ironraven - I guess what you're really trying to do is retort-package your own water. By the way, I suppose it is possible to home can your own water, if you wanted to (glass jars?!?)

I would get some food grade plastic bags, possibly with an aluminum "oxygen barrier" layer, fill partway with tap water leaving some space, squeeze out all the air and then heat seal. Boil in a water bath or even a pressure cooker. Now everything inside is dead.

Now, how do you set an expiration date?
