Call before you clear

What you need to know before clearing a sewer line

When utility lines are installed underground, it is possible that some unintentional intersections or “cross bores” have been created. A natural gas line crossing through a sewer pipe is rare, but they can co-exist safely and go undetected until the sewer pipe is blocked and needs to be cleared. If a cross bore is present, clearing the sewer can damage the natural gas line and potentially cause a safety hazard for surrounding homes and businesses. 

By calling BC One Call before you begin clearing a blocked sewer, you can find out if natural gas lines are intersecting the sewer line and prevent accidents and damages from happening.
