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 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.

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

[–] Foon@beehaw.org 2 points 2 years ago

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 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.

[–] TONKAHANAH@lemmy.world 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.

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.

In USA yes, we drink tap water without boiling as long as we're in an area with safe tap water (most of the population) and not using our own untreated/untested well water. Every once in a while we get alerted to local unsafe tap water. We have a filter on the tap water but haven't always.

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

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 2 years ago (2 children)

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

Tastes great right from the tap.

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.

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

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.

Canada here - I drink water straight from the tap.

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

[–] PetrusHyde@lemmy.ml 2 points 2 years ago (1 children)

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).

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.

[–] JaneDoe@lemmy.ml 2 points 2 years ago

In France tap water is drinkable and good almost anywhere, the exceptions being in some cities during drought or due to unusual pollution. I actually dislike most mineral bottled water because I find it tastes like something.

I used to live in Thailand, while the authorities say the water is good you'll likely get sick if you drink water straight from the tap. I used to buy my water from a filtering machine near my condo.

[–] juliebean@lemm.ee 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.

[–] sajran@lemmy.ml 2 points 2 years ago

You can safely drink unboiled tapwater in most places in Poland.

US/Canada here as well as someone that has visited most of western Europe (UK, France, Netherlands, Belgium, Luxembourg, Germany, Switzerland) and stayed in hostels - no boiling necessary in any of these places.

There's actually a pervasive myth I've encountered that hot tap water is dangerous and that one should only drink cold water. As far as I'm aware, this myth is due to an old setup for water systems that many western homes had before modern taps. The tap was separated into separate cold/hot faucets. The cold water came safely from the city, but the hot water came from tanks that were stored in people's attics. The water in these tanks sat stagnant and was therefore prone to rats and other creatures dying in it or bacteria building up. This is why still today, most British homes have separate hot/cold taps - to keep the "safe" water separate from the "dangerous" water. I occasionally encountered such taps in the US and I assume that's why my dad raised me to make sure the water was cold before drinking it. My father's understanding of this was clearly outdated though. I learned all of this from a Tom Scott video.

Yes. Here in Portugal, water is drinkable without boiling. Of course, water quality varies from region to region, but as it happens, where I live it's quite good :)

[–] BendyLemmy@lemmy.ml 2 points 2 years ago* (last edited 2 years ago)

This is crazy - for sure, in many countries it can be taken straight from the tap depending on the reliability of infrastructure... but to waste energy boiling it??? No thanks.

In England, I moved a few times - some places have great tasting water - others not so great - meaning it's always safe (and ok for brewing or cooking) but not so good for drinking from the tap.

In Scotland (a couple of places I stayed and worked) it's a toss up whether you should drink the tapwater, or go to your local and take another dram from the top row.. those Single Malt Whiskeys made with water from Scotland are amazing... but both are safe in moderation.

In Bangkok, if I don't clean my shower out monthly, it ends up with brown gunge building up, so I certainly don't drink the stuff... and it's hard to know how clean it is (though we're told it's certainly drinkable at source, it has a long way to come to my house - and the pressure of the system is low... another red flag). Visiting tropical islands, you see some resorts are connected via long plastic pipes which are often on the surface (in the sun) and so definitely not the best candidate for anything more than a shower.

In Bangkok too, unless you can test it yourself you shouldn't drink it - but I fail to see why you'd decide to boil dirty water and drink it, seeing as most countries with inadequate tap water have drinking water.

I wouldn't use 'boiled tap water' to make my pasta either.

I have six large bottles which gets topped up each week, to make sure I have plenty of water to cook and drink with... If I didn't, then I'd invest in a good water filtration system.

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.

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 didnβ€˜t drink tap water (I was warned), but I mindlessly used it for brushing teeth and that probably ruined my last few days there.

[–] HobbitFoot@thelemmy.club 2 points 2 years ago

One thing about tap water in the USA is that, while you can drink it, water taste varies a lot.

For instance, in the Southwest USA, it is very common for bottled water to be sold in gallons. There are even small stores whose main purpose is to filter tap water to remove minerals.

You also have the use of non-potable "grey" water that is treated sewage water that gets used for irrigation. You'll usually see signs to not drink that water.
