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.

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.

Here is Jamaica it is safe to drink the tap water without boiling.

Canada - Many people here put water in the fridge or a britta jug to get rid of the chlorine taste

At home I exclusively drink tap water. I only boil it for tea sometimes :) Iβ€˜m from Germany.

[–] GoodPointSir@lemmy.ca 2 points 1 year ago

Canada here - I drink water straight from the tap.

Although Canadian tap water is some of the highest quality tap water in the world.

I live in Brazil. When I lived on the farm, father set it up so the water would come from a natural underground mine and it was entirely safe to drink. However, in the town, we always bought gallons of packet water instead of using it from the tap. In the city I drank tap water for some years and didn't die, but the taste of the water changed when we began using a filter (thought it was likely that it was because the thing connecting our tap to the system was made out of rubber and a colony of bacteriae began to grow there).

Still, Brazil as a whole is mid risk for intestinal parasites and everyone is recommended to get a filter or packed water by the UN, and also to take anti-vermin medicine once per year.

Bermuda here, straight from the tap!

It actually gets collected from rain water on each individual home's roof. The roofs are lime-washed to kill the really nasty stuff as it runs down in to a holding tank under the house. Some times you get dead critters in there, but nothing larger than a small lizard or bug. They tend to sink to the bottom of the tank, below the outlets.

Most Bermudians swear by a "cup of bleach" thrown down there every couple of years. It's in to a tank that's 10,000gal+ at a minimum (mine's over 40,000), so it's basically homeopathy at that point - but the lime-wash works!

The only place you'll want to avoid it in Bermuda is in the City of Hamilton (mains, not great quality), a house with a dirty roof, or in one near the sole power station on the island. This is an on-going fight to get them to adhere to the emissions safety standards they claim to.

White roofs and smoke stack in the picture!

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.

Spanish here. I drink tap water, but I have a filter installed in the faucet, otherwise it tastes a bit funny (it is drinkable though).

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.

certainly no harm in boiling, but yeah most places in the US I just drink right out the tap if it's public water. Some places are better than others, but usually a filter does the trick. Well water is a whole other story.

[–] mac12m99@feddit.it 2 points 1 year 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.

[–] SillyIce@lemmy.ml 2 points 1 year ago* (last edited 1 year ago)

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.

[–] wildeaboutoskar@beehaw.org 2 points 1 year ago (2 children)

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.

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!

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.

[–] Hundun@beehaw.org 2 points 1 year ago

In Finland I drink straight out the shower head, it's fun and wonderfully safe.

[–] juliebean@lemm.ee 2 points 1 year 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.

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.

[–] TONKAHANAH@lemmy.world 2 points 1 year 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.

[–] nick@campfyre.nickwebster.dev 2 points 1 year ago (1 children)

New Zealand and yes it's safe to drink without boiling here. I do run the tap for a few seconds to clear out any standing water before drinking anything though.

[–] Aaron@lemmy.nz 2 points 1 year ago (1 children)

Also NZ, South island, only time I boil water to drink is for tea β˜•

Tastes great right from the tap.

[–] nick@campfyre.nickwebster.dev 2 points 1 year ago (1 children)

Haha true, although I'm more of a coffee person myself.

I didn't know there was a NZ lemmy instance, I've got some new communities to subscribe to.

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

[–] Pat12@lemmy.world 2 points 1 year ago

When i lived in hongkong i never boiled the water, i just drank it from the tap

USA: Yes, I drink tap water.

[–] neothefox@lemmy.ml 2 points 1 year ago

Here in Armenia all tap water is drinkable as is

[–] kaikanaki@lemmy.ml 2 points 1 year ago

In India generally people use a water purifier to filter tap water before consumption.

[–] Schooner@lemmy.ml 2 points 1 year ago

India here. I can drink tap water without boiling, it just has a slight chlorinated taste. That's why we prefer to filter it, rather than boil.

Asian that’s moved to the U.K. here.

Back home, when I grew up I’ve never drank tap water. In my college days I was way too lazy and started just drinking it with a cheap filter. Surprisingly I survived for 5 years despite everyone around me telling me otherwise.

Now in the U.K. I’ve always drank straight from the tap. It’s surprisingly refreshing! And the boiled water taste I can’t really get used to again when I visit home.

The water in Iceland is safe to drink from the tap. Although if I recall correctly it’s pretty sulfuric due to the local hot springs.

I’ve visited a few countries around Europe and have always enjoyed sampling their local tap.

[–] SomethingClever@lemmy.ml 2 points 1 year ago

Your examples, yes, but I also dont know of any European country where you need to boil the water you drink.

[–] flexcyness@lemmy.ml 2 points 1 year 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.
