BORDEAUX PIAN MEDOC 2 is a wastewater treatment plant located in Parempuyre, a commune in the Gironde department of Nouvelle-Aquitaine, southwestern France. The plant serves a population of around 15,080, placing it in the medium agglomeration category under EU regulations. It is situated near the Garonne River estuary, part of the larger Gironde estuary system. As a French plant serving a population between 10,000 and 150,000, BORDEAUX PIAN MEDOC 2 is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a moderate scale. The treated effluent from BORDEAUX PIAN MEDOC 2 is discharged into the local watershed, which ultimately drains into the Garonne River and then the Gironde estuary, a major tidal estuary on the Atlantic coast. This estuary supports diverse aquatic life, including migratory fish species such as salmon and eels. The plant's operation is crucial for protecting the water quality of this ecologically sensitive area.
Environmental context
The plant discharges into the Garonne River watershed, which flows into the Gironde estuary, the largest estuary in western Europe. This estuary is a critical habitat for migratory fish and supports a rich ecosystem. The surrounding region includes wetlands and marshes that provide flood control and water purification services. Protecting water quality in this area is essential for maintaining biodiversity and supporting local fisheries.
