The Basque Country Agglomeration in partnership with the municipalities concerned wishes to provide real-time information on bathing conditions to users by equipping themselves with a digital tool. This project is part of the continuity of the bathing water quality forecasting tools developed in the Innovation Partnership for Active Beach Management project co-financed by the ERDF 2014-2020. This tool aims to establish a relationship of trust between communities and users to guarantee the physical and health safety of bathers in the bathing areas of the Basque Country.
