CAVAILLON Wastewater Treatment Plant, Cavaillon, Provence-Alpes-Côte d'Azur, France

The CAVAILLON wastewater treatment plant is located in Cavaillon, a commune in the Vaucluse department of the Provence-Alpes-Côte d'Azur region in southeastern France. The plant serves a population of approximately 48,000 people, classifying it as a medium-sized agglomeration under EU regulations. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size discharging into freshwater. The plant's operational status and permit information are not disclosed, but French wastewater facilities are typically regulated by the Agence de l'Eau and local authorities. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Durance River, a major tributary of the Rhône River. The Rhône flows into the Mediterranean Sea via the Camargue delta, a region of high ecological importance. The plant plays a key role in protecting the Durance and Rhône river systems from nutrient pollution, supporting aquatic biodiversity and downstream water quality.

The CAVAILLON plant discharges into the Durance River, a major tributary of the Rhône River. The Rhône flows through the Camargue delta into the Mediterranean Sea, an ecologically sensitive area supporting diverse aquatic life and migratory bird species. The plant's treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the river and coastal waters.
