FLAVIAC ROMPON Wastewater Treatment Plant, Le Pouzin, Auvergne-Rhône-Alpes

FLAVIAC ROMPON is a wastewater treatment plant located in Le Pouzin, within the Ardèche department of the Auvergne-Rhône-Alpes region in France. The plant serves a population of 2,290 and is part of the municipal infrastructure for the local community. The plant provides secondary treatment, which is the standard biological treatment stage that removes organic matter and suspended solids. With a designed capacity of 2,800 m³/day and an average discharge volume of 408.53 m³/day, the plant operates well within its capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to have secondary treatment, which FLAVIAC ROMPON meets. The treated effluent is discharged into a local watercourse that ultimately drains into the Rhône River, a major European river flowing into the Mediterranean Sea. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems from pollution.

The plant discharges into a tributary of the Rhône River, which flows south through the Rhône Valley and into the Mediterranean Sea. The Rhône basin supports diverse aquatic life and is an important migratory corridor for fish. The secondary treatment provided helps reduce nutrient loads and organic pollution, safeguarding water quality in the downstream river and coastal zone.
