Why do you need to call before clearing a sewer blockage?

"Trenchless" technology or "directional boring" is often used to install natural gas lines underground.

This is the preferred method of installing new gas lines nationwide because it minimizes disruption to landscaping, sidewalks and streets. Precautions are taken to avoid sewer lines, but in some instances a natural gas line can intersect with a sewer line. This situation is called a "cross-bore."

In instances where a cross-bore exists, sewer rodding equipment such as augers and root cutters can penetrate the gas line and lead to the dangerous release of natural gas.
