Marking your ground (before digging it)

Here is something worth knowing: they are working up an "811" number that is a one-stop-call to do before digging. Utilities should contact you and/or mark your ground as follows:
  • Yellow: Gas, oil, steam, petroleum, or gaseous materials
  • Orange: Communication, alarm, or signal lines, cables, or conduit
  • Blue: Potable water
  • Purple: Reclaimed water, irrigation and slurry lines
  • Green: Sewers and drain lines
  • White: Proposed excavation
  • Pink: Temporary survey markings
