BRIARE Wastewater Treatment Plant, Briare, Centre-Val de Loire, France

The BRIARE wastewater treatment plant is located in Briare, a commune in the Loiret department of the Centre-Val de Loire region, France. The plant serves a population of approximately 4,860 and has a designed capacity of 8,000 m³/day, with an average discharge volume of 867.02 m³/day. It is an inland facility, situated away from coastal areas. 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. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. As a French facility, it operates under national regulations transposing the EU 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 Loire River, one of France's major rivers. The Loire basin supports diverse aquatic ecosystems and is an important corridor for migratory fish such as Atlantic salmon and European eel. The plant's advanced treatment helps maintain water quality in this ecologically significant river system.

The BRIARE plant discharges into the Loire River basin, which flows through central France before reaching the Atlantic Ocean. The Loire is a large, free-flowing river with diverse habitats supporting species like the European beaver and various waterfowl. The plant's advanced treatment reduces nutrient loads, helping to prevent eutrophication in downstream waters, including the Loire estuary and the Bay of Biscay.
