Have you ever pulled into your street or driveway and wondered what the colored lines on the pavement or in your yard meant? These color-coded marked lines identify the approximate location of underground utility lines and more. The Uniform Color Code for marking underground utility lines from American Public Works Association (APWA) is as follows:

  • RED  Electrical Power Lines, Cables, Conduit and Lighting Cables
  • YELLOW  Gas, Oil, Steam, Petroleum or Gaseous Materials
  • ORANGE  Communication, Alarm or Signal Lines, Cables or Conduit
  • BLUE Potable Water
  • GREEN  Sewer and Drain Lines, Utility Line
  • WHITE  Proposed Excavation
  • PINK  Temporary Survey Markings
  • PURPLE Reclaimed Water, Irrigation and Slurry Lines

Always Call 811 BEFORE You Dig Anything!

One call gets your utility lines marked and helps protect you from injury and expense. It’s easy and it’s the law! One of the worst mistakes is not identifying exactly where lines are buried on the property. And, there may be more buried than you realize. Avoid the costly and potentially dangerous mistakes associated with accidentally unearthing your underground power, gas, cable, phone and water lines. You may also have irrigation water lines or even long buried electrical fencing conduits. 811 can help you locate these lines and avoid cutting through them or accidentally unearthing them.

PES reminds everyone that if you have plans to build, dig, excavate or install any of the following you must call 811 a few days before the work is performed!
