ADS PIPE CHOSEN FOR NEW DE-ICING PADS IN ATLANTA
It’s the perfect solution to the problem of
what to do with storm water and de-icing
runoff at Hartsfield Atlanta International
Airport: ADS N-12 ProLink WT® high
density polyethylene (HDPE) pipe. The pipe
is buried underground and will be used as a
containment system for all runoff from the
airport’s first de-icing facility. It was chosen
for its ability to handle chemicals and the
weight of a jumbo jet at a 25-foot burial
depth. The inert properties of HDPE pipe
allow it to handle strong solutions ranging
in pH from 1.5 to 14. The de-icing solution
primarily consists of ethylene glycol that will

the sections does not require a separate
coupler for a watertight connection. The integrated design also makes it easy for the crew
to slip together the pipe sections.”
The pipe’s strength allows it to be buried
25 feet below the de-icing pad, covered with
No. 57 stone, then 3,000-4,000 pounds of dirt.
At that burial depth, with proper
compaction, it effectively handles the weight
of the aircraft above it.
Proven to be the right pipe for the job, it’s also
the right price. SDL Environmental President
Thomas Boynton estimates that by using ADS
pipe instead of ductile iron or reinforced concrete, the cost of the facility was cut by a third
to a half. He also estimates that his crew saved
at least a week of work. It took three weeks to
complete the de-icing pad with HDPE pipe and
it would have taken four to five weeks to install
ductile iron or concrete, according to
Boynton. “ADS N-12 pipe is lighter than
ductile iron or concrete and easy to assemble.
With it, we can build the retention system and
begin covering it with backfill in one day,” said
Boynton.

N-12® PIPE IN WISCONSIN IS STRONG AND STEADY
AFTER 11 YEARS UNDERGROUND
The Wisconsin Department
of Transportation conducted
a video inspection and found
the pipe and its joints to be in
great shape, with no defects.
After spending 11 years under heavy traffic, ADS N-12®
HDPE pipe in Door County, Wisconsin has greatly exceeded
expectations. The installation was a test run when the product was first on the market. N-12 pipe had never before
been used in this type of application, but the Wisconsin
Department of Transportation had enough confidence in the
product to try it. With 40% more traffic than expected using
the road on a daily basis, the pipe is performing ideally.
More than 1,600 feet of N-12 pipe was installed in 1988 as
a storm sewer in Fish Creek under State Highway 42. It
performed so well, the DOT forgot it was there. It has since
found out N-12 pipe was a sound decision. Last year, the
Wisconsin Department of Transportation conducted a video
inspection and found the pipe and its joints to be in great
shape, with no defects. That is a true testament to the
strength and durability of the pipe, buried a foot below the
surface of the road with an average of 6,300 vehicles using
that route last year alone. The current state maximum for
HDPE pipe at that burial depth is 4,500 vehicles per day.
“We knew we would only be able to bury the pipe a foot
under the road and the N-12 pipe was the strongest choice
3
for that application,” says Mike Leitzke, Wisconsin DOT
project manager. “For other materials, we would need at
least a foot and a half. We chose to use N-12 pipe mainly
because of its strength, but also because it’s flexible and
lightweight. The pipe had to come down the bluff and go
under the road and we knew concrete would crack. The
N-12 pipe was flexible enough to hug the land and bend
where we needed it to bend. Plus, the project was in a sensitive area and we didn’t want to have to use cranes or backhoes that are needed for concrete pipe. Two or three guys
could easily move the lengths of N-12 pipe around without
disturbing the bluff.”
Because the pipe is strong and installed properly, at its minimum burial depth it can handle the load of the extra traffic
above it and additional force from the rolling motion of the
vehicle. The durability of N-12 pipe is also apparent in this
case. Abrasive materials are passing through the pipe without any damage to it. This helps prove the point made in test
after test that it takes longer for abrasive material to erode
HDPE pipe than concrete pipe.
“The key characteristic of Door County is that the people
there are very concerned about the land and are vocal about
it, “ says Leitzke. “It’s hard to remember to go back and
check every project, but if it had been breaking down even
the slightest bit, we would’ve heard about it. That’s why it
was no surprise to hear the inspection found the pipe to be
in perfect condition.”
N-12 pipe was introduced on the market only a year before
it was put in the ground under Wisconsin State Highway 42.
The Wisconsin DOT was willing to try a better alternative to
traditional materials. Its confidence in N-12 pipe paid off.
The pipe is proving it can stand the test of time.
PROTECTING
THE ENVIRONMENT
N-12® PIPE KEEPS FARMS IN LINE WITH EPA REGULATIONS
Several years ago, no one thought much
about animal waste. But with the size of
animal feed operations (AFOs) growing into
thousands of animals, concerns about
pollution in the groundwater and the nation’s
streams have come from the agricultural
c o m m u n i t y, t h e pu bl ic , a n d t he
Environmental Protection Agency (EPA).
Under the Clean Water Act, the agricultural
community is doing all it can to protect the
environment and public health by developing
Comprehensive Nutrient Management Plans.
One way the agricultural community is
addressing the situation is with waste lagoons
and directing clean water away from the
sites. In an effort to protect the environment
from the hazards of animal waste, AFOs
around the country are beginning to use ADS
corrugated high density polyethylene (HDPE)
pipe for this type of waste management. The
long-lasting, watertight pipe transfers
manure underground from barns to lagoons,
keeping groundwater clean. It’s a better
system for handling animal waste than a
manure pile because the pipe’s inherent
physical properties of chemical inertness and
watertightness protect public health and
keep odor to a minimum.
Because of the stiffer regulations called for by
the Clean Water Act and the potential threat
of animal waste to surface and ground water
quality, civil engineers are becoming more
involved with the design of animal waste
lagoons. The systems they develop have soils
and embankments that are highly compacted
so as to limit the seepage of any animal waste
into the water table. Because they go to such
great lengths to make sure there is no seepage
out of the lagoon, it only makes sense that the
pipe they choose to transfer the waste to the
lagoon would be leak-free.
In a town near Green Bay, Wisconsin, farmer
Carl Theunis has 1,800 cows. He buried
2,400 feet of 18-inch, 24-inch, and 30-inch
diameter ADS N-12 ProLink WT® HDPE pipe
to construct a manure gravity flow system and
a storm sewer system. His animal feed operation utilizes two 8,000,000-gallon capacity
lagoons. The storm sewer system diverts
clean rainwater away from the site. Besides
being easier to handle, Theunis has found that
the lagoons allow a natural “cap” to form on
the waste which significantly reduces odor.

“Using watertight pipe to transfer the manure
addresses the pollution aspect very well,” says
Theunis. “And since ADS pipe doesn’t corrode, we
won’t have to come back in a few years and dig it up.”
ADS Agricultural Market Manager Kevin Rapp
explains N-12 pipe was chosen for the project for
a number of reasons. “HDPE pipe is chemically
inert, making it an ideal choice for manure
handling systems. The acidic nature of manure
slurries will not affect our N-12 pipe.”
Traditional drainage pipe materials like concrete
and steel have varying levels of resistance to chemicals. Acidic chemicals and saline conditions can
deteriorate concrete, steel, and aluminum.
Animal waste lagoons are just as helpful to those
running small farms. USDA data shows that out of
nearly a half-million agricultural operations
nationwide, about 85% of them have fewer than
250 animals. Tim Doyle has a 100-acre, 160-head
dairy farm in Vermont. Five years ago, Doyle built
a lagoon 100 feet from his barn and used 30-inch
ADS N-12 pipe to move the manure into it.
Up to 48 inches in diameter, ADS N-12 ProLink WT
pipe is watertight. That means the joints have
undergone the ASTM (American Society for
Testing and Materials) D 3212 lab test which
misaligns and deflects the joint while maintaining
an internal water pressure of 10.8 psi for ten
minutes. Integrity comes from not only the
strength of the joints, but also from the fewer
amount of joints needed in an HDPE pipe system.
The pipe comes in lengths of 20 feet, requiring
fewer joints than other types of pipe.
“Without this pipe’s size and smooth inner walls,
we would be constantly reaming out the pipe to
move the bulky material,” Doyle says. “And since
the National Resources Conservation Service
(NRCS) helped fund the project, it was very
particular and had an inspector on-site to make
sure the system would not leak. The ADS pipe
provided the required watertight seal.”
