SAINT JEAN DE BOISEAU Route du Pellerin Wastewater Treatment Plant, Saint-Jean-de-Boiseau, France

The SAINT JEAN DE BOISEAU Route du Pellerin wastewater treatment plant is located in Saint-Jean-de-Boiseau, a commune in the Loire-Atlantique department of Pays de la Loire, France. The plant serves a population of 4,800 and has a designed capacity of 4,000 m³/day, with an average discharge volume of 856.31 m³/day. The plant employs advanced treatment processes, exceeding the secondary treatment requirements of 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. The plant discharges into the local watershed, which ultimately drains into the Loire River and then the Bay of Biscay. The Loire estuary is a major ecological corridor supporting diverse aquatic life and migratory fish species. The plant's advanced treatment helps maintain water quality in this sensitive downstream environment.

The plant discharges into the local watershed that feeds the Loire River, one of France's longest rivers, which flows into the Bay of Biscay. The Loire estuary is an ecologically significant area supporting diverse aquatic life, including migratory fish such as Atlantic salmon and European eel. Advanced treatment at this plant helps reduce nutrient loading, protecting the estuary from eutrophication and preserving its ecological balance.
