A friend of mine (suburbs of Atlanta) had kinda decided to drill a water well to aid in his family’s survival when TSHTF.
I asked him “how will you draw water when the electricity goes out?
How will you get fuel for your generator?
How will you defend your home and your generator and your fuel supply from the marauders and barbarians that are 72 - 120 hours away?”
He clearly had not thought out the reality of the dark future.
LOL. The same way my grandparents did before electrcity from cisterns or wells. With a weighted water tube and rope. No electricity for pump? No problem. Remove the sanitary seal from the casing and lower a tube to water. My well is 180 ft and cased to 60 plus. Good safe water under almost and circumstance. Not even the heaviest of rains turns it dingie in the least. A good sign of no surface contamination.
In a pinch I also have two good springs and one is safe one would require purification due to neighbors cattle. Also around the house keep bleach. It will do for purification purposes in a pinch. It doesn't take much at all a few drops to a gallon IIRC.
