Overview
Valreas chef lieu is a municipal wastewater treatment plant serving Valréas in Provence-Alpes-Côte d'Azur, France. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this size.
Valreas chef lieu is a municipal wastewater treatment plant located in Valréas, a commune in the Vaucluse department of Provence-Alpes-Côte d'Azur, southeastern France. The plant serves a population of approximately 13,000 people, placing it in the medium agglomeration category under EU classification. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes and capacity are managed to meet these regulatory standards. The treated effluent 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 along its course. The plant plays a key role in protecting downstream water quality and the ecological health of the region.
Environmental context
The plant discharges into the local watershed, part of the Rhône River basin. The Rhône flows southward through southeastern France and enters the Mediterranean Sea via the Camargue delta, a region of high ecological importance that supports diverse birdlife and aquatic species. The plant's operations help maintain water quality in this sensitive downstream environment.
