Vendée Eau, with the help of Veolia, is preparing for the future through its Jourdain programme, the first experiment in France and Europe in wastewater treatment, to secure[...]
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.
