Natural Gas Cross Bores
Be Safe! Always assume that obstructions involve a cross bore.
A cross bore is defined as the intersection of an existing underground utility or underground structure by a second utility installed using trenchless technology. This results in an intersection of the utilities, compromising the integrity of either or both utility or underground structure.
In rare cases, our gas pipeline may cross through a sewer pipe. If a plumber unknowingly strikes a gas line while cutting through a sewer blockage, natural gas could enter the sewer system, creating a dangerous situation. For this reason, it is extremely important to call 811 before you begin any digging project to have all utility lines clearly marked.
Where do cross bores occur?
When natural gas lines are installed in an urban area, trenchless technology (directional boring) is often used to dig horizontally underground. This helps alleviate damage to driveways, sidewalks, and landscaping.
When is it a problem?
At the time of the boring, a utility company may not be aware it has bored another utility company’s line. It becomes a problem when the sewer line develops blockage problems and needs to be cleaned.
What happens during the sewer line repair?
While cutting thru a sewer line block, a plumber can unknowingly strike the gas line. As a result, leaking natural gas can enter the sewer system.
Why is this important?
When natural gas enters a sewer system, it can create a safety risk.
