Water Disruption
It's unsettling to turn on the tap and not trust it. The good news: clean water is easy to manage once you know the steps. Here's what to drink, what to skip, and how to keep enough on hand.
During an advisory, water from your tap can carry bacteria or parasites even though it looks and smells fine. That makes it risky not just for drinking, but for brushing teeth, rinsing produce, or washing a cut. The safe move is to treat every drop that touches your mouth or an open wound as off-limits until it's boiled or bottled. Everything else follows from that one rule.
Once you start counting, water disappears quicker than people expect. Drinking, cooking, coffee, brushing teeth, washing hands, the pets — it adds up to roughly a gallon per person per day just for the basics. A household of four needs about four gallons a day, and that's before cleaning. Filling containers early, while the pressure's still good, is the difference between comfortable and scrambling.
It's easy to forget that the ice maker and the filtered water in your fridge door run off the same tap that's under advisory. That built-in filter removes grit and chlorine taste — it does not kill bacteria. So skip the door water and dump any ice the machine made after the advisory started. Make new ice only from boiled or bottled water.
Anything that normally uses tap water gets a second thought: washing dishes, rinsing produce, cooking pasta, scrubbing hands. You can still wash dishes with a sanitizing rinse or a hot dishwasher cycle, but it is slower. Paper plates and hand sanitizer take a lot of pressure off your water supply while the advisory lasts.
You can do every one of these right now, with what's already in your home.

Babies on formula. Mix formula only with bottled water, or tap water you've boiled and cooled — never straight from the tap during an advisory. If you can, switch to ready-to-feed formula, which needs no water at all. Sterilize bottles with boiled water too, and when in doubt, ask your pediatrician's office; they field this question constantly.
Dialysis patients. This one matters: people on home dialysis cannot use boiled water — boiling kills germs but concentrates minerals and contaminants, which is dangerous for them. They need bottled or specially treated water, so call the dialysis center right away for instructions. Don't improvise this one.
Anyone immunocompromised. People on chemo, with HIV, or after a transplant can get seriously ill from bugs that barely bother a healthy person. They should stick strictly to bottled or boiled water for anything that touches the mouth, and be careful with shower water on broken skin. When the advisory is flood-related, lean toward bottled water to be safe.
Anyone with an open wound. Tap water under advisory can introduce bacteria into a cut or scrape, so clean wounds with bottled or boiled-and-cooled water only. Keep the dressing dry, and if a wound looks red, warm, or swollen, treat that as a reason to call a doctor. It is a small thing that is easy to overlook in the shuffle.
Pool water carries algaecides and concentrated chemicals that boiling won't remove. It's fine for flushing toilets — that's its emergency job.
The fridge dispenser and ice maker draw from the same compromised supply. Skip both until the all-clear, then flush and swap the filter — per CDC guidance.
Toilets flush fine with pool water, rain barrel water, or the murky stuff. Save the clean water for people.
The moment a disruption looks likely, fill the bathtub, pots, and every clean container. Water you caught early is water you don't have to find later.
A good filter and a way to store water turn a stressful advisory into a minor inconvenience.

Built for flood zones and virus-risk areas
Why we chose it
When flooding mixes sewage into the water supply, a standard 0.1-micron filter isn't enough. The LifeStraw Family filters down to 0.02 microns — fine enough to remove viruses too, not just bacteria and protozoa. It's one of the few portable purifiers that does, which is why we reach for it when the water could carry sewage.

Adults and older kids can usually shower as long as they don't swallow the water — keep your mouth closed and don't shave over fresh cuts. For babies and toddlers who might gulp bathwater, sponge-bathe them with boiled-and-cooled or bottled water instead. Keep open wounds out of the tap water.
Use bottled water, or tap water you've boiled for one minute and let cool to a safe temperature. The easiest option is ready-to-feed formula, which needs no water at all. Sterilize bottles and nipples with boiled water too, and ask your pediatrician if you're unsure.
Toss any ice the machine made after the advisory started — freezing doesn't kill bacteria, it just pauses them. Turn the ice maker off for now, and make new ice only from boiled or bottled water. Then you're fine.
A rolling boil for one full minute kills the germs that matter. If you live above about 6,500 feet, make it three minutes, since water boils at a lower temperature up high. Then let it cool on its own — don't add tap water or ice to speed it up.
Not during the advisory. Even though you spit it out, enough gets swallowed to make you sick. Brush with bottled or boiled water, and rinse your toothbrush in safe water too. It feels fussy, but it's the same risk as drinking it.
Yes, with a little care. A hot dishwasher cycle with a heated dry is fine. For hand-washing, wash as usual, then dip dishes in a sanitizing rinse — about a teaspoon of unscented bleach per gallon of water — and let them air-dry. Or just use paper plates until it lifts.
Give them the same safe water you are drinking — boiled or bottled. The same bugs that make people sick can make animals sick too. It is one more reason to fill extra containers early.
Almost. Once the utility gives the all-clear, run your cold taps for a few minutes to flush the lines, run the dishwasher empty once, and replace any water-filter cartridges. Drain and refill the ice maker. After that quick flush, you are back to normal.
The calmest households aren't the most worried ones — they just have a plan. Once this passes, a few quiet minutes now saves a lot of stress next time.
