What Is a Cross Bore?

Atmos Energy and other utilities that use horizontal or trenchless boring to install buried lines have discovered some locations where the utility line was installed accidently through a sewer line outside a home or business. When this occurs, we call it a cross bore. 

If a natural gas line is cut or nicked while unclogging a sewer line, it can create a serious hazard. Damaging a natural gas line can cause a fire or explosion and lead to even more serious damage or injury to those working on the sewer line and people nearby.
