I have a PDF file that goes into detail on filtering urine in a homemade way. Very simple. I will try to find it online.. if not I will copy/paste the details here if anyone is interested.

Sounds gross, but lets face it, if you really believe there is going to be some situation where you can't get water for a long period of time, drinking pee is preferable to death.
