It depends: The answer to this question is not easy as water intake depends on your health, how active you are and where you live ( temperature outside) . Just remember that water constitutes 60 to 70 % of your body mass and roughly for a 70 kg man he requires 3 liters ( 13 cups) of water per day whereas women with the same weight require 2.2 liters ( 9 cups).
