Overview
JALLAIS nouvelle is an advanced wastewater treatment plant in Beaupréau-en-Mauges, Pays de la Loire, France, serving 2,400 people with a designed capacity of 3,100 m³/day.
JALLAIS nouvelle is an advanced wastewater treatment plant located in Beaupréau-en-Mauges, within the Pays de la Loire region of France. The facility serves a population of approximately 2,400 residents and has a designed capacity of 3,100 m³/day, with an average discharge volume of 428.16 m³/day. As an advanced treatment plant, JALLAIS nouvelle goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent French and European standards. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size are required to provide secondary treatment, but the advanced level here indicates additional nutrient removal, likely due to the sensitivity of the receiving environment. The plant discharges treated wastewater into local watercourses that drain into the Loire River basin, ultimately reaching the Atlantic Ocean. The Pays de la Loire region is known for its agricultural landscapes and river ecosystems, where nutrient pollution from wastewater can impact water quality. Advanced treatment helps protect downstream aquatic habitats and supports biodiversity in the region.
Environmental context
The treated effluent from JALLAIS nouvelle enters local streams that flow into the Loire River, one of France's major rivers, which empties into the Bay of Biscay in the Atlantic Ocean. The Loire basin supports diverse aquatic life and is an important ecological corridor for migratory fish species. Advanced treatment reduces nutrient loads, helping to prevent eutrophication in downstream waters and maintain the ecological balance of the river and coastal zone.
