Identifying Underground Utility Markers

Underground facility markers are used to designate the general route of pipelines and other underground facilities. Markers are also found where pipelines and utilities cross a street, railroad or waterway, as well as areas where they emerge from the ground.

Pipeline markers mark the approximate location of the pipelines in the right-of-way and display the product, the pipeline operator’s name and the 24 hour emergency phone number.

Be Aware. Underground facility markers DO NOT:

  • Indicate an exact location.
  • Designate a straight line between markers.
  • Specify facility depth.
  • Signal the number of pipelines or utilities in an area.
