Why Does Water Always Come to the Surface?

When we have a leak, water always comes to the surface. By the time you get to the centre of the earth, the pressure is absolutely enormous. In fact, in the great artesian basin that's about half a kilmeter down, water comes out at a very high pressure. And so we're using up that water, which has taken millions of years to put there. Goodness, te otso piciclly.
