Overview
Toulon sur Arroux wastewater treatment plant serves 1,179 people in Bourgogne-Franche-Comté, France. It provides advanced treatment with a designed capacity of 2,500 m³/day and discharges 210.33 m³/day.
The Toulon sur Arroux wastewater treatment plant is located in the commune of Toulon-sur-Arroux, within the Saône-et-Loire department of Bourgogne-Franche-Comté, France. This facility serves a population of 1,179 residents, representing a small agglomeration under French and EU classification. The plant employs advanced treatment processes, exceeding the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,500 m³/day and an average discharge volume of 210.33 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into the local watershed, which ultimately drains into the Arroux River, a tributary of the Loire River. The Loire basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and recreation. The plant's advanced treatment helps protect downstream water quality in this sensitive river system.
Environmental context
The plant discharges into the Arroux River, which flows into the Loire River, one of France's longest rivers, before reaching the Atlantic Ocean. The Loire basin is a critical habitat for migratory fish species such as Atlantic salmon and European eel. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters and supporting the ecological health of the Loire estuary.
