DOC-103 Water 4 min

Water Plan

One gallon per person per day is the baseline. Store more if heat, illness, pets, or cooking demand it.

TL;DR

Store at least 3 days of water; aim for 2 weeks at home if space allows.

Stored water comes first; field treatment is the backup layer.

How this plan fails

Water with fuel, toxic chemicals, or flood contamination may not be made safe by normal household treatment. Follow local health authority instructions.

Do not spend your first mistake here

  • Drinking from radiators, boilers, or chemically contaminated sources.
  • Waiting until the tap is dry to fill containers.

Water is where preparedness becomes arithmetic.

For four people, the 3-day minimum is 12 gallons. A 2-week target is 56 gallons. That number feels large because it is honest. Store it in layers: cases of bottled water, larger food-grade containers, and a plan to fill tubs or pots when a storm, grid failure, or water-main break is likely.

Do not make the plan depend on one device. A filter is useful. Stored water is better. Boiling is useful when fuel and a safe heat source exist. Local boil-water notices and health-department instructions outrank generic internet advice.

In the first hour of a grid or water emergency, fill containers while pressure remains.
