Overview
SALAVAS wastewater treatment plant in Salavas, Auvergne-Rhône-Alpes, France, serves about 3,180 people with advanced treatment. It discharges 567.31 cubic meters per day into the local watershed.
The SALAVAS wastewater treatment plant is located in Salavas, a commune in the Ardèche department of the Auvergne-Rhône-Alpes region, France. The plant serves a population of approximately 3,180, placing it in the small agglomeration category under French regulations. The facility employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The plant has a designed capacity of 4,000 cubic meters per day and currently discharges an average volume of 567.31 cubic meters per day, indicating significant spare capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Ardèche River and then the Rhône River, a major European waterway flowing into the Mediterranean Sea. The plant's advanced treatment helps protect the sensitive karstic environment of the Ardèche region and supports downstream aquatic ecosystems.
Environmental context
The plant discharges into the Ardèche River basin, a tributary of the Rhône River. The Ardèche River flows through a limestone karst landscape, creating unique gorges and supporting diverse aquatic life. The Rhône River carries the effluent to the Mediterranean Sea, where nutrient inputs can affect coastal marine ecosystems. The advanced treatment at SALAVAS helps minimize nutrient loading and protects the ecological integrity of these downstream water bodies.
