A company down in Florida makes these AWGs, Atmospheric Water Generators, that provide pure clean water from the humidity in the air. They come in sizes from producing 8 gallons daily to 1000s of gallons daily. I think they can even be designed to run on solar power.
FEMA should consider purchasing at least one unit to see how it easily it can be transported and set up for operation whenever and wherever the water source has been compromised.
