TOUCY Nouvelle Wastewater Treatment Plant, Toucy, Bourgogne-Franche-Comté

TOUCY Nouvelle is a municipal wastewater treatment plant located in Toucy, in the Bourgogne-Franche-Comté region of France. The plant serves a population of approximately 1,459 people and is part of the local sanitation infrastructure for this commune in the Yonne department. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,000 m³/day and an actual discharge volume of 260.28 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River basin. The receiving water body supports aquatic life and contributes to the ecological health of the region. The plant plays a key role in protecting local water quality and downstream environments.

The plant discharges into a tributary of the Loire River basin, which flows through central France before reaching the Atlantic Ocean. The local watershed supports diverse aquatic ecosystems, including fish populations and riparian habitats. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water quality in the Loire estuary and coastal zone.
