As a general rule, adult males need 3.7 liters of water per day, while adult women need 2.7 liters per day. However, pregnant women should aim for 3 liters per day, and lactating women need 3.8 liters per day. The daily adequate intake of water is lower before the age of 18. From birth to 12 months of age, infants need just 0.7 to 0.8 liters per day -- which is easily achieved through breast milk alone. The daily intake increases to 1.3 liters from age 1 to 3 and 1.7 liters from age 4 to 8.
The report did not specify exact requirements for water, but set general recommendations for women at approximately 2.7 liters (91 ounces) of total water -- from all beverages and foods -- each day, and men an average of approximately 3.7 liters (125 ounces daily) of total water.
