The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Aulne River and the Rade de Brest. The plant's proximity to the coast (within 10 km) means that its advanced treatment level helps protect sensitive marine and estuarine ecosystems from nutrient pollution and other contaminants.
Environmental context
The plant discharges into the Aulne River basin, which flows into the Rade de Brest, a large coastal estuary in Brittany. This area supports diverse aquatic life, including migratory fish species and extensive seagrass beds. The advanced treatment level helps minimize nutrient loading and protects the ecological balance of the downstream marine environment.
