How much water you need depends on a lot of things and varies from person to person. For adults, the general recommendation from The U.S. National Academies of Sciences, Engineering, and Medicine is about:

11.5 cups (2.7 liters) a day for women
15.5 cups (3.7 liters) a day for men

This includes fluids from water, beverages like teas and juice, and from food. You get an average of 20 percent of your water from the foods you eat.
