Cross Bore Information

A cross bore occurs when a utility line is drilled, or bored, into or through another utility’s line (see image below).

Be Aware of Sewer Backups & Repairs

In the event that a gas line was accidentally installed through a sewer line, the cross bore can create a sewer backup in the home.

Sewer backups can result from a variety of issues. Check for a potential cross bore when determining what is causing a sewer backup. (Customer does not have to have natural gas service to experience a sewer issue due to a cross bore).

Before anyone uses a tool to clear the clogged sewer line, we suggest using a camera to check for a cross bore. If you do not have a camera, call us at 800‑959‑5325.

Using any type of line clearing tools could damage the gas line, allowing gas to escape. Gas that escapes can migrate, or travel, and enter buildings and homes. Under certain circumstances, the gas could ignite and lead to injury or death.

If you discover a cross bore, call us at 800‑959‑5325.
