They have a nice rubber seal on the lids, so they stay dry dry dry inside even if the crawlspace is a little damp.

The barrels (not all shown) contain my long term storage items. So the standards, rice and beans, hundreds of bags of my homemade MRE's, canned goods, paper products (TP, PT, PP), pasta, flour, sugar, etc etc etc. you know everything that any of us put up.

Most of my water is in the form of 5 gallon bottles, and in a different location. but I don't store much in that manner, as I have 165 000 gallons in my pond (potable) 20 feet from my backdoor, and a creek 1/4 mile away. I do have one barrel filled with 500ml bottles, that we rotate out through my pepsi machine each summer.
