Source of Water in Mexico City, Mexico

Most of Mexico City’s tap water comes from groundwater pumped from aquifers beneath the Valley of Mexico. The city also receives water from the Lerma and Cutzamala systems.

These systems bring water from basins west of the city, including reservoirs in the State of Mexico and Michoacán. The water is treated before it enters the municipal distribution network.

Mexico City Drinking Fountains

Public drinking fountains in Mexico City are not consistently maintained or monitored, so do not assume the water is safe to drink. Although the municipal supply is treated, aging pipes and building or fountain plumbing can affect water quality.

Choose sealed bottled water or water from a clearly maintained, filtered refill station instead. If a fountain looks dirty, damaged, or poorly maintained, avoid using it.
