I store enough for about a week. But the truth is, if I lose water where I live (Washington, D.C.), I'd be leaving the city within a couple days (well, probably a couple hours). Have a place to go that's on a tributary to the Chesapeake Bay and which has well water, a backup generator and two very large propane tanks that would power everything, including the a/c, for a couple weeks.

If I can't get to that place in an emergency it will be Mad Max for real on the east coast.
