The 811 Process
Get To Know How It Works
Step 1 – Notify 811
Notify South Dakota 811 at least two-business days prior to excavating by dialing 8-1-1 or by processing a request to dig online here.
- Provide the type of work being done, and address or driving directions to the worksite along with other information to help the locators identify where the work is taking place and how to accurately respond to your request.
- You’ll receive a confirmation number with your locate request. You should keep this number for the life of the ticket, 21 days.

Step 2 - 811 Will Notify Utility Companies
South Dakota 811 sends the location information to the utility companies that have underground lines in the vicinity of your worksite.
- Utility companies provide South Dakota 811 with the location of their underground utilities. South Dakota 811 uses this information to identify and notify the utility companies who have lines within you worksite.

Step 3 – Locate Utility Lines
Each utility owner locates their underground lines themselves, or uses hired contractors to locate their underground lines within the two-business days. If a utility owner does not have utilities in your worksite, they will provide an “all clear” to let you know their lines are not within your worksite.

Step 4 – Confirm the Marks
Confirm all utility companies listed on your ticket have responded to the request after the two-business days have passed.
- A second request can be made if a utility company does not respond within the allotted time. This request goes out as a “priority” notice to the utility companies that have not responded.
