Presumably, you are drinking that much water on medical advice. You shouldn't be consuming that much otherwise.
The NHS advice is that women need on average, around 1.6 litres of fluid (of all kinds) per day and men need an average of two litres to keep their bodies working efficiently. Those amounts include the liquids contained in your food, and in any tea or coffee that you drink.
Unless there's a medical need, consuming more than that will provide no additional benefits and could cause harm if consumption at that level is habitual.
