The SAINT JEAN DE MONTS Les 60 Bornes wastewater treatment plant is located in Saint-Hilaire-de-Riez, within the Vendée department of Pays de la Loire, France. The facility serves a population of approximately 22,917, classifying it as a medium-sized agglomeration under EU regulations.

Proper treatment is essential to protect these sensitive coastal ecosystems from nutrient pollution and pathogens.
Environmental context
The plant's treated effluent flows into the local river system, which drains into the Atlantic Ocean through the Bay of Biscay. The coastal waters of the Vendée region support important marine habitats, including seagrass beds and shellfish fisheries. Nutrient loading from wastewater can contribute to eutrophication in these nearshore environments, making effective treatment critical for maintaining water quality and ecological balance.
