BRANTOME Nouvelle step Wastewater Treatment Plant, Brantôme en Périgord, Nouvelle-Aquitaine

BRANTOME Nouvelle step is a municipal wastewater treatment facility located in Brantôme en Périgord, in the Nouvelle-Aquitaine region of southwestern France. The plant serves a population of approximately 2,280 residents, reflecting its role in a small agglomeration within the Dordogne department. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a design capacity of 4,100 m³/day and a reported discharge volume of 406.75 m³/day, the facility operates well within its capacity, ensuring effective treatment of wastewater from the local community. The treated effluent is discharged into the local watershed, which ultimately drains into the Dronne River, a tributary of the Isle River, and then into the Dordogne River before reaching the Atlantic Ocean. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the Dordogne basin, which supports diverse fish populations and is an important ecological corridor in the region.

The plant discharges into the Dronne River, a tributary of the Isle River, which flows into the Dordogne River and eventually reaches the Atlantic Ocean. The Dordogne basin is ecologically sensitive, supporting diverse aquatic life including migratory fish species. The advanced treatment level helps minimize nutrient and pollutant loads, protecting downstream water quality and habitats.
