My long-term water storage is comprised of 5 Litre casks - mylar bags encased in cardboard, an Australian brand "Noble's" - about as pure as pure water gets, and probably good for decades as long as the bag remains sealed. These are easy to transport (around 5.1kg), easy to stack, and offer the bonus of a useful mylar bag or emergency pillow once drained.Jeriah wrote: I don't see the point of buying bottled water, then breaking the seal, which means you have to add bleach, which makes it taste worse than tap water. Why not just rotate your stock of bottled water occasionally? Most of us could stand to drink more water anyway.
We keep 1 in the boot of each vehicle, and rotate those every six months as it gets pretty hot here. I currently have 16 of them stored in the house (still rebuilding supplies lost in the deluge), along with around 20 litres in individual plastic bottles that are rotated far more frequently.
