Call Before You Dig

Call 811 before you dig.
It’s a no cost call.

Pipelines may be located anywhere, under streets, sidewalks or even your own yard. That is why it is important to know where they are before digging for any reason.

Underground Service Alert

Call Underground Service Alert (USA) at 811 at least two workdays before you start. This can help avoid costly damage or injury. USA will coordinate with SDG&E and other utilities to mark the location of buried utility-owned gas pipelines and other utility-owned lines, free of charge.

After Lines Are Marked

  • Once all lines are marked, carefully use only hand tools to dig within 24 inches of marked gas lines.
  • NO DAMAGE IS TOO SMALL TO REPORT. Even a slight gouge, scrape or dent to a pipeline or coating may cause a dangerous break or leak in the future.
  • If you cause what seems to be ONLY minor damage to a pipeline, OR ANY COMPONENT ATTACHED TO THE PIPELINE, you should STILL notify us immediately.
