Overview
La Bouexiere wastewater treatment plant in La Bouëxière, Bretagne, France, serves 1,650 people with advanced treatment. It discharges 294.36 m³/day and has a designed capacity of 3,100 m³/day.
La Bouexiere is a wastewater treatment plant located in La Bouëxière, a commune in the Ille-et-Vilaine department of Bretagne, France. The plant serves a population of approximately 1,650 people, classifying it as a small agglomeration under French and EU regulations. It is situated inland, away from coastal areas, and operates within the broader Rennes metropolitan region. The plant employs advanced treatment processes, which go beyond the secondary treatment standard 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 water bodies. The plant's designed capacity is 3,100 m³/day, and it currently treats an average daily flow of 294.36 m³, indicating ample reserve capacity for future growth. Treated effluent from La Bouexiere is discharged into local watercourses that eventually drain into the Vilaine River basin and ultimately the Atlantic Ocean. The plant plays a key role in protecting the region's water quality, particularly in the context of Bretagne's sensitive aquatic ecosystems, which are vulnerable to nutrient pollution from agricultural and urban sources.
Environmental context
La Bouexiere's treated effluent flows into local streams that are part of the Vilaine River basin, which drains into the Atlantic Ocean via the Vilaine estuary. The region's watershed supports diverse aquatic life and is ecologically sensitive to nutrient enrichment. Advanced treatment at the plant helps mitigate the risk of eutrophication in downstream water bodies, including coastal zones.
