Call Before You Dig

A pipline inspector at a construction site​Call 811 before you dig. Minnesota law requires anyone excavating to notify Gopher State One Call at least two days before beginning a project so utility companies can mark the approximate location of potentially hazardous underground facilities.

Digging without knowing the location of underground utilities increases the likelihood of unintentional damage, which can cause serious injuries, service disruptions and repair costs. Call 811 first so you don’t have to call 911 later. 

Or go online to www.gopherstateonecall.org and request underground utilities near the area you’re digging be marked. 

Find Out Where the Pipes Are

​Many of us go about our everyday lives completely oblivious to the miles of infrastructure located in the ground beneath our feet. 

From plumbing to natural gas to electricty to internet connectivity and more, there's a whole world down there. Pipelines are in in your neighborhood, around the state, and across the nation. And there's a way for you to learn where they're located.
