Peyruis village 2 Wastewater Treatment Plant, Peyruis, France

Peyruis village 2 is a municipal wastewater treatment plant located in Peyruis, a commune in the Alpes-de-Haute-Provence department of Provence-Alpes-Côte d'Azur, France. The plant serves a population of 3,333 and is situated near the Autoroute du Val de Durance, reflecting its role in the region's wastewater infrastructure. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,500 m³/day and a current discharge volume of 594.60 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Durance River, a major tributary of the Rhône. The Durance River supports diverse aquatic life and is an important water source for irrigation and hydroelectric power in the region. The plant's secondary treatment helps protect the river's water quality.

The plant discharges into the Durance River basin, which flows into the Rhône River and eventually the Mediterranean Sea. The Durance is a dynamic river that supports a variety of fish species and riparian habitats. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain the ecological health of the river and downstream environments.
