EPA: 23 Million American Homes Can Lose Running Water When the Power Goes Out — And the Overlooked Reason Why

Most people assume the tap keeps working no matter what. Often it does, for a while.

But every gallon that reaches your faucet got there with electricity.

And backup power doesn't last forever.

Here's how it usually plays out:

• Right away: well pumps stop. On a private well, no power means no water.
• First hours: backup kicks in. In town, treatment plants and pumping stations switch to generators, and water towers hold pressure for a while.
• Days 1 to 3: pressure can drop. In a long outage, a hard freeze or a flood, pressure falls. That's when cities tell people to boil their water.
• Week 1 and beyond: repairs take time. After big storms, fixing a water system can take weeks. Ready.gov asks every family to be ready for at least 3 days on their own.

You figure the cases in the garage have you covered. Run the numbers.

Ready.gov says one gallon per person, per day, for drinking and basic hygiene. A family of four goes through 4 gallons every day.

12 gallons stored = 3 days.
56 gallons stored = 2 weeks.

And this isn't a what-if. It has happened more than once.

Texas, February 2021: a winter storm took out the power, and millions of Texans were told to boil their tap water. Some waited more than a week.

Hurricane Helene, 2024: floods broke Asheville's water system, and parts of the city went weeks without running water.

One was a cold snap. The other was rain.

Stored water only goes one way: down. When it runs out, you need a way to get more.

Storing water is a good start. It isn't the whole plan.

Most homes are closer to water than they think: a rain barrel, a creek or pond down the road, the tank inside the water heater.

The catch is what's in it.

• Sediment and grit: sand, silt and rust that cloud the water.
• Leaves and debris: the bits you can see floating in a barrel or a creek.
• Bad taste and odor: stale, earthy water nobody wants to drink.
• Germs: untreated water can carry bacteria and parasites.

So prepared families stopped asking "how much water can I store?" and started asking "how do I refill when it runs out?"

Here's what they keep in the closet.

The Family Ready 6L Gravity Water System filters water for the whole family at once. It needs no power, no pumping, and no sucking on a straw.

Fill the 6-liter bag. Hang it from a hook, a door frame or a branch. Gravity pulls the water through the filter while you get on with everything else, and filtered water runs out the end, hands-free.

Its 4-layer filter is built around two parts:

• A 0.1-micron hollow-fiber membrane. The core: thousands of tiny hollow fibers with pores far finer than a human hair.
• Coconut carbon. Helps clear bad taste and odor, even from cloudy river water.

It holds 1.6 gallons per fill, where most gravity kits hold 1.

Water goes in the top. Filtered water comes out the bottom. Every time.
