Beauvezer Wastewater Treatment Plant | Advanced Treatment in Provence-Alpes-Côte d'Azur

The Beauvezer wastewater treatment plant is located in the commune of Beauvezer, within the Alpes-de-Haute-Provence department of the Provence-Alpes-Côte d'Azur region in southeastern France. The plant serves a population equivalent of 3,220 and has a designed capacity of 6,500 cubic meters per day, with an average daily discharge volume of 574.44 cubic meters. As an advanced treatment facility, the Beauvezer plant goes beyond the secondary treatment requirements mandated by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive requires secondary treatment for populations between 2,000 and 10,000, but the plant's advanced level indicates additional nutrient removal or polishing steps, likely to protect sensitive receiving waters in the Alpine region. The plant discharges treated effluent into the local watershed, which ultimately drains into the Verdon River, a major tributary of the Durance River. The Durance flows into the Rhône River, which empties into the Mediterranean Sea. The Verdon River is known for its turquoise waters and supports diverse aquatic life, including several fish species. The advanced treatment helps maintain water quality in this ecologically sensitive Alpine river system.

The Beauvezer plant discharges into the Verdon River basin, a tributary of the Durance River, which flows into the Rhône River and ultimately the Mediterranean Sea. The Verdon River is a pristine Alpine watercourse known for its clear waters and supports a variety of aquatic species, including the endangered European eel and native trout. The advanced treatment level helps protect the river's ecological integrity, particularly during low-flow summer months when dilution capacity is reduced.
