RE: Water collection options
Everyone should also look at the technology of the slow sand filter as SD was referencing.
They take no special equipment, just the knowledge of how to build one, and they take over after the commercial filters have degraded.
Living alone with very light filtering necessary, my commercial filters will last me until I die! 10 years or more. Even a simple Sawyer Squeeze with filter 100,000 gallons! Unless you are filtering your bath water that should last a few years, not a few days.
