    One free, easy call can keep you safe from injury and expense. Before any digging or earth moving, whether by a homeowner or a professional excavator or contractor, state law requires calling 8-1-1 to notify the local One-Call center at least 48 hours or two full business days prior to the scheduled excavation in order to have underground utilities located and marked free of charge.

    Visit your state's 8-1-1 center to learn more:

    Color codes for digging safely

    The flags and paint markings used by our technicians when marking underground lines indicate the type of utility/facility that lies below. Here's a guide to help you interpret what each flag color means:

    • Red - Electric
    • Yellow - Gas, oil, or steam
    • Blue - water
    • Orange - Telephone - CATV
    • Green - Sewer
    • Purple - Reclaimed water
    • Pink - Temporary survey markings

    Working around marked areas

    Do not remove the flags, stakes or paint marks until you have finished digging. Once the property is marked, dig responsibly and respect the marks. Regardless of depth, always hand dig within 24 inches on either side of a marked line.
