In my part of saving the world i would produce my own water in to ways, well an a more natural way boiling sap. most people got a home well so do i but in the spring i boil sap to make maple syrup an all the steam thats released touches a cold pice of tin condenses turns to clean distilled water in which collects into a bucket an there i have done 2 good things at once. which a lot of people that boil a lot of syrup do this same thing
