Yes. Tap water in Milan is safe to drink, so there is no need to spend your trip carrying large bottles of water back to your hotel.
Milan’s drinking water is regularly tested and must meet Italian drinking-water standards. MM, the company responsible for Milan’s water system, monitors the water from the underground wells through the treatment system and distribution network. The local health authority, ATS Milano, also carries out independent controls.
So if you are filling your bottle before heading out to see the Duomo, walking around Brera or spending the afternoon in Navigli, the kitchen tap is normally all you need.

Where does Milan’s tap water come from?
This is one of the more interesting things about Milan’s water.
The city gets 100% of its drinking water from underground groundwater beneath Milan rather than from a river or lake.
MM operates hundreds of wells connected to pumping stations around the city. The groundwater is naturally filtered as it passes through layers of soil before being collected, treated where necessary and sent into Milan’s water network.
It is also tested extensively. MM says its laboratory performs more than 3,600 water samples each year and analyses almost 170,000 individual parameters. Monitoring takes place at the wells, treatment plants and throughout the distribution system.
The City of Milan also publishes current water-analysis data, including results divided by different areas of the city. The 2026 dataset is updated monthly.
For a traveler, however, the answer is much simpler:
You can drink it.
Why does Milan tap water sometimes taste different from bottled water?
Safe and delicious are not always exactly the same question.
Milan has relatively mineral-rich water. Its average hardness is around 27 French degrees (°F), mainly because of naturally occurring calcium and magnesium.
You may therefore notice more limescale around a kettle or bathroom tap than you are used to at home.
That does not mean the water is unsafe.
Hardness mainly affects things such as limescale and taste. It is not a sign that the water is contaminated.
Some visitors also notice a faint chlorine smell occasionally. Milan’s water does not require heavy disinfection, but MM says very small amounts of sodium hypochlorite may be added as a precaution.
If you notice the smell, MM recommends pouring the water into a jug and leaving it for a few minutes.
Putting it in the fridge also makes Milan tap water considerably nicer on a hot summer day.
Can you drink tap water in Milan hotels and Airbnbs?
Normally, yes.
If your hotel, apartment or Airbnb is connected to Milan’s normal municipal water supply, the water supplied to the building is potable.
There is one small distinction worth understanding, particularly in an old city.
MM is responsible for water quality up to the building’s delivery point. Once the water enters the building, the internal plumbing belongs to the property or condominium and its maintenance is the responsibility of the owner or building administrator.
That does not mean you should be suspicious of every old Milanese palazzo.
It simply means that if the water coming from your particular tap looks rusty, has an unusual smell or seems obviously wrong, do not assume that this is normal “Italian water.” Ask your hotel or host about it.
The municipal water itself is safe to drink.
Do you need a water filter in Milan?
No, not for safety.
MM specifically states that the drinking water supplied by Milan’s water system does not require additional domestic purification.
Some residents use filters because they prefer the taste or want to reduce limescale, but that is a matter of preference rather than something travelers need to worry about.
For a short visit to Milan, buying a filter jug or relying on bottled water is unnecessary.
A reusable water bottle is much more useful.
Can you drink from Milan’s public fountains?
Yes, and you should know what to look for.
Around Milan you will see small green cast-iron drinking fountains with water continuously flowing from a dragon-shaped spout.
They are called vedovelle, although you may also hear them called draghi verdi, or green dragons.
The water coming from these fountains is the same municipal drinking water supplied to buildings in Milan, and MM states that it complies with drinking-water standards.
There are hundreds of them scattered across the city. Milan’s official open-data portal counted 674 fountains in its 2025 overview, with the underlying dataset continuing to be updated regularly.
They are particularly useful if you are exploring Milan on foot during July or August.
Instead of buying another plastic bottle every couple of hours, bring one reusable bottle and refill it as you walk.
Why are Milan’s fountains always running?
The continuously running water can look strange if you come from somewhere where public fountains normally have push buttons.
It is intentional.
MM explains that the continuous flow helps prevent water from stagnating around the fountain and also plays a role in the functioning of parts of the water network. The combined amount used by the fountains is small compared with the total amount moving through Milan’s aqueduct system.
So you do not need to search for a hidden button.
There isn’t one.
Hold your bottle under the little dragon and fill it.
What about PFAS in Milan’s drinking water?
PFAS have become a much bigger subject in Italy in recent years, so it is reasonable to wonder about them.
MM has included PFAS in its monitoring programme since 2021. According to its published results, 1,286 PFAS monitoring tests were carried out during 2025, and the levels recorded in Milan remained well below the legal limits. MM says PFAS were almost always absent or detected only at very low levels.
Milan’s water continues to be monitored as drinking-water standards and testing requirements evolve.
Is bottled water safer than tap water in Milan?
There is no reason to assume that it is.
ATS Milano notes that both tap water and bottled mineral water are subject to safety controls and says there is no scientific evidence that bottled water is healthier or safer than tap water.
Italy certainly loves bottled mineral water. Restaurants will almost always ask whether you want naturale or frizzante, and supermarkets have entire aisles devoted to it.
But that is not because Milan’s tap water is unsafe.
At your accommodation, you can drink from the tap.
When you are walking around the city, you can refill at the green vedovelle.
And if you order a bottle of sparkling water with dinner, do it because you want sparkling water with dinner, not because Milan’s tap water needs to be avoided.
A few useful Milan water tips
Bring a reusable bottle. Milan is an easy city for refilling it, particularly once you start noticing the green fountains.
Drink from the cold-water tap. This is the normal choice for drinking and filling bottles.
Don’t worry about limescale. Milan’s relatively hard water can leave mineral deposits, but hardness does not make the water unsafe.
A slight chlorine smell does not automatically mean something is wrong. Let the water sit in a jug for a few minutes if the taste bothers you.
Pay attention to the individual building. If water from a hotel or apartment tap is visibly discolored or has a genuinely unusual smell, ask the property before drinking it. Problems with internal plumbing are different from problems with Milan’s municipal water supply.
Use the vedovelle. They are free, practical and one of those small pieces of Milan that become much more useful once you know what they are.
So, can you drink the tap water in Milan?
Yes. Milan tap water is safe to drink.
You can drink the water in your hotel or apartment, fill your bottle from the tap and use Milan’s public green drinking fountains while exploring the city.
There is really no need to spend your Milan trip buying plastic bottles of water.
Save those euros for something more worthwhile.
An espresso will do nicely.
