Key project data:

  • 4.5 million m3 of wastewater are treated each year by the Les Sables d'Olonne wastewater treatment plant, equivalent to the volume of water in one of the 13 Vendée dams.
  • 150 m3/h will be treated by the refining plant during the experimental phase (from 2023 to 2026), i.e. a quarter of the discharges from the urban area. Then the entire 600m3/h (from 2027), i.e. a potential additional resource of 1.5 million m3 of drinking water over the period from May to October during dry years.
  • Technologies used in the refining plant: ultrafiltration and low-pressure reverse osmosis (Barrel Plug and Play, designed by Veolia, containing 200 membrane elements), ultraviolet disinfection and chlorination.
  • Overall budget for the Jourdain programme: 19.5 million euros over 10 years.
