LA VRAIE CROIX Wastewater Treatment Plant, La Vraie-Croix, Brittany

LA VRAIE CROIX is a wastewater treatment plant located in La Vraie-Croix, within the Morbihan department of Brittany, France. The facility serves a population equivalent of 14,616 and has a designed capacity of 1.00, placing it in the medium agglomeration category under EU classification. As a French plant, LA VRAIE CROIX operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater or estuaries. The plant's treatment process and operational status are consistent with the regulatory framework for medium-sized communities in Brittany. The plant's treated effluent is discharged into the local watershed, which drains into the Gulf of Morbihan, a semi-enclosed marine inlet connected to the Bay of Biscay and the Atlantic Ocean. The Gulf of Morbihan is an ecologically sensitive area supporting diverse aquatic life, including seagrass beds and migratory bird populations.

The plant discharges into the local watershed that flows into the Gulf of Morbihan, a coastal inlet in southern Brittany. The Gulf is a semi-enclosed marine environment with rich biodiversity, including seagrass meadows and important bird habitats. The receiving waters ultimately reach the Bay of Biscay and the Atlantic Ocean, making nutrient management critical to prevent eutrophication in this sensitive coastal ecosystem.
