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.

    US here. Yes, can confirm I can, and do drink water from the tap without boiling. The city provides, maintains, and regularly checks the safety of the water. Notices are put out if something damages the pipes and a “water boiling” policy is put out promptly over local radio and/or newspaper.

    Lol, I was you 10 years ago. For context I’m Malaysian and we only drink water that is first filtered and then boiled. When eating outside we generally avoid iced drinks unless it’s a reputable shop.

    Then I moved to Australia and reacted with utter horror to see my then-bf drink straight from the tap. I was like wtf you’re going to get parasites! Spit it out!

    Now I drink water like Aussies and my kid refills her bottle from the tap too. My parents, when they visit, still boil water to drink but they’ve at least stopped thinking we’re trying to murder their grandchild.

    Berlin, Germany: we drink water straight from the tap. It’s free and delicious. If you don’t feel like drinking tap, just drink a “Berliner Rohrperle”. It’s the same thing with a fancier name, because our tap water is awesome.

    Nowadays we even have public drinking fountains dotted around the city.

    México. NO. Do not drink the tap water. Boiling does not help. It has a bunch of heavy metals and other contaminants in it. It sucks because mechanical filtering is incapable of removing them effectively. Reverse osmosis does but it is a challenging and expensive process to properly keep in your house. We always buy bottled water. Trucks deliver twice a week.

    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 the US, the only time you’d have to boil water before drinking in most places is if there’s something wrong with the water system and they put out a “boil water” advisory, and that’s pretty rare. It’s definitely not something you have to on a daily basis. Some people will use water filters but it’s not usually a necessity.

      Very true. However in the less urban areas there is often well water which varies by jurisdiction from drinkable to toxic (even flammable!) Also some places in the US have water that is unsafe to use even if it was boiled. Usually water is handled on the local level and can be different depending on the local government’s ability, wisdom, and funding.

    In this US, yes, we generally trust our tap water (although there have been notable incidents of water infrastructure failures, such as major lead contamination in Flint, MI), to the extent that if you get a drink in a restaurant here, 99% of the time it’s going to be mixed or made using tap water, with ice made from tap water.

    Some folks will use a filter (Brita brand filter pitchers used to be popular at one time, with TV ads and everything) but that’s more for filtering out chemicals/toxins/minerals than anything else.

    In rural places, every now and then the local government or water company (yes, a lot of places here have privatized water infrastructure which is not super great) will put out a ‘Boil Water Notice’ but this is generally considered outside of the norm, and you usually expect to see that kind of stuff resolve within a couple of days unless it’s a result of a major disaster (we were under a Boil Water notice for 2 weeks after hurricane Katrina in my area, the longest stretch I ever remember). Boil Water notices are usually a result of either a breach of the infrascture (a pipe collapsing and the water supply getting dirty), or a water supply failing its regular quality/safety tests. Our water (can’t speak for everywhere in the US, and don’t really know the specifics of how they do it) is chemically treated and filtered before it goes into the tap, and the supply mechanisms are usually regularly tested to make sure they’re within safe standards.

    All of that being said, I know people who refuse to drink tap water, mostly because it tends to have a distinct taste from treatment and from having minerals in it, but also because they’ve heard horror stories like in Flint. Two things: those folks normally drink bottled water, which is usually just bottled-up tap water from some other place; and I usually see those folks gladly drinking fountain drinks/tea/etc at a restaurant, which is made with un-boiled tap water and served on tap-ice.

    TL;DR - the tap water in the US is generally considered safe to drink, in most places, with notable exceptions, and for now (our mostly-privatized infrastructure is getting worse and worse, and very public failures have started to appear in not only water infrastructure, but everywhere)

    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!

    I live in a major Italian city, I’m well over fifty, and I’ve always drunk unfiltered water straight from the tap without boiling. Some Italians apparently don’t like the taste of tap water but it’s still safe to drink it unfiltered and unboiled in nearly all the country.

    UK. Yip. Water “hardness” varies across the country which means people usually prefer the taste of the water in the region they grow up in. Other than all the leaky underground pipes and lack of investment in a privatised service, UK water is actaully very good.

    Manila, Philippines: My drinking water comes from a delivery service that drops off a few blue containers of drinking water every few days. I’ve never swallowed tap water but I do use tap water when rinsing after toothbrushing. The sticker on the blue containers has the company name on it, contact details (obviously), and something about “18-stages latest US technology”.

    Argentinian here, depends on the region of the country, in most places it’s safe to drink tap water although it usually has too much chlorine or in small rural cities like mine sometimes there’s a bacteria leak on the water so we prefer to buy bottled water
