I have a water source 2 blocks away. I think if it ever got to that point I would already be out of here. That was one of the main requirements when I was scouting locations if I had to leave. I found an underground spring that runs year round.

I keep lots of calcium hipochlorite on hand. I also have a large supply of coffee filters and a couple of .5 micron filters.I keep a 15gal and 2 5 gal water jugs ready to go.

The good thing is that we are on a water tower so I would have a little time to fill the containers. I dry camp allot and the trailer has a 50gal tank. being careful but still washing the dishes and taking some showers I still had a 1/4 tank after 2 weeks once.
