SAINT JULIEN BEYCHEVELLE Wastewater Treatment Plant, Beychevelle, Nouvelle-Aquitaine

SAINT JULIEN BEYCHEVELLE is a wastewater treatment plant located in Beychevelle, within the commune of Saint-Julien-Beychevelle in the Gironde department of Nouvelle-Aquitaine, France. The plant serves a population of approximately 7,018 people, placing it in the small agglomeration category under French and EU regulations. As a facility in an EU member state, the plant is subject to the Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries from agglomerations of this size. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or population equivalent), indicating a modest scale consistent with the served population. The plant is situated near the Gironde estuary, a major tidal estuary that flows into the Atlantic Ocean. The Gironde is formed by the confluence of the Garonne and Dordogne rivers and supports diverse aquatic life, including migratory fish species. The plant's discharge contributes to the water quality management of this ecologically significant estuary.

The plant discharges into the Gironde estuary, which is formed by the Garonne and Dordogne rivers and flows into the Bay of Biscay, Atlantic Ocean. This estuary is a critical habitat for migratory fish such as Atlantic salmon and European eel, and supports extensive mudflats and salt marshes. The plant's treatment performance directly affects the estuary's water quality and the health of its downstream marine environment.
