Call 811 Before You Dig

Pipelines may be located anywhere, including under streets, sidewalks and private property, sometimes just inches below the surface. Excavation, planting, demolition and other forms of digging are a major cause of pipeline damage. That’s why it is important to know where they are before you begin any type of digging.

Whether you’re planning to build a major development or just landscaping your yard, protect your safety and the safety of those around you by calling Underground Service Alert at 811, at least two business days prior to excavating. You may call Underground Service Alert between 6:00 a.m. and 7:00 p.m., Monday through Friday (excluding holidays). Underground Service Alert will coordinate with Southern California Gas Company (SoCalGas) and other utility owners in the area to mark the locations of buried utility-owned lines. This is a FREE service and it can help prevent injury, costly property damage and loss of utility service.

What to Do

  • MARK OUT your proposed excavation area in white paint or provide other suitable markings.
  • CALL Underground Service Alert at 811 from 6a.m. to 7p.m. Monday through Friday (excluding holidays) at least two business days before digging.
  • WAIT until SoCalGas either marks its gas pipelines and indicates pipe material and diameter – or advises you the area is clear of its pipes before you start digging.
  • REMEMBER that SoCalGas uses only yellow paint, flags or stakes to mark out the location of its gas pipes. Other utility owners use other colors to mark their telephone, communications, water or other underground lines.
  • USE ONLY HAND TOOLS within 24 inches of each marked utility line to carefully expose the exact locations of all lines before using any power excavation equipment in the area.
  • REPORT any pipe damage by calling us immediately at 1-800-427-2200. No damage is too small to report. Even a slight gouge, scrape or dent to a pipeline, its coating, or any component attached to or running along side the pipe, such as a wire, may cause a dangerous break or leak in the future. Learn more about what to do if you damage or suspect damage to a pipeline or meter.
