    • ​Fight against erosion of the beach
    The system makes it possible to fight erosion of the beach without any negative impact on the fauna, flora and neighboring shores. it is invisible and silent and does not disfigure the landscape.
    Installed for 19 years on the beach of Sables d'Olonne, it allows an effective fight against the erosion and facilitates the resilience of the beach.
    • Filtered seawater production
    The drainage of the beach allows the production of a considerable amount of slowly and naturally filtered water which can be valorized for many uses such as:- Recreational sea water basin supply (case of La Baule project)- Aquaculture / shellfish farming / Aquarium (Nausicaa Aquarium case in Boulogne sur mer (62, 2017)- Desalination to produce drinking water (the high level of filtration makes it possible to get rid of the pretreatment stages) (prototype case of Saint Gilles Croix de Vie (85)
    • Thalassothermie
    The system provides filtered seawater with powerful heat pump devices that produce heat and cool with significant energy savings.
    It contributes to the reduction of greenhouse gas emissions in the atmosphere.
