Clearly a generator could power the wells but I may not want to draw attention to myself with the noise of a generator...
I'm not sure there's much need for a 50 gallon water heater-type storage inside the house.
Thanks, but that is 500 gallons, outside and portable (In an old Jeep trailer).
My goal is simple: Daily use, optimized for potential disaster, like earthquake, fire, drought. If I can muster 15000 gallons above ground, with 10000 gallons high enough to provide gravity flow (though a lousy shower) AND 500 gallon of refreshed water that is portable, I will have made significant progress toward meeting long term "off-the-grid" water needs. This will take my family through initial and prolonged recovery efforts AND permit our escape (if necessary) to a better location.
