Iowa One Call

Did you know that 811 only marks public utility lines? That means water, gas, sewer, and telecom lines running from the street to your home or business are covered—but privately installed lines are not.

Private lines may include:
- Underground sprinkler systems
- Propane or private gas lines
- Landscape lighting wiring
- Invisible pet fences

If you’re digging near private utilities, you’ll need to hire a private utility locator to ensure everything is marked before you break ground. Taking this extra step helps prevent costly damage and ensures a safer worksite.

From understanding the marking process to knowing when to file your underground locate request, you'll find everything you need to know to dig safely.

Memorial Day (May 26) will not count towards your standard notice required when filing a locate request, so please plan accordingly.

Did you know? The soil beneath your feet holds a wealth of resources. For example, there are over 20 million miles of underground infrastructure in the U.S. alone!

Stay informed and dig with confidence.
