Culligan Acqua di casa (filtered tap water)

Culligan is a globally recognized brand specializing in water treatment solutions, including the filtration of local tap water for hospitality and residential use. The product shown is filtered water served in a reusable 'Culligan' branded glass bottle, often used in restaurants as 'Acqua di casa'.

Originally founded in the United States in 1936 by Emmett Culligan, the brand has grown into a multinational leader in water purification. Because the water is filtered on-site using local infrastructure and Culligan's specialized equipment, the ultimate source depends on the local municipal supply, while the equipment and branding represent the American-origin company. The brand is currently owned by BDT Capital Partners and BC Partners.
