ENVEITG2 Wastewater Treatment Plant, Comus, Occitanie, France

ENVEITG2 is an advanced wastewater treatment plant located in Comus, a commune in the Aude department of Occitanie, southern France. The plant serves a population of approximately 2,276 people and is situated in a rural, mountainous area near the Pyrenees. As an advanced treatment facility, ENVEITG2 goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant has a designed capacity of 5,800 m³/day and currently discharges 406 m³/day, indicating significant spare capacity. The treated effluent from ENVEITG2 is discharged into local watercourses that feed into the Hers-Vif river, a tributary of the Ariège, which eventually flows into the Garonne and the Atlantic Ocean. The plant plays a key role in protecting the water quality of these rivers and the downstream ecosystems.

ENVEITG2 discharges into local streams that drain into the Hers-Vif river, a tributary of the Ariège, which joins the Garonne before reaching the Atlantic Ocean. The surrounding region includes the Pyrenees foothills, an area with sensitive aquatic habitats supporting diverse species such as the European otter and migratory fish. Advanced treatment helps minimize nutrient loading and protects downstream water quality.
