SAINT JEAN D ILLAC CHAMBRERE Wastewater Treatment Plant, Saint-Jean-d'Illac, France

The SAINT JEAN D ILLAC CHAMBRERE wastewater treatment plant is located in Saint-Jean-d'Illac, a commune in the Gironde department of Nouvelle-Aquitaine, southwestern France. The plant serves a population of approximately 9,380 residents and has a designed capacity of 1.00, indicating it is a small to medium-scale facility. As a French wastewater treatment plant, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection, treatment, and discharge of urban wastewater. For agglomerations with a population equivalent between 2,000 and 10,000, secondary treatment is typically required, though more stringent treatment may be needed in sensitive areas. The plant's treated effluent is likely discharged into local watercourses that drain into the Garonne River basin, eventually reaching the Atlantic Ocean via the Gironde estuary. The facility plays a key role in protecting the region's water quality and supporting the ecological health of downstream aquatic environments.

The plant is situated inland, more than 50 km from the coast, and its discharge likely enters local streams that feed into the Garonne River. The Garonne flows through Bordeaux and into the Gironde estuary, a major ecological corridor supporting diverse aquatic life, including migratory fish species. The estuary is a dynamic environment influenced by tides and freshwater inflow, making nutrient management critical to prevent eutrophication and maintain water quality.
