had to choose the largest thickness to comply with the standard." Had the contractor
done so, they would have ended up with a
Trolining thickness that came out close to
the original required German design thickness, which was what was really required
in the first place.
Needless to say, the defendant settled
the case in favor of the contractor - all
because the standards were not properly
read and understood. The case took three
years to resolve with a lot of stress being
put on all parties, said Dr. Knight.

"It is the responsibility of the user of an
AWWA standard to determine that the
products described in that standard are
suitable for use in the particular application being considered," said the standard's
documentation. "This standard does not
describe the additional materials and procedures that may be required for difficult
conditions, such as those encountered in
building some submarine lines, casing pipe,
river crossings, and lines that are in rocky
areas or in severe soil stress. Consult the
manufacturer for the additional materials

and procedures that may be required for
these conditions."
The moral of this story? "You can't
assume that just because a product meets
a certain minimum standard it is capable
of performing in all conditions," concluded
Reece. "A standard is not an end in itself.
Rather, it is the starting point for developing a specification that addresses your own
unique operating environment. Ignore this
fact, and just down the road you could end
up facing the very problems you were trying to avoid."

A Minimum Standard May Not
Be Adequate
Corrosion is the great enemy of waterworks; from valves above ground to pipes
buried deep beneath the street. And it is
expensive: A 2001 study said the cost of
corrosion in the sewer and water sectors
exceeds $36 billion annually in the U.S.
alone, while effective corrosion protection of these systems could cut these costs
by 15-35 percent.
These numbers come from the
white paper, "Only Adequate in Ideal
Situations: Intentions and Limitations
of AWWA C217 and The Benefits of
Additional Certification Requirements for
Corrosion Prevention Systems in Water
and Wastewater." It was written by Stuart
Reece, Regional Sales Manager with Denso
North America.
Reece's paper explains why cold-applied
petrolatum tape systems (used to protect
connections and fittings against corrosion)
that meet only the AWWA C217 standard
may not be adequate in all conditions.
"The problem is that AWWA C217 is
based on average environmental conditions - normal or "ideal" conditions (in
the US) - but not, according to AWWA,
for unqualified use under all conditions,"
said Reece. "For example, your region's
unique soil chemistry (including soil conditions and the presence of contaminants)
may require a product with higher qualities than the C217 minimum to provide
protection against corrosion long term.
Unless you have done the necessary localized soil evaluation to see if this is the case,
you can't be sure that a product meeting
only the AWWA C217 minimum will be by
itself enough."
Excerpts from the AWWA C217-16
standard make this point readily clear.
