Underground Utility Locating at work

Underground Utility Locating

The Underground Detective locates private utilities using state-of-the-art equipment for all pre-excavation and site planning needs. The state one-call (811) only marks public utilities, those which are before the service meter. Any utility beyond the service meter is usually considered private, which will require a second call to The Underground Detective.

Some examples of private utilities not located by the State One-Call:


  • Gas line to a heated swimming pool
  • Electric to a detached garage/barn
  • Sanitary or storm sewers


  • Parking lot lighting
  • Fire & domestic water mains
  • Any building to building utility
