You could use a pump setup to avoid driving around the house with a forktruck. Buy the 500gal tank & keep it in the cellar. Then get a well pump & pressure tank. The well pump will pump water from the storage tank ( it won't know that it is not hooked up to a well, unless you tell it!) into the pressure tank. You just have to have a check valve between your place & street water, & a valve to connect the pressure tank to your house piping. A generator to run your pump, furnace & refrigerator is not a bad idea, either. I have a friend with this setup & it works fine.
