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.
South Dakota 811 sends the location information to the utility companies that have underground lines in the vicinity of your worksite.
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.
Confirm all utility companies listed on your ticket have responded to the request after the two-business days have passed.
