The Vaison la Romaine wastewater treatment plant is located in Vaison-la-Romaine, a commune in the Vaucluse department of Provence-Alpes-Côte d'Azur, southeastern France. The plant serves a population of approximately 43,000, classifying it as a medium 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 between 10,000 and 150,000 population equivalent. The directive also mandates more stringent treatment if the discharge enters sensitive areas, such as those subject to eutrophication. The regulatory framework ensures compliance with national and EU standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhône River via the Ouvèze River. The Rhône flows into the Mediterranean Sea, supporting diverse aquatic ecosystems along its course. The plant plays a key role in protecting the water quality of the Ouvèze and downstream environments from nutrient pollution and pathogens.
Environmental context
The plant discharges into the Ouvèze River, a tributary of the Rhône River, which flows into the Mediterranean Sea. The Rhône basin supports a variety of aquatic life, including migratory fish species. The region's Mediterranean climate means seasonal variations in flow, requiring careful management of nutrient loads to prevent eutrophication in downstream water bodies.
