Overview
CUXAC D AUDE is an advanced wastewater treatment plant in Cuxac-d'Aude, Occitanie, France, serving approximately 5,334 people with a designed capacity of 6,000 m³/day and a discharge volume of 951.58 m³/day.
CUXAC D AUDE is a municipal wastewater treatment plant located in Cuxac-d'Aude, a commune in the Aude department of Occitanie, southern France. The plant serves a population of about 5,334 residents and is designed to handle up to 6,000 cubic meters of wastewater per day, with an average daily discharge of 951.58 cubic meters. The plant employs advanced treatment processes, going beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. As a facility in France, it operates under national regulations transposing the directive, with oversight from the local water agency (Agence de l'Eau). The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea via the Aude River and its coastal lagoons. The region's aquatic ecosystems, including the nearby Narbonne lagoon complex, benefit from the advanced treatment that reduces nutrient loading and helps prevent eutrophication in these sensitive coastal environments.
Environmental context
The plant discharges into the Aude River basin, which flows into the Mediterranean Sea near Narbonne. The downstream environment includes coastal lagoons such as the Étang de Bages-Sigean, which are ecologically sensitive areas supporting diverse aquatic life and migratory birds. Advanced treatment at this plant helps minimize nutrient pollution, protecting these fragile ecosystems from eutrophication and maintaining water quality for both wildlife and human use.
