I recently had my submersable well water pump go bad on me. Not enough funds to have it replaced commercially so I opted to do it myself. It took me 1 week to DIY and had to rely on the 5 gallon containers of water I have had stored in my basement. Why did it take me so long? had to wait for a frient to come over and help. 2 hours for my wife, friend and I to pull it and replace. 2 hours prep time for me to get everything ready.
10 five gallon containers lasted me 7 days. Most of it was used to flush the toilet. Purchased water was used for drinking and cooking.
Some melted snow water was used also for flushing. Wood burner in living room did good

I have a ss rectangular deep pan that holds 3.5 gallons of water on the wood burner at all time for adding moisture to the air. Melts snow really nice.
It's good to have emergency supplies on hand. Never know when you'll need your supplies.
You city folk have needs for emergency supplies also.

A major snow storm can wipe out the grocery store shelves in 3 days or less.
