Gopher State One Call
State law requires that anyone digging in Minnesota must call Gopher State One Call (GSOC) before digging if using power equipment. Even if hand digging, you are encouraged to call if unfamiliar with the location of underground utilities.
Gopher State One Call is the state-wide notification center for excavating in Minnesota. There is no charge for this service. The service provides crucial damage prevention.
Calls requesting the marking of underground utilities should be made at least 48 hours prior to the start of digging. The person who is doing the digging is responsible for calling GSOC.
After the call is made, Marshall Municipal Utilities (MMU) along with other utility providers will be notified by GSOC to locate and mark any underground utilities in the specified area. MMU utility operators will mark our underground electric utilities with RED markings and our water utilities with BLUE markings.
After the underground utilities have been marked and the 48 hour time frame has elapsed, the excavation work may begin.
