Partners & Jurisdictions

NotifyJoCo is brought to you by a partnership among the County, WaterOne, and participating cities. Check out the Partners page to see if your city is participating.

All cities in Johnson County are welcome to become a full partner in this unprecedented collaboration of local governments. If you're interested in having your city of residence participate, contact your city officials today.

If I don't reside in a participating city, can I still get NotifyJoCo alerts?

Yes. All registered residents, no matter which city you reside in, will receive county-wide emergency alerts. So will WaterOne customers. However, if you live in a city that is not yet participating in NotifyJoCo, you will not receive local city-wide alerts or non-emergency alerts from NotifyJoCo.

Do you live in another county but work or spend time in Johnson County? You can register your alert locations to receive alerts that matter to you.

Customize your contact information and preferences to ensure WaterOne and/or the County can reach you during an emergency. Check to see if your city offers a similar notification service or encourage them to become a participating partner in NotifyJoCo.
