Your starting point

Build the water plan your household actually needs.

You do not need to solve every water problem at once. Pick the situation closest to yours, complete the first two guides, and add the next layer when you are ready.

The simplest reliable order

Store known-safe drinking water first. Next, prepare for the most likely interruption in your home. Then add treatment and longer-duration backup options. A filter or water-producing system should supplement—not replace—a stored supply.

Build the first seven days

Not sure which path fits?

Begin with stored water.

A seven-day supply supports every other strategy and still works when power, equipment, fuel, weather, or a treatment device does not.
