"You can survive 3 weeks without food. You cannot survive 3 days without water." — Every survival manual ever written
Water is not optional. It is not a nice-to-have. Every single survival plan begins and ends with clean water. Before you buy freeze-dried food, before you buy a generator, before you do anything else — you need water sorted. This section covers storage, purification, sourcing, and long-term planning.
Begin with the grid-down water storage checklist, then plan treatment and longer-term capacity.

⚛ CIVIL DEFENSE ADVISORY
Fill every bathtub, pot, pitcher, and clean container immediately when a crisis is announced. Municipal water pressure typically drops within 24-48 hours of a grid failure. A WaterBOB in your tub can hold 100 gallons in 20 minutes. That's 50 days of drinking water for two people.
