The original thread is for a go bag, or bug out bag, not a pantry or vehicle storage. So keep that in mind when making suggestions.

you can store as much water as you like wherever you want, but how much are you going to put in your bag?? At 8.35 lbs per gallon, how much can you carry with you?

Like I said before, leave your bug out bag empty of so called "emergency water" have water carrying capacity to fill up when you have to move,
keep a gallon in the car if you like to fill the containers on the bag if you have to leave the vehicle.
If you are leaving from the house, I would hope you have some water stored to fill up and get going.

as for storing water in large quantities, not practical - and thats just the fact of the matter. If you were to base your system on accumulating water instead of the capability to purify found water, you won't get very far.

If the water resources are that contaminated that filtration doesn't work, then we are all screwed anyways, so keep stock piling if you like and prolong the inevitable.

As for filters breaking - follow the typiical rule, 1 is none, 2 is one and so on.

I'm not even going to touch on the emergency food bars issue with you - When you look up the calores in one LRP meal and compare that to how many food bars you have to consume to replenish what you used in a day, and just to get you on track, one LRP meal contains enough calories for an avg male to patrol all day, so 6000+
