Expert Boil Water Notice for Twin Cities Homeowners

When the City Says Boil Your Water

A boil water notice means treating the tap as unsafe to drink until further notice. In the Twin Cities they usually follow a main break, a drop in system pressure, or a routine sample that came back positive.

It is precautionary: the utility cannot currently guarantee the water is safe, which is not the same as confirming it is not. The instructions your utility publishes with the notice take precedence over anything on this page.

Boil at a full rolling boil for one minute and let it cool on its own. Do not rely on a household filter, which is built for taste and sediment rather than bacteria.

Once it lifts, flush the cold taps, dump the ice, replace filter cartridges and run the dishwasher empty on hot. We can flush the system, swap the filters and test the water if you would rather not guess.

Signs You Need This Service

Don't wait for a failure. Watch for these critical warning signs that your plumbing system is struggling.

Your city issued a notice

Follow the utility's own instructions first. They know what triggered it.

There was a water main break

The most common trigger, because pressure loss can let contamination in.

Water pressure dropped suddenly

A pressure loss event is what makes a utility cautious enough to advise boiling.

The water looks cloudy or discoloured

Worth reporting, and worth not drinking until you have an answer.

The notice has just lifted

Flushing, ice, filters and the dishwasher all need attention before you relax.

You would rather see a test

Particularly with a baby in the house or a well near an affected main.

Frequently Asked Questions

What is a boil water notice? +
It is an advisory from your city or water utility telling residents to boil tap water before drinking it. They are usually issued after a water main break, a loss of system pressure, or a routine test that comes back positive for bacteria. It is a precaution, and it is issued because the utility cannot be certain the water is safe, not necessarily because contamination has been confirmed.
How long do I need to boil the water? +
Bring it to a full rolling boil for one minute, then let it cool on its own. That is the guidance for our elevation. Do not add ice to cool it faster, since the ice was made with the same water. Always follow the specific instructions your utility publishes with the notice, because they know what triggered it.
What do I need to use boiled or bottled water for? +
Drinking, cooking, making ice, brushing teeth, rinsing produce, and filling pet bowls. Washing hands is generally fine, and most adults can shower or bathe as long as they avoid swallowing water. Take extra care with infants and anyone with a compromised immune system, and follow your utility's advice.
Will my water filter make it safe? +
Assume it will not. Most household filters are built to improve taste, odour and sediment, not to remove bacteria, and a filter cartridge that was in place during the event may now be contaminated itself. Boiling is the reliable step. Replace the cartridge once the notice is lifted.
What should I do after the notice is lifted? +
Run your cold taps for about five minutes to clear the lines, dump any ice made during the notice and run a cycle or two through the ice maker, replace filter cartridges, and run the dishwasher empty on a hot cycle. If you would rather have confirmation than take it on faith, we can test your water.
