This region includes ecologically sensitive areas such as the Marais Poitevin, a large wetland complex that supports diverse birdlife and aquatic species. Advanced treatment helps control nutrient pollution, safeguarding water quality in both freshwater and coastal environments.
