The Consorci d’Aigües Costa Brava Girona (CACBGi) is a public body created in 1971 as an initiative from the Diputació de Girona, the Confederación Hidrográfica del Pirineo Oriental, and twenty-seven coastal municipalities in the Alt Empordà, Baix Empordà and La Selva, to address tourism development and the lack of hydraulic infrastructure in the Girona region.
On January 1, 2021, twenty more municipalities along the Girona coastline were added, becoming the first expansion in its history. Currently, it manages, within the water cycle, the sanitation, water regeneration and primary water supply that serves more than a million people in the summer.
