Call 811 before you dig!

Call 811 before you dig!

Whether you are planning to do it yourself or hire a professional, smart digging means calling 811 before each job.

State and federal laws require anyone excavating to contact every potentially affected operator of underground facilities before starting to dig. North Carolina requires two business days notice and South Carolina require three business days notice, excluding weekends and holidays.*

One easy phone call to 811 quickly begins the process of getting underground lines marked. Local One-Call Center personnel will notify affected utility companies who then send a crew to mark underground lines for free.

Simple digging jobs can damage utility lines and disrupt vital services to an entire neighborhood, harm those who dig and result in expensive fines and repair costs. Marked lines show those who dig the approximate location of underground lines and help prevent undesired consequences. Knowing where underground utility lines are buried before each digging project begins helps to prevent injury, expense and penalties. The depth of utility lines may vary and multiple utility lines may exist in one area.

Not all underground facility owners are One-Call members.

Helpful Hints:

  • Always dig around the marks — not on them! Some utility lines may be buried at a shallow depth and an unintended shovel thrust can bring you right back to square one — facing potentially dangerous and/or costly consequences.
  • Excavation equipment can cause major damage to underground utilities. A best, safe practice is to “hand dig” within 30 inches of the locate markings on the ground.
  • Erosion or root structure growth may shift the locations of your utility lines, so remember to call again each time you are planning a digging job. Safe digging is no accident. Know what’s below. Always call before you dig.
  • If excavating, ditching, trenching, drilling, or blasting is to be done on or adjacent to your property, check or call your state One-Call system.
