Overview
LEGE Le Pas Chataignier is an advanced wastewater treatment plant in Legé, Pays de la Loire, France, serving about 2,000 people with a design capacity of 3,000 m³/day.
LEGE Le Pas Chataignier is a wastewater treatment plant located in Legé, within the Pays de la Loire region of France. The facility serves a population of approximately 2,017 and has a design capacity of 3,000 cubic meters per day, with an average discharge volume of 359.83 m³/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 to protect sensitive receiving waters, aligning with France's implementation of the directive for sensitive areas. The treated effluent is discharged into local watercourses that ultimately drain into the Atlantic Ocean via the Loire River basin. The plant's inland location, more than 10 km from the coast, reduces direct marine impact, but its discharge contributes to the overall water quality of the regional watershed.
Environmental context
The plant discharges into the local watershed, which is part of the Loire River basin, one of France's major river systems. The Loire flows into the Atlantic Ocean, supporting diverse aquatic ecosystems and important migratory fish species. The advanced treatment helps protect downstream water quality in this ecologically sensitive region.
