How Far down should a Gas Line be Buried when Installing it to a House?

Jun 3, 2026

When installing a gas line to a house or a detached structure in Colorado Springs, proper burial is essential for safety and code compliance.

According to local utility codes, residential gas lines must be buried at a specific depth:

  • Standard Burial Depth: Gas lines should typically be buried between 18 to 24 inches deep. This depth is required to protect the line from surface activities such as foot traffic and landscaping.

In addition to the specific depth, there are other critical safety standards for underground gas lines:

  • Tracer Wire: If the gas line is made of plastic (common for underground runs), it must be installed with a tracer wire. This allows the pipe to be located with a detector in the future to prevent accidental damage during excavation.
  • Backfilling: The trench must be backfilled with specific materials, such as sand, to provide a cushion for the pipe before the soil is replaced.
  • Professional Installation: Because these lines must pass a final inspection and adhere to strict safety regulations, it is highly recommended that you hire a licensed professional to ensure the installation meets all local requirements.
