2. Over time, drain pipes develop problems that lead to slow drains, backups, leaks and possible breaks and damaging
spills. Common drain clearing remedies for underground pipes may not be feasible in buildings and will not extend
the useful life of the pipe while replacement is an expensive and disruptive option. Fortunately, Nu Flow has a
patented process to rehabilitate pipes in place and restore drain performance.
For example, Nu Flow rehabilitated the pipes for a customer
experiencing recurring backup problems throughout their building.
This is a long-term and cost-effective solution that was also not
disruptive to the building’s many tenants.
Project: Clean and line corroded drain system without displacing
residents using Nu Flow’s trenchless structural drain liner.
Customer: Riverside Park Apartments, a private non-profit
organization in Jacksonville, Florida.
Site: Riverside Park Apartment Building, a nine-story high rise built in
1981 with 90 units.
System: More than 1,200 feet of 3” and 4” cast iron vertical drain
stacks and 400 feet of 3” to 8” underground pipe including multiple
bends and size changes. The sanitary system extends nine stories
and transitions under the ground and then to the outside of the
building.
Situation: The pipes at Riverside Park Apartments had been
neglected for many years to the point that the 4” kitchen stacks had
corrosion and grease buildup that reduced the opening to less than
the diameter of a dime. The corrosion and clogged drains caused
many backups throughout the building; so many that plumbers were
coming in every week to deal with the recurring issue.
Solution: While rehabilitating the system, Nu Flow was able to bring
the pipes back to original diameter, which was a challenge as the
pipes were so badly corroded. With limited access from the roof and
service closets on the ground floor, Nu Flow retrofitted the pipes with
their patented Nu Flow process by pulling a seamless structural liner
into place. The pipes were rehabilitated without the need to displace
residents and since completion Riverside Park Apartments has not
experienced any of the previously recurring issues.
Corrosion and backups are common in commercial, industrial and
residential buildings. Whether you are experiencing problems now
or are interested in preventing the inevitable failure of your plumbing
system, Nu Flow is available to restore your peace of mind.
The patented Nu Flow process
returns
pipes back to original diameter
while avoiding destruction and
occupant displacement.

4. Location: Carlton, Wisconsin
Situation:
Part of a 6” diameter drain pipe encased in concrete was
leaking 10 feet under a concrete structure. Breaking through
the concrete to access the pipe was not an option.
Solution:
Nu Flow rehabilitated the leaking pipe with our Pull-in-Place
structural liner and created a seamless pipe inside the host
pipe without disrupting the plant’s normal operations. Nu
Flow contracted a scuba diver to work at the discharge point
below the waterline in Lake Michigan.

Kewaunee Nuclear Power Plant: Underground Drain Rehabilitation

5. Location: Houston, Texas
Situation:
This 41-story, commercial building in downtown Houston
had a cracked storm drain main line that leaked. This cast
iron main is located in an underground pump room, hoisted
about 30 feet above the floor. The pipe line is exposed, but
surrounded by electrical lines, cooling fans and air ducts.
Solution:
The main line access points were hard to access and a
traditional repipe would not have been feasible. Nu Flow
technicians rented a lift to access the pipe, cleaned it and
installed Nu Main, a protective epoxy liner. There was not
any destruction to the building or disruption to the tenants.

Marathon Oil Tower: Storm Drain Main Line Rehabilitation

6. It is well known that non-invasive angioplasty or arthroscopic procedures are preferred to open-cut surgery. The
same is true when it comes to rehabilitating the plumbing infrastructure within your facilities. Over time, all drain
systems develop problems, begin to fail and require attention. Replacing those pipes comes with the need to dig
through floors and foundations or to cut through walls to access the pipes, which can be very time-consuming,
costly and disruptive.
However, this can be avoided by using Nu Flow’s non-
invasive equivalent to angioplasty to clear pipes and
install their version of a stent in order to rehabilitate
failing lines and to strengthen weakened areas.
Project: Remove corrosion and build-up and line
under-foundation drain pipe using Nu Flow’s trenchless
cured-in-place structural drain lining technology.
Customer and Site: Long Beach Memorial Medical
Center, one of the nation’s top-rated medical centers
located in Long Beach, CA.
The 54-acre campus and hospital houses 716 beds,
employs more than 5,200 people and has more than
400 volunteers.
System: 100 feet of 4” cast iron pipe running 4 feet
under the Pharmacy and Sterile Process Department
to the 6” mainline beneath a hospital hallway.
Situation: The system was experiencing failure and backups due to erosion and corrosion over the past 60 years.
In some places the erosion was so severe that the bottom of the pipe was missing. Before the hospital learned
about Nu Flow, they were preparing to replace the pipe, which would require moving the SPD Department, setting
up temporary walls, saw cutting the concrete, hauling out the debris by hand, completing the repipe and then
rebuilding everything to finished surfaces.
Solution: Nu Flow saved the customer from the cost and logistics of replacing the system, which would have
caused extensive damage to the hospital. Using trenchless technology and existing access points to the drain
system, Nu Flow removed all buildup and corrosion, returning the pipes back to their original inside diameter. Nu
Flow then retrofitted the pipes with the patented Nu Flow process by pulling 100 feet of seamless structural liner
into place, greatly extending the pipes useful life. The Nu Flow solution can install a new liner even where the old
pipe is missing.
The resulting solution restores the flow capacity of the drain pipes and returns the system and facility to service
quickly. The hospital avoided the need to repipe the area, saving valuable money and six weeks of construction.
Aged and failing pipe systems are common in commercial, industrial and residential buildings. Whether you are
experiencing problems now or are interested in preventing the inevitable failure of your plumbing system, Nu Flow
is available to restore your peace of mind.
“In 20+ years, I have not been this
impressed with a new technology.”

7. Location: Kahala District of Honolulu, Hawaii
Situation:
PVC storm drain pipe had root intrusion, causing leaks and
backups. Portions of the pipe were below the water level at
high tide, causing sea water exfiltration from the pipe into an
area that is used to host weddings.
Solution:
Nu Flow cleaned the storm drain pipe and installed our
patented Pull-in-Place structural liner to prevent future
problems in the pipe system. Nu Flow completed the retrofit
without digging a trench, preserving the picture-perfect
landscape and hardscape.

Kahala Hotel & Resort: Storm Drain Rehabilitation

8. Location: San Diego, California
Situation:
The drain system for this contemporary dive bar experienced
backups and leaked sewage into the ground. The 4" wide
cast iron pipes were found to be heavily corroded, cracked
and had pieces of pipe missing. The customer wanted the
pipes rehabilitated during the bar’s scheduled renovation.
Solution:
Nu Flow was selected to rehabilitate these underground sewer
pipes because our trenchless technology permits us to clean
and line the pipes without causing destruction or disruption
to the remodeled building and contractors. We saved the
customer from the cost, time and damage of a re-pipe.

9. Location: Coronado Island, California
Situation:
The 35-year-old kitchen drain pipes in the 15-story beach
front condominium were clogging, cracking and leaking. The
kitchen stacks are located inside walls and ceilings and consist
of 4” cast iron pipes.
Solution:
Nu Flow cleaned and descaled the pipes back to their original
diameter. We lined all of the kitchen risers in the 135-unit
condominium with our patented Pull-in-Place structural liner
without having to tear out walls, floors or ceilings that would
have been necessary in a traditional re-pipe project.

La Princesa Tower Condominiums: Drain Stack Rehabilitation

10. Over time, all drain systems develop problems, begin to fail and require attention. Replacing those pipes comes
with the need to dig through floors and foundations or to cut through walls to access the pipes, which can be very
time-consuming, costly and disruptive. However, this can be avoided with a pipe retrofit from Nu Flow.
Project: Rehabilitate a failing drain pipe without disruption
to the airport’s operations.
Customer and Site: Lester B. Pearson International
Airport, located in Mississauga, Ontario, is the largest
and busiest airport in Canada.
System: 3” cast iron drain line running from the bottom
of an elevator shaft to a collecting pit. The pipe is located
five feet under concrete and is used to drain the elevator
shaft from hydraulic oil and other fluids that accumulate
during operation and maintenance.
Situation: When it rained, water in the ground infiltrated
the pipe and consequently filled the collecting pit with
water. High underground water levels exerted high
pressure on the pipe and even a small leak was filling
the pit.
Solution: A CCTV investigation was carried out and
revealed that two joints in the pipe were allowing the
infiltration.
Nu Flow retrofitted the failing pipe by inserting a Pull-in-Place structural liner in the existing pipe using the patented
Nu Flow process. The liner cured overnight and the pipe returned to service the next day. With the Nu Flow liner in
place, the drain pipe is completely sealed with a seamless solution that will prevent further infiltration.
Problems with drain lines are common and recurring. Whether you
are experiencing problems now or are interested in preventing the
inevitable failure of your plumbing system, Nu Flow is available to
restore your peace of mind.
The patented Nu Flow process avoids
the need to dig or rip out walls to retrofit
your pipes. With multiple piping solutions
we can rehabilitate any pipe, anywhere.

11. Nu Flow prides itself on having an extremely efficient,
budget-friendly solution for healthcare and medical
buildings. Moving around patients and closing surgical
rooms can be a decision that puts lives at risk, so Nu Flow
is happy to provide nondestructive solutions that keep
normal operations undisturbed, while greatly extending
the lifespan of necessary pipe systems within the building.
Project: Use the patented Nu Drain system to rehabilitate
a failing rain leader without having to displace patients.
Customer: Huron Perth Healthcare Alliance manages
four hospitals in Ontario, Canada.
Site: The Stratford General Hospital in Stratford, Ontario,
Canada. This 4-story hospital is approximately 50 years
old.
System: The 4" diameter cast iron rain leader for the
hospital. This vertical pipeline is 80 feet in length and
has two 90 degree elbows and two 45 degree elbows.
The pipes, located behind walls, run from the roof to the
cleanout in the basement kitchen.
Problem: The aged pipeline had a crack, which caused
water damage to drywall on the third floor. Cracks are
extremely common in roof drain pipes as a result of
weather conditions.
Circumvention: If the customer had chosen a traditional repair, such as a
repipe, the walls outside of this 4-story rain leader would have to be torn apart,
in order to access the pipes and then replace them. Patient rooms, surgical
rooms, laboratories and the kitchen would have to be closed and patients would
be moved for the duration of the work. After new pipes would be installed, a
drywall contractor would have to be hired to close up the walls, and then the
rooms would have to be thoroughly cleaned before moving patients back into
them. This would be a very disruptive, destructive and expensive process.
Solution: A repeat customer, Stratford General Hospital chose Nu Flow to
rehabilitate another failing rain leader, after the manager of facilities experienced
the durability and strength of our structural liners. To complete this project,
first, Nu Flow technicians set up an infection control and dust control tents in
the kitchen, to ensure sanitary conditions. Next, our proprietary "finger" drain
cleaning fools were used to remove heavy debris throughout the pipe system.
There was a 2" restriction of debris at the bottom of the pipe line, near the
clean out. After the pipes were returned to their original diameter, the Nu Drain
structural liner was prepared and installed. This epoxy-soaked liner was installed
using existing access points and patented Pull-in-Place technology, preventing
demolition to the building. The project was completed in less than two days and
did not cause any disruption to the hospital’s normal operations.
“What really sold me on Nu Flow’s
technology was when I talked to our
in-house plumbers and they told me
how strong the epoxy liner was.”
- Doug Biesinger, Facilities Manager,
Stratford General Hospital
