They are two words no contractor or municipal engineer wants to hear: cross bore. A cross bore is what happens when one underground utility intersects another. Most worrying is when a gas line punches through a sewer main or lateral. Cross bore risk has risen with the use of trenchless technologies like horizontal directional drilling, because the operator can’t physically see what’s in the immediate vicinity of the drill bit.

"Even ONE is a concern"
Left untouched, a cross bore isn’t a danger on its own. But over a period of years, sediment can build up around the intruder and block the sewer line. When a contractor tries to clear it, trouble can ensue.
And that trouble can be of the worst kind. In June 2012, a plumber punctured a gas line while attempting to clear a blocked sewer lateral at a home in Indianapolis triggering an explosion that levelled the house. Fortunately, everyone inside made it out in time and there were no injuries. I would say there neighbors were NOT HAPPY!

Can Cross Boring be Prevented?
Bonnie, Great question
YES 100% it can be prevented. Cloud 9 has been preventing cross boring pipes in Central FL, for 20+ years. A quick video pipe inspection will give the boring company the location, depth and the size of the crossing pipes.
