Perfectly integrated into the landscaped site, the ultra-compact water treatment plant of Guéthary, Saint-Jean de Luz and Acotz benefits from the most advanced technologies thus ensuring that its performance surpasses the required standards.
MSE, a Veolia Water Solutions & Technologies subsidiary, has created an exemplary "VIRUS FREE" treatment process comprised of biological treatment with membranes, a physical barrier and UV sterilization and disinfection. Treated effluents are released into the sea.
These processes protect the local environment from pollution - even with the plant's large variations in hydraulic and organic pollutants - and keep the sea accessible for fishermen, surfers and swimmers throughout the year.
