Somehow the discussion just got shifted from two weeks to indefinite. 
Getting back to the two weeks discussion one method that I use is to
fill 3 gallon jugs at one of the "water store" places for 25 cents per
gallon.  The water is filtered and treated and I think tastes better. 
Then I just place the 3 gallon jugs up into a dispenser and I have water
which I drink everyday.  Rotate through the jugs (1 have 8 or 9) and do
not let more than 5 get empty and you will have at least 15 gallons of
fresh water which will give you a gallon a day for two weeks.

And there is water in the average home water system pipes and water heater.

Of course this discussion needs an explicit threat model to be more
complete.  Considering how to survive for two weeks after a major quake
with no tsunami is different from a major quake with a tsunami is
different from a huge volcanic eruption resulting in major global crop
failure is different from economic collapse. 

And there are companies provide related items.  One company is

I have purchased Gamma Seal lids from them for sealing 5 gallon
buckets.  I wanted to have some storage at Burning Man which would keep
playa dust out and in one bucket keep garbage odors in.  The Gamma Seal
lids worked perfectly.
