Locate Underground Utilities
Over the years, more and more of
our utilities are being buried in the ground. Some
are placed there due to necessity, such as water, sewer
and gas lines or underground storage tanks. Others are often placed underground
for aesthetic reasons. This usually includes telephone,
television and Internet cable, and electrical power
This buried infrastructure is
important to the day-to-day functioning of our homes and
our businesses. It is
critical that it not be disturbed or in any way damaged.
Yet, there is a constant need by municipalities and the
public to dig into the ground. Governments and
contractors need to disturb the ground to install more
underground utilities, widen a road or construct a new

It doesn't matter if you are a public works department,
a contractor or a do-it-yourself homeowner, it is
critical that you know where all underground utilities
are located. Failure to locate underground
utilities before you dig can result in disruption of
services to individual homes or entire neighborhoods.
Even worse, cutting into some buried cables or pipes can
result in injury or death.
pipes and cables can be hard to find. In some
instances, they have been recorded on GIS mapping.
In many cases, however, there is no record of where this
underground infrastructure has been buried. In
either case, though, a qualified underground utility
locating service is needed to find and visibly mark the
location of every buried utility. Some may think
that all you need to find these buried items is a metal
detector. But that is far from accurate.
Drainage lines and irrigation systems often contain no
metal. Electric lines can be deeper than a
standard metal detector can sense.
To find all types of items that
can be buried, most underground utility locating
services today use Ground Penetrating Radar (GPR)
In many communities, "call before
you dig" phone numbers are listing at the beginning of
local telephone directories. This is especially
useful for homeowners who are planning some excavation
work in their yard.
