Drinking Water in Mexico City Is it Safe

Can You Drink the Water in Mexico City?

Technically, you can drink the water in Mexico City. However, we strongly advise against it since it’s not safe. While Mexico City has a purified water source, the distribution remains questionable. 

In worst cases, the pipes can be contaminated and affect the safety of the water for drinking. For this reason, it’s best to play it safe by avoiding tap water for consumption. Generally, it’s best to keep drinking bottled water throughout your stay in Mexico City.

How Safe Is Mexico City’s Water?

The tap water in Mexico City isn’t considered safe for consumption, and it’s because of the waterways that distribute it to consumers.

The same thing applies to all areas of the city. As a tourist, you’re not used to the elements and contents of the water in the city. As such, even tap water can upset your stomach if you have a sensitive digestive system.

Now, while some Mexican locals drink tap water and nothing happens to them, it doesn’t mean it applies to you. Unlike tourists, these citizens drink tap water daily. As such, they are used to it.

On the other hand, a sudden change in the properties of water can affect your digestion. Therefore, to stay safe, we recommend you keep drinking purified or bottled water throughout your stay in the city.

Sources of Mexico City’s Water

The primary source of Mexico City’s water comes from the underground aquifer and reservoirs several kilometers away. This source serves all the areas of the city, which houses more than 20 million residents. 

While the reservoirs and aquifers offer safe drinking water, the pipes that distribute these waters may cause contamination. As such, it’s always best to stay safe by drinking purified or bottled water.

Most locals source their drinking water from water stations. They buy water packed in five-gallon containers. Such containers are refilled and delivered to their homes.

On the other hand, some locals use water filters on their faucets to filter out the water, making them safe for consumption. However, it’s pretty unusual for Mexicans to have such.

Now, when it comes to hotels, the source of drinking water is bottled water and water-refilling stations to accommodate their customers.


Most establishments take the extra mile by covering complimentary drinking water for their guests to ensure they don’t drink tap water. 

Some hotels might provide bottled water in the rooms upon entry. Most hotels offer it complimentary, while others charge for it when you consume the water.

If you’re out, you can always buy drinking water in convenience stores, local stores, groceries, restaurants, and other establishments. You can even find cheap water bottles from road and street vendors.

If you’re wondering about the ice used in drinks, you can ensure that most establishments use purified water to make the ice. As such, they are safe to consume and mix with your drinks.
