Supplies
Track your water
Log bottles, jugs, and barrels in any unit and get one clean total in gallons.
Last updated July 4, 2026
Water is the supply you'll miss first, and the one most people undercount. Provision Planner does the unit math for you so you always know exactly how much you have.

Everything converts to gallons
Enter each container in whatever unit is on the label: fluid ounces for bottled water, quarts, liters, or gallons for jugs and barrels. The app converts every entry and keeps a running total in gallons at the top of the table (for example, 4 quarts = 1 gallon).
How your water duration is calculated
Your dashboard's Water duration takes your total stored gallons and divides it across your household: every person gets their daily amount (1 gallon per person per day by default), and pets get theirs if you've set it. You can adjust both in household settings.
Note
The 1 gallon per person per day default is a common emergency-planning baseline that covers drinking and basic hygiene. Hot climates, pregnant women, and people who are ill may need more.
Tips for logging water
- Count the whole case. A 40-count case of 16.9 oz bottles is about 5.3 gallons. Log the case once with quantity and volume, and the app handles the math.
- Don't forget utility water. Water for washing and cooking counts too. If you store it, log it.
- Rotate your stock. Store-bought bottled water keeps a long time, but filled containers should be refreshed periodically. Add an expiration date to any container so it shows up when you review what's aging. See Expiration dates.
