That depends on the comfort level you want and the surroundings.

Drinking water
Under normal circumstances, you need 1.5 to 2 litres of water every day. Part of this will come with your food or beverages. In a dry hot climate you will lose more water through perspiration, so you will need more, up to 9 litres a day (but there are ways to avoid water loss, like staying in the shade).

Water for cooking
Most foods need at least a bit of water to be cooked in (or steamed). If you don't throw away the water, but use it for a soup, you can add that to your drinking water.

Those were the essentials, without which you cannot survive in the long term.

Then, of course, there is "luxury" water:

  • Cleaning
  • Bathing/showering
  • Flushing your toilet
  • Washing your car
  • Etc, etc

Water use in the UK is about 150 litres per person per day!
