Overview
SAINT JEAN DE VERGES CHIVA is an advanced wastewater treatment plant in Saint-Jean-de-Verges, Occitanie, France, serving 3,256 people with a designed capacity of 4,000 m³/day.
SAINT JEAN DE VERGES CHIVA is a wastewater treatment facility located in Saint-Jean-de-Verges, a commune in the Ariège department of Occitanie, southern France. The plant serves a population of 3,256 and has a designed capacity of 4,000 m³ per day, with a current discharge volume of approximately 581 m³ per day. As an advanced treatment plant, it goes beyond the secondary treatment requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The advanced level indicates nutrient removal or other tertiary processes, ensuring high-quality effluent before discharge. The plant's treated water is discharged into the local watershed, which drains into the Ariège River and eventually the Garonne River, flowing toward the Atlantic Ocean. This contributes to the protection of downstream aquatic ecosystems and water quality in the region.
Environmental context
The plant discharges into the Ariège River basin, which flows northward to join the Garonne River near Toulouse. The Garonne then empties into the Gironde estuary and the Atlantic Ocean. The Ariège River supports diverse aquatic life, including fish species such as brown trout and European eel. Advanced treatment helps minimize nutrient loading and protects downstream water quality in this ecologically sensitive river system.
