Markout Information

Your South Jersey Gas service is coming soon! Please mark out your property.

In preparation for natural gas service, the property owner is responsible for marking the location of all privately-run underground lines on the property using flags or marker spray, including, but not limited to:

  • Sprinklers
  • Septic Systems
  • Buried Oil and Propane Tanks
  • Underground Wells
  • Water and Sewer Lines
  • Invisible Pet Fences
  • Electric or Water Lines for Outbuildings

Markouts are used to show the contractor that something is buried underground.  Without your property being marked out, we may not be able to install your natural gas service. South Jersey Gas will mark out public utilities including cable, electric and phone. You can also hire a private contractor to mark your property. Below is a list of contractors who can perform this service.

For more information about marking out your property, please watch this short video.

We look forward to having you as our customer and providing you with safe, reliable, affordable natural gas!
 

Markout Flag Color Coding:

Red = Electric, Yellow = Gas/Oil/Steam, Orange = Communication, Blue = Water, Green = Sewer, White = Proposed Excavation.
