On your daily log page at the top is water.  I set me for how many glasses I drink a day  not each glass.  

Caffeinated tea and other caffeinated beverages are diuretics, negative water, though.  You would not log it as water, and for every ounce you drink you are supposed to drink an extra ounce of water.  I don't bother logging beverages, but I log stuff I put in them.
