I've only done a small amount of travel outside North America, but, from what I've seen, water is generally less expensive and easier to get in the USA and Canada than elsewhere. One of the more unexpected things I got out of my first trip to Europe was a much greater appreciation for public drinking fountains.
In Western Europe at least, all faucets, unless labelled otherwise, will provide high quality drinking water. This is appreciated when you see some kid licking and slobbering on the drinking fountain in the USA… https://www.tripsavvy.com/tap-water-in-europe-3150039
