SD One Call

Use South Dakota One Call to locate underground utilities before you dig. Excavators planning to dig, drill or trench should make the required locate request to South Dakota One Call two working days before the planned work. Homeowners and landowners planning their own excavation activities are required to notify South Dakota One Call as well.

Make your locate requests by simply calling 811 and (800) 781-7474 outside of S.D. Locate requests are accepted 24/7. The One Call service is free to excavators.

The South Dakota One Call system provides for communication between excavators and underground facility operators so buried utilities can be marked in advance of any digging. Following the One Call procedure works to reduce damages to underground infrastructure, helps to ensure public and worker safety, and protects the integrity of utility services.
