The plant serves a population of 5,110 and has a designed capacity of 10,000 m³/day, with an average daily discharge of 911.61 m³/day. The plant employs advanced treatment processes, which go 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 is typically implemented in sensitive areas to reduce nutrient loads and protect receiving water bodies.

The area is ecologically sensitive, supporting diverse aquatic life and serving as an important habitat for migratory birds.
Environmental context
The plant's discharge enters the coastal watershed of the Aude department, flowing through the étangs (coastal lagoons) of the Narbonnaise region before reaching the Mediterranean Sea. These lagoons are ecologically sensitive, supporting diverse aquatic life and serving as important stopover points for migratory birds along the Mediterranean flyway. The advanced treatment helps minimize nutrient pollution, protecting the fragile lagoon ecosystem.
