Global Water: 

Global Water Ocean (Salty) 97.2 % Fresh Water 2.8 % Ice 2.15% Liquid 0.65% Groundwater 0.62% Lakes 0.009% Soil Moisture 0.005% Streams and Rivers 0.001% Atmosphere 0.0001%

Why Not Use Sea Water?: 

Why Not Use Sea Water? Desalination now provides 1% of world drinking water Distillation (Energy intensive) Passive distillation (Slow, inefficient) Reverse Osmosis (Filters delicate, prone to clogging and contamination) Towing Antarctic Icebergs (Not done yet, but the numbers are promising)
