The building was constructed without a single pipe running through the exterior walls to prevent corrosion and aesthetic damage.
The exterior tiles were produced by Royal Doulton, the same company that provided fine china for the British Royal Family.
The structure functioned as a water pressure tank until 1978, at which point it ceased its primary industrial duty.
The site covers an entire city block and is supported by a massive iron framework hidden behind the decorative facade.
The building was commissioned in response to the devastating yellow fever epidemics of the 1870s to ensure clean, distributed water.
The Museo del Agua y de la Historia Sanitaria is housed within the Palacio de las Aguas Corrientes, a landmark building completed in 1894 to distribute water to the city. The structure is world-renowned for its eclectic exterior, which is entirely clad in over 300,000 glazed terracotta tiles imported from Royal Doulton in England. Initially designed as a massive water tower to improve public health, it once held 12 tanks capable of storing 72 million liters of water. Today, the museum showcases historical water-pumping equipment, plumbing artifacts, and the evolution of sewage systems in Buenos Aires. Visitors can explore the preserved industrial machinery and exhibits detailing the city's 19th-century sanitation engineering. The building serves as an active administrative hub for AySA, the municipal water and sanitation utility company. It is located in the Balvanera neighborhood on a site previously occupied by a railway terminal. It remains one of the most distinct examples of Victorian industrial-administrative architecture in South America.
