I agree with you on the fire extinguishers. I did mention them, but it was just in passing, with the battery-powered smoke/CO detectors.<br><br>I've got you beat on the water- 4 55-gallon drums, 2 15-gallon drums (with nice handles that are a sick joke, at that weight), and 3 5-gallon bottles, not counting the contents of the water heater. Ok, I’m paranoid. That goes without saying. I’m HERE, aren’t I? :-)<br><br>As for sanitation, if you’re even more paranoid than I am, you might consider a check or gate valve on the sewer line from the house, if you’re not on a septic system. If the sewage treatment plants ever fail, I can’t think of anything that would ruin your preparations and force you to become a refugee faster than sewage backing into the house. Unfortunately, check valves tend to be iffy, you probably won’t know until too late if it ever closes, and gate valves require forewarning and a conscious decision to close. From experience with local governments, I consider forewarning unlikely.<br><br>For primitive sanitation, may I recommend that you check out “The Humanure Handbook”, subtitled “A Guide to Composting Human Manure, Emphasizing Minimum Technology and Maximum Hygienic Safety”, by J.C. Jenkins? I found it a very entertaining, even fascinating read, and unless the guy is just lying about his results, it would seem to be a breakthrough in primitive sanitation.<br><br>All that having been said, I’m a bit cynical on the issue. By the time sanitation becomes a serious problem, I suspect that FEMA and/or the National Guard will impose “forced evacuations” (for our own good, of course). They won’t care how well we've prepared or what we have to lose, and they won’t take “no” for an answer- forcing us to become refugees and separating us from 95 percent of our resources anyway.<br>
