Grupo Agbar, formerly Aigües de Barcelona, is a Spanish water utility company.

The history of the group dates back to 1867, when the "Compagnie des Eaux de Barcelone" was founded in Liège to supply water to towns near Barcelona, today neighbourhoods in the city, through the Dosrius aqueduct.

[2][3] The Agbar Group was established in 1975, covering economic sectors as diverse as drinking water supply, sanitation and construction.

Subsequently, its activities were expanded to the fields of healthcare, technical vehicle inspection and tax collection.

[6] At the start of 2022, the Veolia Group, active in water and waste management and energy services, launched a takeover bid for Suez, taking control of 86.22% of its shareholding, a percentage that would be increased to 95.95% after the closing of its complementary offer to acquire the shares that had not participated in its initial takeover bid.
