One of the things I've been pondering is how to do water storage for a short term bug in situation. None of the options I saw really impressed me, until I went to fix a plumbing problem. My house used to have one of those huge old fashioned water softeners that took 50 lbs bags of salt. The previous owner took it out and now there is just a big hole that has the incoming water pipes running into it. I was about to fill this in, when I realized it was about the right size for a 55 gallon drum. My idea is to take a close top poly drum like this Luckily I can get as many of these as I want for free. and plumb it in that old hole. One bung will have the incoming water from the city supply, the other will hook up to the line going into the house. the water will be constantly circulated in the drum. When the water system goes down all I have to do is turn off the water supply in the alley, and use either the electric pumps I have, both 110 or 12 volt, or a manual rotary pump to get the water out. any comments, reasons why this won't work?
