Overview
St VINCENT DE TYROSSE 2 is a wastewater treatment plant serving Saint-Jean-de-Marsacq in Nouvelle-Aquitaine, France. It serves a population of 6,830 and has a designed capacity of 1.00 (units unspecified).
St VINCENT DE TYROSSE 2 is a wastewater treatment facility located in Saint-Jean-de-Marsacq, within the Landes department of Nouvelle-Aquitaine, France. The plant serves a population of approximately 6,830 people, placing it in the small-to-medium agglomeration category under French regulations. As a French plant serving fewer than 10,000 people, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries. The designed capacity is reported as 1.00, though the unit is unspecified; typical plants of this scale have capacities in the range of thousands of cubic meters per day. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Adour River basin and then into the Bay of Biscay (Atlantic Ocean). The receiving waters support diverse aquatic life and are important for regional biodiversity, including migratory fish species such as salmon and eels.
Environmental context
The plant discharges into the Adour River basin, which flows into the Bay of Biscay in the Atlantic Ocean. This watershed supports a variety of freshwater and estuarine habitats, including wetlands that are important for bird migration and fish spawning. The downstream environment is ecologically sensitive, with the Adour estuary providing nursery grounds for marine species.

The treated effluent is discharged into the local watershed, which flows into the Adour River basin and eventually reaches the Bay of Biscay in the Atlantic Ocean.
As a French plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries for agglomerations of this size.
For plants of this scale in France, secondary treatment (biological treatment) is standard, often with nutrient removal if discharging into sensitive areas. The EU directive mandates secondary treatment for all discharges from agglomerations above 2,000 population equivalent.
