Source of Water in Lisbon, Portugal

Lisbon’s tap water comes mainly from the Castelo do Bode reservoir, located on the Zêzere River, a tributary of the Tagus. This reservoir supplies most of the water distributed by EPAL, Lisbon’s public water utility.

EPAL also uses water drawn from the Tagus River at Valada and other regional sources when needed. The water is treated at facilities including Asseiceira and Vale da Pedra before entering Lisbon’s supply network.

Lisbon Drinking Fountains

Public drinking fountains in Lisbon are generally safe to use when they are clearly marked as drinking water and appear clean and well maintained. The municipal tap water is treated and regulated under Portugal’s drinking water standards.

Do not drink from fountains marked non-potable, decorative, or temporarily out of service. Let the water run briefly before drinking, especially if the fountain has not been used recently.
