If you want a tough water container, get these , the current USGI water container. Made in Canada (go figure), they are shaped like a regular jeep can, made of super heavy duty plastic. I have a five gal, and a 2.5 gal., they have been all over the western US, Canada, and Alaska, and have yet to spring a leak. One is hung on the back of our RV, no apparent effect by UV. You can get them at Brigade QM and other "military surplus" dealers...
