Overview
CARCASSONNE nouvelle wastewater treatment plant serves the city of Carcassonne in Occitanie, France. It handles a population equivalent of 116,883 under the EU Urban Waste Water Treatment Directive.
CARCASSONNE nouvelle is a wastewater treatment plant located in Carcassonne, within the Occitanie region of southern France. The facility serves a population equivalent of 116,883, placing it in the large agglomeration category under EU regulations. Its address is near the Hippodrome de la Fajeolle, on Route de Montredon, in the Saint-Jacques de la Conte area. As a large agglomeration, the plant is expected to provide at least secondary treatment under the EU Urban Waste Water Treatment Directive (91/271/EEC). Given its population served, the plant likely operates with advanced treatment processes to meet stringent effluent standards, particularly if discharging into sensitive areas. The facility is part of France's national wastewater infrastructure, regulated by the French Ministry of Ecological Transition. The plant's treated effluent ultimately drains into the Aude River, which flows through Carcassonne and continues to the Mediterranean Sea. This water body supports diverse aquatic life and is important for regional ecology. The plant plays a key role in protecting the Aude River and downstream coastal waters from nutrient pollution and pathogens.
Environmental context
The plant discharges into the Aude River, which flows through Carcassonne and the surrounding Occitanie region before reaching the Mediterranean Sea near Narbonne. The Aude River supports a variety of fish species and provides habitat for migratory birds. Downstream, the coastal zone includes ecologically sensitive areas that benefit from reduced nutrient loads from properly treated wastewater.
