Overview
Gréoux-les-Bains wastewater treatment plant serves 7,700 people 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.
The Gréoux-les-Bains wastewater treatment plant is located in the commune of Gréoux-les-Bains in the Alpes-de-Haute-Provence department of Provence-Alpes-Côte d'Azur, France. It serves a population of approximately 7,700 residents, classifying it as a small to medium agglomeration under EU regulations. As a French wastewater facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 10,000. The directive also mandates more stringent treatment if the discharge enters sensitive areas, such as nutrient-sensitive water bodies. The treated effluent is discharged into the local watershed, which ultimately drains into the Durance River, a major tributary of the Rhône. The Rhône flows into the Mediterranean Sea. The plant plays a key role in protecting the water quality of the Durance and downstream ecosystems, including the Camargue delta, a region of high ecological value.
Environmental context
The plant discharges into the Durance River basin, which flows into the Rhône River and then the Mediterranean Sea. The Durance supports diverse aquatic life and is an important water source for irrigation and drinking water. Downstream, the Rhône delta (Camargue) is a critical wetland for migratory birds and biodiversity. The plant's treatment helps reduce nutrient and pollutant loads entering this sensitive ecosystem.
