I'm from Chile and we drink tap water without boiling. Some people buy filtered water because they dont like the taste, not because is unsafe.

It shocked me when I visited Peru and Mexico and realized that tap water is not safe there.

I live in the USA, and we don't have to boil tap water in my city, but after having lived for a spell in a place where tap water is boiled first, I boil mine because I like the way it tastes--it's sweeter. Maybe boiling it helps get rid of the chlorine taste that city water has? I don't know. But I do prefer it.

I never drink water out of the tap because I prefer to filter it first. It’s safe to drink but I want it clean and much colder so into a filter pitcher and put that in the fridge

Quebec, Canada. I grew up in a rural area where we had our own artesian well on the plot of land, so not attached to any city infrastructure, and no purification process at all, except what is done naturally from the soil. And guess what? It's the purest water I've ever seen, it taste amazingly fresh and the tap is directly plugged on it.

Moved to a big city and now have to use the city infrastructure, which of course have a huge purification plant and they do tests continuously to make sure it pass a high quality threshold. But even if it's probably cleaner than 90% of the rest if the world, it still have a slight unpleasant taste. I could probably buy a filter, but never bothered.

Buying bottled water is seen as wasteful and also a scam since it's often just tap water they bottled. When my family visited a country where bttled water is common, they were disgusted at how much plastic pollution it creates.

I would hate to have to boil water before every usage, I assume you always keep a few gallons in the fridge to keep some cold? It takes space and energy to prepare, must be annoying. But what I wonder the most is, how to do wash yourselves and your clothes? If the water smells foul, doesn't taking a shower just stink you even more than it cleans?

Luxembourg here, i'll drink straight from the tap.

We drink straight from the tap here in Scotland. It's great water.

In Rome there are literally fountain running constantly in the middle of almost all the streets(old area specially ) of potable whater. Again non stop, people use them allot

The further I searched, the more it seems to me that in developed countries (like US, Canada and the above examples), tap water is safe to drink directly. Is that true? Do you drink tap water without boiling?

Yes. It's a bit of a scandal when that's not true. (Canada here)

And to my surprise, I checked the Water Supplies Department website and notice it asserts that tap water in Hong Kong is potable, like many well-developed countries and regions.

Boiling it has to be "force of habit", then. I wonder how long it's been potable. I'm guessing mainland China is mostly boil-first.

Generally in the west (US/Canada, and most of Europe) tap water is safe to drink. I've been to Iceland and don't remember tap water being a concern. This is something you should double check before every trip though. A good rule of thumb is just going by how developed/rich the country is that you are visiting, with more developed countries usually having potable tap water but this is not a guarantee. (And some countries are far too large and diverse to apply this rule efficiently)

Also asking the locals is not necessarily a good idea either as there immune system might be accustomed to the different bacteria and pollutants in the water. For example drinking tap water in some places in the Middle-East might not be an issue for the locals but as I haven't grown up there I probably wouldn't risk drinking tap if I can avoid it, not to ruin the trip with getting sick.

TLDR: check with your country's official travel recommendations

Edit: someone mentioned bottleded water just being bottled tap water. While this is not uncommon in Europe (not sure about the rest of the world), the water does go through extra steps of filtering and cleaning meaning it might be a bit safer to foreigners.

Canadian in a major city - yes, safe to drink right from the tap.

However, many remote communities here do not have access to safe drinking water.

From Singapore. Tap water here is potable but we boil it first out of habit. (But I use tap water for drinking when boiled water has run out).

Australian here, never met anyone who boils tap water before drinking it. Some people have filtered water taps installed but our tap water is usually pretty great, I drink probably 2-3 litres of it a day

Croatia here,

tap water is completely drinkable and safe without any boiling. Exception are some more remote islands, so if you are going on some island, chekc if the tap water is drinkable.

Fun fact: Croatia actually uses drinkable water for toilets as well, altough i would not drink from a toilet :)

In the UK they had separate taps for hot and cold because the cold was safe to drink and the hot was not.

Belgium: yes! We drink tap water. Straight from the tap. Hardness varies from city to city. At my home I have a filter to make the water softer. That helps the taste but also keeps all faucets etc running.

You can drink the tap water in most places in Iceland without boiling it (especially in Reykjavik), but if you're further into the countryside then I would check first!

Poland here, tap water is pretty drinkable in cities, not sure about rural areas though, also I personally use Brita filter just to be sure

Depends on how acclimated your stomach is. Locals may be able to drink without problem but foreigners may have stomach problems.

Just ask someone from there on day one. They can obviously tell and i think this is the best strategy. I bet it's safe like in most parts of middle and northern europe.

I live in the US in a location where the tap water is safe to drink (not always the case, e.g., Flint Michigan) but I still filter it for the taste (chlorine in the water).

Most municipal water is safe to drink in the US. Ground water depends entirely on where you live and many situational factors (City pollution, water level, etc.).

We will get boil notices from time to time when a contaminant is detected in the water supply. But that's been rare in my experience, after living in several regions in the US.

No one should ever use tap water for netty potting without boiling it though! You can contract a brain-eating amoeba if you don't boil, which has over 97% death rate.

Hungarian here. It is safe to drink without boiling. People only boil water for baby formula to be extra safe.

I'm from Denmark, and water is safe to drink straight from the tap here.

In Argentina, generally you can drink straight from the tap.

In Malaysia, the water is advertised as safe to drink. Large majority however, either boils it or uses their own water filters.

German: Yes. Most of the water I consume comes straight from the tap

No, I never drank unfiltered tap water. I have always lived in areas with poor-tasting tap water. It's not necessarily dangerous, but has a high calcium content and isn't the cleanest either.

As a kid, we had a carbon filter on our refrigerator, and that was good enough. When I moved out of my parents house, I started getting those 5 gallon bottles and would refill them at the grocery store.

I eventually got my own refrigerator that had a carbon filter, but I couldn't really go back to a carbon filter once I got used to water filtered by a RO system. It just didn't taste very good. So about a month ago I installed a RO filter under my sink, and now I don't need to drag my bottles to the store anymore. Best of both worlds!

One thing to consider: While tab water in most of the developed world is potable,any water safety guarantees usually end where the house water pipes begin. Depending on the state of the piping, tap water might not be safe, even if the water supplyer says it's safe.

You can get a water test (especially bacteria is important) for relatively cheap. Last time I did such a test it was ~€60. It's not wrong to do one.

Also, the definition of potable water is that the water is potable after the tap has been running for 10(!) minutes.

Bacteria contaminated pipes are pretty common and if the water has been sitting in these biofilm-covered pipes over night or even longer, the water can become pretty harmful. Especially after you get home from a vacation, letting the water run for a decent amount of time might be a good thing.

Also: the worst thing that can happen to your water pipe system are blind pipes, so pipes that are connected only on one end. That could be e.g. left-over plumbing after remodeling or pipes that lead to unused taps. If at all possible, these ahould be removed or flushed at best daily.

In Canada most people drink water after filtering through a Brita, but it's safe to drink without.
