Every half hour I get thirsty, reach for the ever present bottle of water and take a few healthy gulps. Forty-eight drinks of water each day, times 365 = 180 gallons a year. Meanwhile, a couple billion other people are unable to practice this basic ritual.

Have you ever caught and tasted rainwater? I don’t know why, but every time the rain comes I set up a primitive catchment system and start drinking rainwater. It’s an elixir. In a single storm I extend my cup and receive more than I could drink in a lifetime. Uncountable gallons of fresh drinking water are bestowed upon us daily.

Over the past few years, while catching and drinking rainwater, I have figured out how the increasing billions who go thirsty can also catch, store and enjoy clean drinking water year 'round.
