Human uses of water
About 72% of the fat free mass of the human body is made of water. To function properly the body requires between one and seven litres of water per day to avoid dehydration, the precise amount depending on the level of activity, temperature, humidity, and other factors.

However, most of this is ingested through other foods or beverages (hot tea being often used in deserts to avoid dehydration, etc). It is not clear how much water intake is needed by healthy people.
