Good article Burt. You don't have to be all that creative to find solutions to the water problem.  Many of us have 5 gal. drink coolers for picnics which can be packed with survival food and supplies for space savings and after we remove the survival food, they can be filled with clean water for drinking before the storm hits.  All homes have trash bins outdoors and many are plastic.  After transfering the trash to a plastic bag they can be rinsed and filled in advance of a storm with water to be used for flushing toilets along with a 2 gal. bucket. Pee can be left to stink but solids do need to be flushed.   Your water heater is a good source of clean water as well and shutting off its inlet will protect it from contamination. The gas or electricity to it should be shut off to avoid burning it up. Panic buying of stocks of bottled water is unnecessary and creates waste.
