ST SULPICE ET CAMEYRAC Wastewater Treatment Plant, Saint-Sulpice-et-Cameyrac, Nouvelle-Aquitaine

The ST SULPICE ET CAMEYRAC wastewater treatment plant is located in Saint-Sulpice-et-Cameyrac, a commune in the Gironde department of Nouvelle-Aquitaine, southwestern France. The plant serves a population of 3,741 and is part of the municipal infrastructure for the Bordeaux metropolitan area. It is situated near the Dordogne River, which flows into the Gironde estuary and ultimately the Atlantic Ocean. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,000 m³/day and an average discharge volume of 667.39 m³/day, the facility operates well below its capacity, indicating room for future growth. Advanced treatment typically includes nutrient removal to protect sensitive water bodies. The treated effluent is discharged into the local watershed, which drains into the Dordogne River. The Dordogne is a major river in southwestern France, known for its diverse aquatic ecosystems and as a key tributary to the Gironde estuary. The estuary is a critical habitat for migratory fish species such as salmon and sturgeon. The plant's advanced treatment helps minimize nutrient and pollutant loads, supporting the ecological health of these downstream environments.

The plant discharges into the Dordogne River basin, which flows into the Gironde estuary and then the Atlantic Ocean. The Dordogne is ecologically significant, supporting diverse aquatic life including migratory fish. The estuary is a vital nursery for marine species. Advanced treatment at the plant reduces nutrient inputs, helping to prevent eutrophication in these sensitive coastal waters.
