Overview
SAINT MARTIN LACAUSSADE wastewater treatment plant in Saint-Martin-Lacaussade, Nouvelle-Aquitaine, France, serves 2,209 people with advanced treatment and a designed capacity of 2,700 m³/day.
The SAINT MARTIN LACAUSSADE wastewater treatment plant is located in Saint-Martin-Lacaussade, within the Nouvelle-Aquitaine region of southwestern France. The facility serves a population of approximately 2,209 and is situated near the Gironde estuary, a major coastal environment. As a small agglomeration, the plant plays a key role in managing local wastewater from the commune and surrounding areas. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 2,700 m³/day and an actual discharge volume of 394.08 m³/day, the facility operates well below its capacity, indicating room for future growth. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), French plants of this scale are required to meet secondary treatment standards, but this facility goes beyond with advanced treatment, reflecting a commitment to environmental protection. The treated effluent is discharged into the Gironde estuary, which flows into the Atlantic Ocean. The estuary is an ecologically sensitive area supporting diverse aquatic life, including migratory fish species. The plant's advanced treatment helps minimize nutrient and pollutant loads, protecting the estuary's water quality and downstream marine ecosystems.
Environmental context
The plant discharges into the Gironde estuary, a major tidal estuary on the Atlantic coast of France. This estuary is a critical habitat for migratory fish such as Atlantic salmon and European eel, and supports extensive bird populations. The advanced treatment reduces the risk of eutrophication and maintains the ecological balance of the downstream marine environment.
