Milk jugs are not good to save and use as water storage containers. Gallon jugs that water comes in from stores tend to degrade after awhile and spring leaks. I got trash cans and then lined them with food grade plastic liners. You can get food grade plastic barrels but remember to get a pump to get the water out.
Good hint if you are looking for a shower...get a NEW bug spray canister with the pump handle works great as a shower I have a black metal one that can be sat out in the sun so the water can be solar heated.
Thanks for the bug-sprayer shower idea!!! How to get REALLY clean using a minimum of water. Brilliant!
