I solve the water storage problem (not for hurricanes, but anything/everything else) is to pump water from the well directly into large water storage tanks (800 to I think 1500 gallons), then use a pressure tank and small pump into the house. One is set up for gravity feed.
Even someone not on a well could purchase a large tank or two and have in the back yard or good sized garage. Lots of water even if no electricity is real peace of mind.
We’re looking into a solar well pump since it’s a bit too deep for a hand pump.
If I were going to drink water from a 1,500 gallon storage tank as you do, I am sure I would want to treat it in some way before drinking. Just not comfortable with the chlorine. There are other options available.
How long do you store this water before use?
