Answer 2

Well you aren't specific enough. Do you mean purified through the natural water cycle or through water treatment plants?

Here's info on the water cycle:

I included some diagrams as well that should help you model a 3D representation. Each of these sites will go through the steps in each method. All you have to do is read.
