perfect storage

[Lightspeed]

Water:

Be sure to us food grade containers, and if second hand be certain what was in them before you got them.

Keep plastic containers away from direct contact with concrete floors

Remember water is bloody heavy. A one meter cube of it weighs literally a ton. So don't be tempted to store lads of it in the loft.

Of course as NR said dehydrated water is the answer as its much lighter and folds down to easily concealed packets.
