Madrid’s water is a source of pride and memes in equal measure, but the reality is that you can drink tap water in the capital. Now, Canal de Isabel II, the agency responsible for managing Madrid’s water supply, is opening its facilities to visitors for the first time in an organized manner.
The tour takes visitors to the historic facilities of Canal de Isabel II, its headquarters in Santa Engracia, the exact spot where water from the Lozoya River first began flowing into the capital in 1858. To mark its 175th anniversary, the public company will hold an open house with free guided tours on March 21 and 22, with four morning sessions (10:00 a.m. and 12:00 p.m.) and very limited capacity: just 540 spots in total.
For about 90 minutes, visitors will tour these historic reservoirs, see the old pumping station, and hear directly from the workers themselves how one of the world’s most important urban water networks was designed and evolved. It is a unique opportunity to see the inside of infrastructure that is normally off-limits and to understand how water became a continuous and modern supply in the middle of the 19th century.
What the tours will be like and who can attend
The tours are designed for people aged 14 and older and will be led by Canal de Isabel II staff, who will serve as guides through underground galleries, old reservoirs, and technical rooms, combining historical explanations with details on how the integrated water cycle works today. Advance registration is required and opened last Friday via this link; each person must reserve a spot in one of the four time slots, all of which are in the morning, but for now they are all full.
Those who secure a ticket will also be able to catch a rare glimpse of the Lozoya River spring in Bravo Murillo, thus completing a tour that blends industrial heritage, 19th-century engineering, and environmental awareness right in the heart of Madrid.
