The plant serves a population of approximately 2,005 people and is situated near the Gulf of Morbihan, a region known for its rich marine biodiversity.

Environmental context
The plant discharges into the Gulf of Morbihan, a semi-enclosed marine basin connected to the Atlantic Ocean. This area supports extensive seagrass beds, shellfish beds, and migratory bird populations. The coastal location requires careful management of nutrient and pathogen loads to prevent eutrophication and maintain water quality for recreational and ecological uses.
