VALBERG Wastewater Treatment Plant, Péone, France

VALBERG is a wastewater treatment plant located in Péone, within the Alpes-Maritimes department of Provence-Alpes-Côte d'Azur, France. The plant serves a population of approximately 2,544 residents and is situated in the mountainous terrain of the French Alps, near the ski resort of Valberg. It is an inland facility, positioned well away from the coast. The plant employs advanced treatment processes, which go beyond the secondary treatment mandated by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 9,000 m³/day and an actual discharge volume of 453.85 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal demand. The advanced treatment likely includes nutrient removal to protect sensitive alpine water bodies. The treated effluent is discharged into the local watershed, which drains into the Var River system and eventually reaches the Mediterranean Sea. The plant's advanced treatment helps preserve the ecological quality of the mountain streams and the downstream river, supporting aquatic life and recreational uses in the region.

The plant discharges into the Var River basin, which flows through the Alpes-Maritimes and empties into the Mediterranean Sea near Nice. The upper Var watershed is ecologically sensitive, supporting diverse aquatic species and serving as a corridor for migratory fish. Advanced treatment at VALBERG helps minimize nutrient loading and protects the water quality of the river and the coastal marine environment.
