| Learn the risks of sewer line cross bores |
| Natural gas pipelines serving homes and businesses in urban and suburban areas are typically installed via trenchless boring methods that cause less disruption than open digging. National Grid currently uses techniques to detect sewer lines during trenchless boring, but some sewer laterals on private property may have gone undetected when natural gas lines were installed in the past. As a result, a gas line may have been bored or pierced directly through a sewer lateral in what is known as a “cross bore.”

|
|
| A natural gas line that is bored through a sewer lateral will impede the flow of sewage and eventually lead to a blockage. If you attempt to remove the blockage with mechanical equipment, you risk not only damage to the pipeline but also injury to personnel and damage to property. Gas may leak and travel into nearby sewer lines and buildings, causing a fire and explosion risk.

Protect yourself, fellow workers and the public. If you suspect a gas pipe is obstructing a sewer line, call National Grid at 1-877-370-5047. If a gas pipe has caused the blockage, National Grid will remove the pipe and make repairs at no charge. |
