Those containers are fairly nice but quite expensive, more expensive per gallon EMPTY in fact than buying 1 gal. bottled water bottles FULL. I'm not too concerned about ruggedness since my bottles are in the cabinet under the kitchen sink, not getting bumped around. Also not concerned about opacity since it's dark in the cabinet. If I wanted to store more water I think I'd get a 60 or 110 gallon Aquaflex bladder (
www.aquaflex.net ) and put it under my bed. I'm in a small apartment and don't have space for 55 gal drums, stacks of 7-gal Aqua-tainers, etc.
One thing I ought to do is carefully scrub out the inside of my toilet tank the next time I scrub the toilet. There's at least 5 gal of fresh water there that gets "rotated out" several times a day. I wouldn't drink toilet bowl water even after treatment unless I absolutely had to (psychological reasons; pets drink the stuff all the time with no obvious ill effects) but water from the tank doesn't have that issue. Just the same, because it's in contact with the funky old fixture and flush mechanism and standpipe, I'd use it for non-drinking or last-resort drinking purposes and would treat it before drinking.
Finally, I have a typical 13 gal. PVC kitchen wastebasket and a few 8 gal wastebaskets around the apartment, so of course if there was a warning of upcoming disaster, I'd fill those with water, plus fill the bathtub. But that doesn't help in a no-warning event.
Sorry, didn't mean to hijack the thread with this. Further wish-list item: an auto cigarette lighter plug with the right connector to operate my Eveready CH15 NiMH charger in the car, so I can charge up my AA NiMH batteries in extended power outages. It's a 15 minute charger with 12 volt input, so it's just the right setup for in-car use. I don't understand why it doesn't come with a cig lighter plug.
