Some underground lines on private property are privately-owned and may not be marked by a utility. Other underground lines, between a meter and the home or business, may be considered privately-owned. In these cases a charge by the utility may apply to locate and mark those lines.
South Dakota 811 provides for communication between excavators and underground facility operators so buried utilities can be marked in advance of any digging. Following the South Dakota 811 procedure works to reduce damages to underground infrastructure, helps to ensure public and worker safety, and protects the integrity of utility services.
