Overview
AUBIGNAN Intercommunale is a municipal wastewater treatment plant serving Aubignan in Provence-Alpes-Côte d'Azur, France. It treats wastewater for approximately 38,000 people under the EU Urban Waste Water Treatment Directive.
AUBIGNAN Intercommunale is a municipal wastewater treatment plant located in Aubignan, a commune in the Vaucluse department of Provence-Alpes-Côte d'Azur, southeastern France. The plant serves a population of around 38,000, placing it in the medium agglomeration category under European Union regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide at least secondary treatment, with more stringent tertiary treatment if the receiving waters are designated as sensitive areas. The directive sets clear standards for effluent quality. The treated wastewater is discharged into the local watershed, which ultimately drains into the Rhône River basin. The Rhône flows into the Mediterranean Sea, supporting diverse aquatic ecosystems and important migratory corridors for fish species. The plant plays a key role in protecting water quality in this region.
Environmental context
The plant discharges into the local water system that feeds into the Ouvèze River, a tributary of the Rhône. The Rhône River flows into the Mediterranean Sea, supporting a rich delta ecosystem and important fisheries. The region's Mediterranean climate means seasonal variations in flow, requiring robust treatment to protect downstream aquatic life and coastal water quality.
