I live in the high desert, which means water is limited when the grid goes down. In the winter we usually get snow and rain (although the last two years this has not happened. I have my theories). Right now we are having to re-roof our home which covers a 3,000 sq. ft area. So, while we are doing that we are adding rain gutters in which we will capture and use our rain water for whatever purpose is needed during SHTF. I have 10- 55 gallon drums on one side of my house that are always filled with clean water. I take any empty miscellaneous bottles we get from store bought items and fill those with reverse osmosis water and store them in a 26′ container out back, and have done this for about 7 yrs now. On occasion I will get a case of bottle water and store it away. I have a Berkey unit for when the grid goes down and my RO unit can no longer be useful. Other than that, we are SOL. I’ll just pray for rain.
