Our family lives in Pozzuoli, right on the Gulf of Naples, and uses a water filter. Not because the water there is officially considered unsafe, but simply because full trust in its quality is hard to come by. Whether this is representative of southern Italy in general is difficult to say, but it reflects how many people who live permanently in southern Italy handle the situation. The question of whether tap water can be drunk in Italy has no simple answer. It depends on where one happens to be.
Officially, it is safe to drink
Italy is an EU member state and subject to the European Drinking Water Directive. According to the national water quality monitoring center, CeNSiA, Italian tap water meets health-related quality parametersin 99 percent of cases. That is an impressive figure, and yet millions of Italians reach for a bottle every day. There are reasons for that.
North and South are two different worlds
In northern Italy, especially in the Alpine regions and cities such as Milan or Bolzano, tap water is considered excellent. It often comes directly from mountain springs, is soft, and tastes good. Anyone vacationing or living there can drink straight from the tap without a second thought.
The further south one travels, the more the picture changes. The infrastructure is older, the pipes are partly deteriorating, and chlorine levels are higher in summer because the water requires more intensive treatment. Sicily faces an additional challenge: many buildings have rooftop water tanks that can become breeding grounds for bacteria in extreme heat. On top of that, the south is increasingly struggling with water scarcity . In 2024, more than one million residents were affected by rationing measures, a marked increase compared to the previous year.
Campania, where Pozzuoli is located, is one of the regions with the highest water consumption in all of Italy. The water is safe to drink, but taste and pipe quality in older buildings can vary considerably.
The chlorine issue
One point that surprises many visitors: even where the water is technically flawless, it often tastes strongly of chlorine, especially in summer when temperatures rise and treatment is intensified. This is not a safety concern, but it is one reason why many people prefer bottled water.
The Nasoni, Rome's liquid heritage
Anyone exploring Rome will encounter the so-called Nasonieverywhere, the small cast-iron drinking fountains that continuously flow with fresh water. The water comes from ancient aqueducts and is considered excellent. Those who carry a bottle can simply refill it there, free of charge, cold, and good.
For visitors
Those spending a week in Tuscany, on Lake Garda , or in northern Italy can drink the tap water without hesitation. In the south and on the islands, more caution is advisable, especially in older buildings or when the water has an unusual smell or taste. Bottled water is inexpensive and available everywhere in Italy. A liter of mineral water at the supermarket often costs less than 30 cents.
For those moving to Italy
Those who live in Italy long-term tend to develop a feel for local water quality fairly quickly. A good water filter is a worthwhile investment, particularly in the south, not necessarily for safety reasons, but because it noticeably improves both taste and pipe quality . Our family has not regretted making that choice.
