Underground Pipeline Basics

  • Transmission lines are large diameter pipes that move large amounts of natural gas from the delivery point into New Jersey to SJG’s distribution system.
  • Natural gas is delivered or distributed through underground pipelines or “mains” which are usually located along or under local streets and highways.
  • Smaller service lines connect to the mains to further distribute natural gas service to homes and businesses. These pipelines are a reliable, efficient and safe way to deliver natural gas throughout the region.
  • Serious incidents related to the transmission of natural gas are extremely rare in the United States and SJG has never had an accident on its transmission system since the original system was built in the 1960s.
  • American Gas Association statistics indicate the leading cause of pipeline damage is the result of people excavating. Other causes include corrosion, material defects, worker error and acts of nature.
  • SJG uses line markers to indicate the general location of our transmission lines. The markers are yellow and stand about 4 feet high. They are labeled, “Warning Gas Pipeline – South Jersey Gas.” All pipeline markers include an emergency phone number that is staffed 24-hours a day.
  • The strip of land over a transmission pipeline is known as the pipeline right-of-way (ROW). Local utility companies maintain the ROW to ensure the safety of the pipeline. SJG patrols its transmission lines monthly to look for damages or activities by excavators and ensure it is free from vegetation.
  • If a ROW crosses your property, please be sure that any fencing enclosing the area has gates to allow utility employees to gain direct access. The ROW must also be free of structures or obstructions so SJG can operate, test, inspect, maintain and protect the transmission lines. If existing vegetation needs to be trimmed and/or removed, SJG will contact you 10 to 14 days prior to clearing the width of our ROW.
  • If you notice any type of dumping of debris on our near our line, please report all illegal dumping to the police.
  • SJG asks everyone to help identify potential problems before they occur. If you or anyone you know is planning excavation activities make sure to contact New Jersey One Call by dialing 811 three days prior to digging so a technician can come out and mark out the area. It’s FREE and it’s the LAW. Once the site is marked, please respect all marks and hand dig within two feet of the buried pipeline.
  • Failure to contact NJ One Call can result in damage to underground utilities, causing disruption of vital services, property damage, fatal injury and fines up to $25,000.

To report any suspicious activities on or around SJG’s pipeline facilities, immediately call the police and SJG at 1-888-766-9900.
