About cross bores

The natural gas industry has been using trenchless technology for years to install its underground infrastructures. While this approach saves time, is cost-effective and has little impact on the environment, some natural gas lines installed using this technique may have inadvertently intersected with a sewer service line.

Before clearing a blocked sewer line, call Info-Excavation

A natural gas line could be obstructing the sewer service line using mechanical tools or a high-pressure water jet, you could inadvertently cause a gas leak or even a fire or explosion.

Before you attempt to clear a blocked sewer line beyond a building's walls, you must immediately contact Info-Excavation at 1 800 663-9228, option 1.
