For context, I live in Hong Kong where most people drink tap water after boiling first. Some may install water filter but may still boil the water. Very few drink bottle water unless they're outside and too lazy to bring their own bottles.

Now, I'm researching whether I can drink tap water in Iceland (I'm going there in August), and while it looks like the answer is affirmative, almost no web article mention whether I need to boil the water first. People in Japan (a country I've visited a few times) also seems to be used to drink tap water directly without boiling.

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?

It sounds like a stupid question but I just can't believe what I saw. I think I experienced a cultural shock.

Edit: wow, thanks so much for the responses and sorry if I didnt reply to each one of you but I'll upvote as much as as I can. Never thought so many would reply and Lemmy is a really great community.

2nd Edit: So in conclusion, people from everywhere basically just drink water straight out of tap. 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.

However, as the majority of Hong Kong people are living in high-rise buildings, a small amount of residual chlorine is maintained in the water to keep it free from bacterial infection during its journey in the distribution system. Therefore it is recommended to boil the water so that chlorine dissipates.

So, in short, I actually do not need to boil the water unless I hate chlorine smell and taste. But I guess I'll just continue this old habit/tradition as there's no harm in doing so.

In Lithuania we do not need to boil tap water to drink it and usually it tastes nice unless your plumbing is fucked

[โ€“] [email protected] 2 points 2 years ago

no and no. The tap where I live taste nasy, i think its safe to drink but its not very good so I dont use it.

In Canada, tap water is perfectly fine to drink as is. There are some exceptions when it comes to more remote places, especially in some camping grounds, but they'll tell you or write it somewhere if that's the case.

I went to Iceland last year and the water's very clean and safe! There's no problem drinking it from the tap.

I think you've already had plenty of replies here, but yeah here in western Europe, straight from the tap. I'm also fortunate not to have any chlorine in my water. It's delicious.

One thing about the chlorine, it also just evaporates over time without boiling. Filling a jug of water and leaving it standing around for a while will also get rid of that chlorine smell/taste!

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.

I drink tap water, but ours comes from our private well. We double filter it: sediment then carbon. Back in Costa Rica I also drank tap water, Costa Rica has one of the safest water.

When I was in Cainta, Rizal, Philippines, my uncle always boils tap water before drinking. This is indeed a safety measure. He doesn't buy gallon bottles of drinking water.

[โ€“] [email protected] 2 points 2 years ago

yep, i'll drink straight from the tap. i live in california, united states. it is even common to have drinking fountains in public spaces: special button activated taps that spurt cool tap water into the air for you to drink from.

Modern treatment plants don't use chlorine anymore, they use cloramines that have little scent or taste. This is most likely the case in HK as well.

Boiling water that doesn't need to be boiled is a waste of energy and GHG.

I'm from germany and I drink my tap water without cooking it first, straight from the tap.

[โ€“] [email protected] 2 points 2 years ago

I'm from Italy and i drink tap water since I was child. Never had any problem. But I was told to check tubature aging and materials first, if it's new and not made in lead metal, it's safe.

Most people boil water before drinking here in Singapore. However I personally drink straight from the tap while my wife boils first. Apparently part of Singapore's water is recycled pee but tastes fine to me.

Swede here, we drink the tap water as is (without boiling) all the time and it tastes just as fine or even better than bottled water. When I go to some other countries with supposed safe water then I'm usually shocked by the flavor and don't really trust it.

[โ€“] [email protected] 2 points 2 years ago

German here. Yes, constantly. The only reason to not do it would be taste (personal preference) or sometimes due to pollutants entering the system, which is explicitly communicated by the city.

The tap water is perfectly drinkable in my city but I was raised to drink boiled water coming from a Chinese family. Water straight from the tap tastes disgusting to me.

UK- we don't boil water here unless there's an issue with the pipes. I got told not to drink the water in places like Spain and Italy as it could make me unwell, but not sure if that's as big a deal now.

Where I live in the US, I don't have a need to boil water unless I'm cooking or making tea, and am safe drinking the tap water. I consider myself lucky.

[โ€“] [email protected] 2 points 2 years ago

Austria, yes, water is fine like that I would even drink it in the shower without issue. What is an issue is this habit once made for a bad time in Egypt where I didnโ€˜t drink tap water (I was warned), but I mindlessly used it for brushing teeth and that probably ruined my last few days there.

[โ€“] [email protected] 2 points 2 years ago

I am from the Philippines, and in my city, there are districts that have unpotable water and they resort in using purified water for drinking and cooking. In my district though, water is very potable and we drank it until switching to purified water last year because our water provider got their system contaminated.

[โ€“] [email protected] 2 points 2 years ago

US here. Although we have a water municipality, I still drink bottled water or water through a filter. I had my water tested by third party lab and found out they over chlorinate which leaves a lot of disinfectant byproducts in the water. Iโ€™m looking to get a whole home water filter installed to remedy that.

[โ€“] [email protected] 2 points 2 years ago

US, Colorado - no need to filter or boil the tap water here. One of the benefits of living at the base of the mountains I suppose

Hello Mr Hong Kongnese. I'm a Brit. We don't boil water here and I've visisted Iceland - they don't boil it either.

Diu gau lan tsat hai - Merry Christmas. Enjoy your holiday.

Here in Austria(and some other places in Europe), tap water usually is better quality than bottled water. Even where it isnt, its chlorinated enough so there should be nothing in there to cause any sort of health issues. This seems to be the case everywhere in Europe in myexperience.
