How much water is enough water to intake in one day?

Also, i think it's quite dangerous to be drinking too much water...your kidneys get overloaded and don't work as fast and swells your brain. I don't think 5.1 litres is healthy...

*pokes head in*

Here we go again!

You need the equivalent of 8 cups of water a day on average, from any source. These sources can be pure water/tea/coffee/juice/soda/milk/fruit/veg etc. It does NOT have to be pure neat water!

As for coffee being a diuretic, so many people just spout that word as a reason, without actually understanding what "diuretic" means.

di·u·ret·ic (d-rtk)
adj.
Tending to increase the discharge of urine.
n.
A substance or drug that tends to increase the discharge of urine.

Neat water is also a diuretic. The diuretic effect of caffeine is far, far outweighed by the actual water in the tea/coffee. Also, regular consumers of caffeinated beverages will build up a tolerance to said effect, eventually reaching the point where caffeinated drinks provide practically the same amount of hydration as a cup of neat water will.

*leaves*

I tend to drink about 4 liters a day. I usually never let myself get thirty because once you feel thirst you are already dehydrated. I've drank anywhere from 1 to 4.5 liters a day.
