72-Hour Storage Targets 30-Day & 90-Day Plans Container Planning Guide Hygiene Breakdowns Instant PDF Download

Do you actually know how much water your family would need to survive 72 hours — or even 30 days — without running water?

Most families know water storage is important, but very few know how much they actually need. Too little leaves your family at risk. Too much means wasted money and space. Guessing isn't a plan.

This worksheet does the calculation for you — enter your household details, and your real water targets appear instantly.

From 72-hour emergency coverage through to a full 90-day supply, every storage goal is broken down clearly — including drinking water, cooking water, hygiene, and container planning guidance.

No confusing math. No guessing. No overbuying. Just a clear, organised plan your family can actually act on.
