Overview
BRISCOUS SALINES 2 is an advanced wastewater treatment plant in Briscous, Nouvelle-Aquitaine, France, serving 1,435 people with a design capacity of 4,000 m³/day.
BRISCOUS SALINES 2 is an advanced wastewater treatment plant located in Briscous, within the Pyrénées-Atlantiques department of Nouvelle-Aquitaine, France. The facility serves a population of 1,435 and has a design capacity of 4,000 m³/day, with a current discharge volume of 256 m³/day. It is situated near the coast, reflecting the region's coastal and estuarine environment. As an advanced treatment plant, BRISCOUS SALINES 2 goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent French and EU standards. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment, but the advanced level here indicates a higher level of protection for sensitive receiving waters. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Bay of Biscay via the Adour River estuary. This coastal discharge area supports diverse marine life and is ecologically sensitive, making advanced treatment crucial for minimizing nutrient loading and protecting water quality in the bay.
Environmental context
The plant's treated effluent enters the local drainage network, which flows into the Adour River and then into the Bay of Biscay. This coastal zone supports diverse marine ecosystems, including fish nurseries and migratory bird habitats. Advanced treatment helps reduce nutrient inputs, protecting against eutrophication and maintaining water quality in the sensitive estuarine and coastal environment.

The plant serves a population of 1,435 people in the Briscous area.
The treated wastewater is discharged into the local watershed, which flows into the Adour River and ultimately into the Bay of Biscay.
The plant provides advanced treatment, which includes nutrient removal beyond secondary treatment. This is typical for sensitive coastal areas under the EU Urban Waste Water Treatment Directive.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 2,000 population equivalent. As an advanced treatment plant, it exceeds these requirements, likely due to its coastal location and the need to protect the Bay of Biscay.
