I got that number from here - tried to find a more 'official' source, but water isn't as well documented as energy.

Note that those numbers when I last looked into it typically include industrial and agricultural water use - residential water consumption is usually approximately 15% of total water use, so that fits reasonably.

One problem is that in many countries, water consumers (e.g. farmers) are able to withdraw water from their own soil, and so nobody really knows how much water that is, although it's possible to make educated guesses.
