Preface
Introduction
The ES-38TM for Sewer Laterals represents
the next generation in sewer leak detection.
Measuring the variation of electric current
flowing through the walls of a sewer pipe, the
ES-38TM represents the state-of-the-art in
locating defects that cause infiltration and
exfiltration.
Electro scanning, in contrast to visual
inspection techniques commonly used by
closed-circuit television equipment, locates
all potential cracks and fractures that
represent pathways where water can either
leak into or out of a sewer pipe. If a pipe
leaks electricity, it will leak water.
Most sewer pipe materials such as clay,
plastic, concrete, reinforced concrete, and
brick have high resistance to electrical
current, while defects have low resistance.
As a result, the ES-38TM is your new tool of
choice to help you cost-effectively find pipe
defects and confidently recommend fixes to
your Customer.
Operating Conditions & Safety
The use of the ES-38TM requires access to
sanitary sewer laterals, involves filling
sewers with water, and sometimes operating
along the side of roads, easements, and other
hazardous locations that represent safety
hazards. This User Guide DOES NOT
describe the hazards likely to be encountered,
nor required safety procedures and
requirements that must be carried out when
operating in these hazardous environments or
conditions.
Therefore, operation of the ES-38TM is at the
sole responsibility and risk of the Operator,
who bears full responsibility to ensure that
the required safety procedures for work is
known and carried out.
