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.

Venice: we filter it first via some cheal filters. It is very common to own a water mug with a filter embedded here.

Paris: directly from the tap water, though I don't like the taste.

in Brazil de usually dont boil, but use a traditonal ceramic pot filter.

[–] vacuumflower@vlemmy.net 3 points 2 years ago

Moscow, Russia. You can usually drink tap water in Moscow, but it's something unusually good for Russian bigger cities in general, and it's considered a good thing to boil it. Actually depends on local specifics and where the water comes from.

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

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.

[–] KuroJ@lemmy.world 3 points 2 years ago

I’m located in the US and like others have said it’s safe to drink the tap water, but me personally, I run my water through a filter first.

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

[–] GoodPointSir@lemmy.ca 3 points 2 years 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.

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.

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.

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.

[–] computerfan0@beehaw.org 2 points 2 years ago

Irish person here. Yes, I drink my tap water without boiling. My water comes from a well as I live in a rural area, but town/city water is drinkable too.

[–] Iconoclast@slrpnk.net 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 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.

[–] f5xs_bhw0a@beehaw.org 2 points 2 years ago

In the Philippines, we don't drink from the tap. At all. It's quite dangerous and there have been a number of internet personalities that got stomach aches from drinking tap water ^cough^ ^haachama^ ^cough^

Instead, there are a lot of establishments here that sell drinkable water at a fraction of a dollar per 5 gallons.

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

[–] 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.

[–] GONADS125@lemmy.world 2 points 2 years ago

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.

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.

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. I’m looking to get a whole home water filter installed to remedy that.

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

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

[–] mintyfrog@lemmy.ml 2 points 2 years ago (3 children)

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.

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.

[–] 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.
