Or just bring an empty bottle through and fill it up at the tap/water fountain?
Some people think tap water tastes bad
I wouldn’t drink tap water outside of continental Europe. Maybe the original OP is simply in a third world country like the US.
Canada’s is good in major cities
The tap water in Canberra, Australia is the tastiest I've tried out of the ~20-50 municipalities I've sampled in Australia, Western and Southern Europe, the US, China, Taiwan and Vietnam.
It tasted better in Canberra before the 2013 bushfire, back when it was filtered through pine needles, before they removed all the pine farms
Indeed. You can tell if it’s straight out of Googong Dam also.

Ah, dang. Yeah I was there before 2013 and it was so noticably delicious. The friend I was visiting said it was the first thing her mother had said when visiting as well, how good the tap water was.

Bummer to hear that's changed!

Update: It was actually 2003, I was in Theodore at the time. It’s recovered mostly from that bushfire as well as the 2019/2020, when I was visiting while it was happening.

Search term from the immediately above link is, ‘why was Canberra’s water so good before the bushfire?’

I have been living in Melbourne since 2017. Canberra’s water still just pips it (Silvan Reservoir area), thanks to the Corin and Bendora dams. Googong water is still terrible (it has a slightly bitter taste, probably because of chlorination treatment) when water from it is required, but they haven’t had to use that for a while. It’s night and day to me, at least when Googong water is involved.

Canadian tap water is generally good

Outside of Continental Europe

Oddly specific when of the 10 countries judged to have the equal best tap water quality, 4 are European islands (UK, Ireland, Iceland, Malta) and many Continental European countries score behind the US:

I wouldn’t trust the plumbing in the UK. They do crazy two-faucet stuff.
That two tap stuff makes the cold water safe. Don’t drink from the hot tap where they don’t dare mix hot and cold
Fuck off, racist piece of shit.

The US has pretty good tap water in most places. Of course there are outliers we are talking about a giant country.

While you are right to trust most tap water in Europe we also have a lot of outliers. Old plumbing being probably the biggest problem. But also the taste can be atrocious. The worst tasting tap water I ever needed to drink was in Barcelona.
