Our nation’s dependency on water amplifies the need for responsible care and proactive steps towards preservation. Water, potable, gray water and containment systems are made up of physical assets… assets that are constantly aging and deteriorating. The reality is, it’s only a matter of time until more severe (and costly) action will be necessary. Fortunately, something can be done to arrest this process via corrosion mitigation.
3. How Stark is the Reality?
03
Stringent air quality
legislation and new
“effluent guidelines”
may result in
increased
concentration of
corrosive species in
water treatment
systems.1
Corrosion
responsible for 50%
of forced outages in
steam generating
plants.2
U.S. power grid
outages have risen
by 285% since 1984.3
Increasing demands
on our national
power grid, both due
to population growth
and tech demands,
growing at a rapid
pace: U.S. Population
Growth =
approximate 2.5
million per year.4
Electricity demand
rose approximately
10% between 2006
and 2016.5
4. How Great is the Cost?

7. What is Corrosion?
07
The physical properties of metal are
constantly in flux. This “disintegration
of metal” occurs through an
electrochemical process that starts on
the metal’s surface, as part of its natural
behavior.
As such, corrosion of steel rebar used
to reinforce concrete, causes cracking
as the byproduct of corrosion.
8. Causes of Corrosion
Water / moisture (humidity)
Acids
Bases
Salts
Oils
Within these power distribution
facilities and systems, the metallic
form will continually corrode due
to a variety of factors:
8
9. 9
Assessment Selection and Engineering
While non-metallics and other
composite materials may mitigate
corrosion problems, costs can be
prohibitive and many are untested
for structural applications.
If metals are selected they must be
protected.
10. Corrosion Prevention
Some of the common coatings used are: Ultra-High Solids
(Plural Component) Coatings, Poly Urea, High Performance
Acrylics, High Performance Alkyds, Alkyd Esters and
Acrylics, Epoxy Esters, Pre-Catalyzed Epoxies, Moisture
Cured Urethanes, VOC Compliant Coatings, Powder
Coatings, Metalizing, Vinyls, Radiation Cured Coatings,
Sacrificial Coatings, and Vulcanized Rubbers.
Technological advancements in the formulation of coatings,
the expertise necessary to choose the appropriate coating
solution for each infrastructure asset, the proper
inspection by certified coatings inspectors and the proper
surface preparation and application by certified coatings
applicators, has increased the professionalism of the
industry and elongated expected performance life-cycles,
all of which fosters asset protection.

12. It is a paradoxical problem… the resources needed to provide service
to the grid siphon away efforts to prolong the life of the system, which
protects against costly outages.
However, if we only focus on the short-term economics, we may lose
sight of the ”long-view” savings.

15. Stringent Industry Standard
enacted in 2004.
Standard shows proficiency in:
Environmental Safety and Health;
Process Control; Materials; Surface
Preparation; and Coating Application.
Certification Test: Is administered by a
3rd Party and tests knowledge, skill and
overall proficiency.
What is the “NACE 13/SSPC ACS-1 Standard?”

16. Inspector and Specification Writer Programs
The Protective Coatings Specialist Program (PCS) –
introduction to coatings and linings used to control
corrosion… defines and examines common coatings,
addressing when, how and why they should be used.
NACE Coating Inspector Program (CIP) – for over 30 years,
the “gold standard” for inspections in the protective
coatings industry.
16
The SSPC Protective Coatings Inspector Program (PCI) –
training in proper methods of inspection for surface
preparation and installation of industrial and marine
protective coatings and lining systems.

US Navy’s Naval Facilities
department (NAVFAC) did a cost-
benefit analysis regarding the use
of certified or non-certified
contractors on coatings projects.
The results showed that utilizing
certified contractors and trained
personnel has proven an
overwhelming “cost-benefit” success
in particular as it pertains to time.
