La Casa de l’Aigua de Trinitat Vella

Barcelona’s water supply system formerly included pumping stations such as Casa de l’Aigua de Trinitat Vella. The station was used to collect water from wells in Montcada i Reixac and then pump it to the tank in Trinitat Nova, where it was treated and channelled to supply much of the city.

Running water, modern city

The station was built by the architect Pere Falqués in 1915, after a typhus epidemic had broken out in the city precisely as a result of contaminated water. The Modernista-inspired structure was built on the grounds of today’s Parc de les Aigües in the Trinitat Vella neighbourhood and entered into service in 1919. Casa de l’Aigua remained operational for most of the century and its pumps were stopped only once for about a year due to the floods in 1962.

A building at the neighbourhood’s service

The Museum of History of Barcelona, together with different institutions in the Sant Andreu and Nou Barris districts, is working on a process to adapt all the facilities and open them to the public. The goal is to make it possible for visitors to view the main facilities, such as the Trinitat Vella pumping station and water tank and the pipes that connect them and the rest of the city, in order to show how the supply of drinking water to large cities worked. Casa de l’Aigua has housed a vocational training centre since the early twenty-first century and also gave its name to a new underground station when the Metro reached the neighbourhood in 2003.
