Long Term Water Storage

I've been interested in storing water in my home incase of an emergency.  

You see, if our electricity goes out, so does the pump to our well.  If the pump in the well goes out, no water. If the wires to the well go bad - no water (just ask my neighbor). If we have a serious earthquake the well could be permanently damaged. This means no flushing toilets, no washing dishes, you get the idea.

We are NOT on city water.  

I've looked at several types of containers such as the 55 gallon drum, aqua paks, and these water bricks.  

55 gallon drum 

 Impossible to move once it is filled with water

Difficult to store several in our small mechanical room

Awkward shape

huge mess if it spills

But it would have some water pressure if we used the attachable hose

$50 at Smithfield Implement 

aqua pak

7.5 gallon size or 5 gallon size would be easier to carry

Easier to rotate the water supply

you can only stack them 2 high or they will split

$13.95 for 5 gallon at beprepared.com

water brick

heavy duty and bpa free

can also be used to store grains and legumes

3.5 gallon - even I could carry that and rotate the water supplied in them

stack them 10 feet up and they hold up  - you can even make a house out of them - I thought you'd get a laugh out of that one

small enough to stick anywhere

I don't have to store them all in the mechanical room - I can put a couple under the sink in each bathroom.

$16.95 at Shelf Reliance

Check it out - it even comes in CAMO - perfect for camping and we love camping!

What have you used in the past to store water?  I could store water in soda bottle - but we really don't drink that much soda.  And they don't stack. 

So what do you think of these bricks?  Have you seen any other great ideas you could share with me? The price makes my heart skip a beat but I think that maybe it means they will last longer, they are made with a more environmentally friendly material, and well, they use space efficiently. Am I jumping the gun here? Or do these really make sense?
