Is Tijuana Tap Water Safe To Drink?
No, it's not advisable to drink the tap water.
Tap water in Tijuana is treated under Mexico’s drinking-water standards, but quality can vary because of aging infrastructure, service interruptions, and possible contamination in local distribution systems. For this reason, untreated tap water is generally not recommended for drinking, especially for visitors.
Use commercially sealed bottled water or tap water passed through a certified filter designed to remove bacteria and parasites. Boiling tap water for at least one minute is another effective option, and bottled or treated water should also be used for brushing teeth.

Source of Water in Tijuana, Mexico
Tap water in Tijuana is supplied mainly by the Colorado River through the Colorado River-Tijuana Aqueduct. The water is conveyed from the Mexicali Valley west to Tijuana, where CESPT treats and distributes it.
Local groundwater wells and the Abelardo L. Rodríguez Reservoir provide additional supplies, especially during periods of high demand or limited deliveries. Before reaching customers, the water is processed at municipal treatment facilities and disinfected.
Tijuana Drinking Fountains
Public drinking fountains in Tijuana are not generally recommended for drinking unless they are clearly labeled as potable and visibly well maintained. Municipal water may meet Mexican safety standards at treatment facilities, but contamination can occur in distribution systems, storage tanks, and poorly maintained fountains.
For reliable drinking water, use sealed bottled water or water from a properly maintained certified filtration system. Do not drink from fountains that are dirty, damaged, stagnant, or lack clear potable-water labeling.
