Overview
Saint-Agrève wastewater treatment plant in Auvergne-Rhône-Alpes, France, serves 3,510 people with advanced treatment. It discharges 626.18 m³/day and has a designed capacity of 7,500 m³/day.
The Saint-Agrève wastewater treatment plant is located in the commune of Saint-Agrève, within the Ardèche department of the Auvergne-Rhône-Alpes region in France. The facility serves a population of approximately 3,510 residents and operates with advanced treatment processes, ensuring high-quality effluent before discharge. As a French wastewater treatment plant serving a small agglomeration, it operates under the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. The plant's advanced treatment level exceeds these requirements, likely due to the sensitivity of the receiving environment. The facility has a designed capacity of 7,500 m³/day and currently treats an average daily volume of 626.18 m³, indicating significant reserve capacity. The treated effluent is discharged into a local watercourse that ultimately drains into the Rhône River basin. The Rhône is one of Europe's major rivers, flowing into the Mediterranean Sea. The advanced treatment helps protect downstream aquatic ecosystems and supports the ecological health of the Rhône watershed, which is important for biodiversity and water quality in the region.
Environmental context
The plant discharges into a tributary of the Eyrieux River, which flows into the Rhône River, a major European waterway that empties into the Mediterranean Sea. The Rhône basin supports diverse aquatic life and is an important migratory corridor for fish species. Advanced treatment at this plant helps reduce nutrient loading and protects downstream water quality in this ecologically sensitive watershed.
