Before You Dig

WHO SHOULD CALL?

Excavators can be held liable for damages they cause to underground utilities. This is especially so if the utilities’ location was not marked by the utility company. Therefore, it is strongly recommended that the excavator for your project request all utility locations marked.  Every person planning to dig (using hand tools, power operated or power driven equipment) should notify USA North.

OUTLINE YOUR DIGGING SITE

Prior to your call to USA North, outline your digging location on paved surfaces with white: spray chalk, water base, UV paint or equivalent less permanent type marking; use flags, stakes whiskers, etc. on unpaved surfaces, Homeowners can use flour to enable USA North underground facility members to determine the area of digging to be field marked.

WHEN TO CALL

Two (2) working days to 14 calendar days before your planned digging. For your convenience make your call on Wednesday, Thursday or Friday afternoons to avoid communication delays.

HOW IT WORKS

USA notifies all member utility companies at least two days before an excavation is to be done. Each utility company marks the location of their facilities on the surface of the surrounding terrain. Each type of utility has a color code as follows:

  • Red – Electric
  • Yellow – Gas, oil, or steam
  • Orange – Communications or CATV
  • Blue – Water
  • Green – Sewer
  • White – Excavator’s digging site, marked by excavator before USA notification
