Beneath Ohio’s streets and fields lie thousands of miles of buried utilities.

The water flowing to your faucet, the energy that warms our homes, the connections that keep us linked.

Safety isn’t just a rule; it’s Ohio law and our shared responsibility to protect our communities and the vital resources that keep our state running. Together, we keep Ohio safe and help protect what matters.

Did you know that burying utilities in Ohio started in the 1800s?

With the extensive volume of underground utility infrastructure, never guess depth. Erosion, weather, and time can change everything!

– Always Call Before You Dig!
