 utility location.


The primary function of the above ground pipeline markers is to identify location and alert those who might be working in the area.  In accordance with the PHMSA, underground pipelines should be marked with permanent pipeline markers in a "line-of sight" fashion to indicate presence and location.  These pipeline markers should also carry the type of pipeline ex: Natural gas, and contact information of the company that operates the pipeline.

With the demands for more bandwith combined with increased competition and regulatory changes, there has been an explosion of long-distance, fiber optic cable deployment.  According to one study, nearly seven million miles of cable was installed in North America in the year 2000 alone.

The Natural Gas Industry will enjoy double-digit growth over the next decade with natural gas currently supplying one-third of our nation's total energy needs.  Natural gas utilities operate and maintain more than 1.2 million miles of underground pipelines.

Billions of dollars are spent in installing, maintaining, and upgrading buried utility service lines.  Isn't it ironic that all this technology can be immobilized by a $50 shovel?
