Overview
FORCALQUIER OUEST is an advanced wastewater treatment plant in Forcalquier, Provence-Alpes-Côte d'Azur, France. It serves approximately 3,098 people with a designed capacity of 4,000 m³/day.
FORCALQUIER OUEST is an advanced wastewater treatment plant located in Forcalquier, in the Alpes-de-Haute-Provence department of Provence-Alpes-Côte d'Azur, France. The plant serves a population of about 3,098, reflecting its role in a small agglomeration within the region. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. With a designed capacity of 4,000 m³/day and a discharge volume of 552.68 m³/day, the plant operates well within its capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), such small agglomerations are required to provide appropriate treatment, and advanced treatment aligns with sensitive area requirements. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Durance River, a major tributary of the Rhône River. The Rhône flows into the Mediterranean Sea, making the plant's performance important for downstream water quality and the ecological health of the Rhône delta and coastal zone.
Environmental context
The plant discharges into the Durance River basin, which feeds into the Rhône River, one of Europe's major rivers flowing into the Mediterranean Sea. The downstream environment includes ecologically sensitive areas such as the Camargue delta, a critical habitat for migratory birds and diverse aquatic life. Advanced treatment helps protect these ecosystems from nutrient pollution and other contaminants.
