CAMBES ST CAPRAIS Wastewater Treatment Plant, Cambes, Nouvelle-Aquitaine

CAMBES ST CAPRAIS is a wastewater treatment plant located in Cambes, within the Gironde department of Nouvelle-Aquitaine, France. The facility serves a population of approximately 3,970 and is designed to handle up to 7,000 m³ of wastewater per day, with a current discharge volume of 708.24 m³/day. As a secondary treatment plant, it meets the standard requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000 in freshwater areas, ensuring effective removal of organic matter and suspended solids. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Garonne River and then the Gironde estuary, a major ecological corridor in southwestern France. The estuary supports diverse aquatic life and is an important migratory route for fish species such as salmon and eels.

The plant discharges into the Garonne River basin, which flows into the Gironde estuary, the largest estuary in Europe. This estuary is ecologically sensitive, supporting diverse aquatic habitats and serving as a critical migratory corridor for fish. The secondary treatment provided helps protect water quality in this downstream environment.
