I ran across these large capacity water storage tanks mentioned on the Utah Preppers website. They are made to be easily drained, cleaned, and refilled. The website doesn’t mention that they are BPA-free but I checked with the company and sure enough… they are. Their largest tank is priced at about $1 per gallon. Seems like a bargain to me.
I just ran across what seems like the best place to buy long-term food storage containers. I’ve not ordered from them yet though, so this is not a product endorsement of any kind (yet).
The sell BPA-free gamma lids and the prices are really low, at least lower than I’ve seen elsewhere. They also stock mylar bags, heat sealers, 5-gallon buckets, oxygen absorbers, rainwater collection barrels, and water storage tanks too. I kind of suspect many other preparedness retailers get their stuff wholesale from a place like this. Luckily they also sell direct to the public in small quantities.
