Valensole Wastewater Treatment Plant - Secondary Treatment for Valensole, France

The Valensole wastewater treatment plant is located in the commune of Valensole, within the Alpes-de-Haute-Provence department in the Provence-Alpes-Côte d'Azur region of southeastern France. The facility serves a population of approximately 3,000 residents and operates under the regulatory framework of the European Union's Urban Waste Water Treatment Directive (91/271/EEC). As a small agglomeration, it is required to provide appropriate treatment to protect the receiving environment. The plant provides secondary treatment, which is the standard level for inland communities of this size under EU regulations. The designed capacity of the plant is 2,250 cubic meters per day, and the current discharge volume is 535.19 cubic meters per day, indicating that the plant operates well below its maximum capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The 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. The plant plays a key role in protecting the water quality of the Durance River and its downstream ecosystems, which support diverse aquatic life and are important for regional water resources.

The Valensole plant discharges into the local watershed that feeds the Durance River, a major tributary of the Rhône River. The Rhône flows into the Mediterranean Sea, making the plant's operations important for the ecological health of the river system. The Durance River supports diverse aquatic habitats and is a key water source for agriculture and drinking water in the region. The plant's secondary treatment helps reduce nutrient and organic pollution, mitigating eutrophication risks in downstream water bodies.
