Overview
LA TREMBLADE CDC wastewater treatment plant serves approximately 20,287 people in La Tremblade, Nouvelle-Aquitaine, France. It operates under the EU Urban Waste Water Treatment Directive, ensuring compliance with European standards.
LA TREMBLADE CDC is a municipal wastewater treatment plant located in La Tremblade, a commune in the Charente-Maritime department of Nouvelle-Aquitaine, southwestern France. The plant serves an estimated population of 20,287, placing it in the medium agglomeration category under EU classification. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The designed capacity is 1.00 (likely in thousands of cubic meters per day or population equivalent), indicating a facility scaled to handle the local load. The regulatory framework ensures appropriate standards. The plant discharges treated effluent into the local watershed, which drains into the Atlantic Ocean via the Seudre River estuary and the Pertuis d'Antioche. This coastal region supports diverse aquatic life and is ecologically sensitive due to its proximity to the Marennes-Oléron basin, a major oyster-producing area. The plant's performance is critical for protecting downstream marine ecosystems and maintaining water quality in the region.
Environmental context
The plant is located within 50 km of the Atlantic coast, in the Seudre River basin. Treated effluent likely flows into the Seudre River, which empties into the Pertuis d'Antioche, a marine strait between the Île d'Oléron and the mainland. This area is part of the Marennes-Oléron ecosystem, known for its oyster farming and diverse estuarine habitats. The plant's discharge must meet stringent standards to protect these sensitive coastal waters from nutrient pollution and pathogens.
