Utility Markout Information

South Jersey Gas or our contractor will mark out all public utility infrastructure prior to digging on your property. Customers are required to mark out all private utilities and lines with flags or water-based spray paint. This includes sprinkler systems, water lines, sewer lines, underground wells, septic systems, invisible pet fences and electric or water lines running to out buildings.

You can choose to mark out these private utilities and lines yourself, or hire a private contractor to do this for you. You can find a list of contractors at the bottom portion of this page.
