Absolutely. I guess I figured that was implied in my post - 28 gallons or 53 2 liter bottles. I keep about 8 under my dining table but I have plenty available in containers - about 150 gallons - plus the well with solar power for the pump. I get careless about refreshing those 2 liter bottles. If you do store them for any extended period probably a couple of drops of bleach in each would be indicated.
I’ve got 12 gallons of water stored in the basement, but hubby installed a hand pump on our well that he got from Lehman’s catalog many years ago (they have mainly non-electric items). They have a large store in Ohio and are a great place to visit.
