Utility Markout Information

Once South Jersey Gas has scheduled your natural gas installation, you will receive a notification to mark out all private utilities and lines such as sprinkler systems, water lines, sewer lines, underground wells, septic systems, invisible pet fences and electric or water lines running to out buildings.

South Jersey Gas requests customers mark out privately run utilities and lines with flags or water based spray paint. You can choose to mark out these private utilities and lines yourself, or hire a private contractor to do this for you. We have provided a list of contractors who specialize in marking out private utilities and lines at the bottom portion of this page. 

South Jersey Gas or our contractor will contact New Jersey’s 811 call system, which will notify all public utilities running to your property such as electric, phone, gas, sewer, water and cable companies. For more on markouts, watch our video below.
