I am talking a 30 day period , I buy water by the case,it has three one gallon jugs for a couple bucks a case, that gives me a gallon a day for 30 days. I rotate them out as we use them. For longer term  usage ,I have several rain barrels to draw from . A decant filter , hydrogen peroxide ,bleach and iodine  I keep  on hand for  purification. this is also  pretty neat way to purify  water.

I think having water available without having to travel is neccasary.
List your water filters or plan for 30 days.
Thanks
Ron
