The CAPB brings together 158 municipalities and exercises the GEMAPI competence by right. As such, it has decided to equip itself with a flood pre-alert system intended to assist it, in real time in the implementation of the actions enabling them to cope with a harmful hydrometeorological event. This assistance covers the phases of vigilance, the triggering of safeguard actions, until the end of the crisis, by means of information transmitted via multiple communication channels. This innovative expertise will reduce the vulnerability of the territory and its inhabitants to hydrometeorological risks. It will affect nearly 200000 inhabitants potentially exposed in the Basque Country.
