Roosevelt Avenue Pump Station Force Main
Recommended Course of Action
Background
MEMO
The Borough of Carteret (the Borough) owns and maintains the Roosevelt Avenue Pump
Station force main, which is 27 -inch diameter prestressed concrete cylinder pipe (PCCP) force
main with a total length of approximately 16,000 linear feet (or approximately 3 miles). The
force main conveys the Borough's wastewater to the Middlesex County Utilities Authority
(MCUA) for treatment. The force main was constructed in 1989 during the construction of the
Roosevelt Avenue Pump Station and decommissioning of the Wastewater Treatment Plant that
the Borough once owned and operated.
The Roosevelt Avenue Pump Station is the Borough's main pump station and is the most
critical pump station in the system since it receives all of the wastewater generated and
collected within the Borough. Due to the critical nature of this wastewater infrastructure, the
station and the force main must remain in continuous service. The Roosevelt Avenue Pump
Station contains three pumps, each rated for 4,600 GPM (6.625 MGD). The station reportedly
does not typically operate with just one pump. Its typical flow rate with two of the three pumps
operating is approximately 6,945 GPM (10 MGD).
The 27 -inch diameter force main is constructed of PCCP that was installed over 25 years ago.
PCCP pipe relies on the prestressed wires wrapped around the steel cylinder and concrete
coatings of the pipe to provide much of the pipe's strength. Historically, a certain grade of metal
wire was used in the pipe manufacture which has now resulted in a failure mode called
embrittlement. This pipe with this type of wire was only manufactured for a few years. Although
most PCCP pipe is speculated to have a service life in excess of 50 years, certain vintages of
PCCP have been known to fail dramatically due to the wire failure. The Borough's 27 -inch
PCCP force main has experienced failures in the past several years with the most recent prior
failure occurring in 2014. At that time, a pin -hole leak was identified in the force main. However,
it was not determined what caused the exact mode of failure although hydrogen sulfide is
suspected.
Force Main Failure Location
A force main leak / failure was discovered on or about November 22, 2016 in the backyard of a
private residence at 11 Ned Court in Woodbridge Township. This section of the force main is at
the downstream end of the overall alignment and is approximately 1,300 linear feet from the
point where the force main discharges and connects to a gravity sewer. At the failure location
(referenced as Station 16 +80), the force main traverses through a 15 -foot wide permanent
sanitary sewer easement through the residential property. The location of the leak is at a higher

elevation as compared to the gravity sewer and if the Roosevelt Ave PS shuts off during night
time low flows there is the potential that this section of pipeline could be exposed to air, which
can result in internal corrosion.
Force Main Failure Mode
The mode of failure is anticipated to be along the top of the force main pipe due to hydrogen
sulfide corrosion of the internal concrete core and inner steel cylinder pipe. Once a pin hole
develops through the steel cylinder it will push through the outer wire wraps and concrete layer.
Based upon our knowledge and prior experience evaluating and designing repairs and
rehabilitation of this type of force main, it is suspected that hydrogen sulfide is present in the
force main especially at the end of the force main where the travel time is longest. At the high
points, it is suspected that hydrogen sulfide gas pockets are forming and possibly extending for
hundreds of feet. During normal flow conditions, it is likely that the force main is fully
pressurized to the end. However, when the pump station is operating at minimum flows, it is
suspected that the force main operates as a pressurized full -pipe upstream of the alignment's
high point, which is located within the PSE &G easement (Station 18 +60), but downstream of
the high point, the force main could operate under gravity flow conditions. At the high point
location, there is an air release valve in a manhole structure. Further downstream of this
location along Wesley Place (Station 7 +80), there is a second local high point and air release
manhole. It has not been determined if the air release valves are functioning properly, which
would vent out the hydrogen sulfide gas. We understand that the at least one of the air release
valves has been taken offline.
It is anticipated that there could be additional hydrogen sulfide corrosion damage on either side
of the two high points. Based on a review of the force main profile on the design plans (note
that no record plans are available), the area of concern is between Station 5 +75 and Station
10 +50 at which point the top of the pipe is above the invert elevation of 13.30 at the high point
at Station 7 +80. The other area of concern between Station 16 +25 and Station 22 +00 at which
point the top of the pipe is above the invert elevation of 14.00 at the high point at Station
18 +60.
Short -Term Provisions Taken by Borough
It has been observed that while the pump station operates with only a single pump, there have
been no sewage discharges observed at 11 Ned Court. We suspect that under a single pump
operation the force main is not pressurized at the leak location or is only leaking minimally into
the soil. It is suspected that, if it becomes necessary to operate the station at full capacity (with
two or three pumps in service), the force main would operate under pressure for the entire
alignment and it would likely exacerbate the leak at the identified location.
The Borough is required to report the discharge to NJDEP in accordance with State
regulations. It is understood that the Borough contacted NJDEP on November 23, 2016 to
report the discharge and a case number was assigned.

Recommended Course of Action
The overall plan for the Borough to address this leak and this section of the force main is a
four -step process:
1. Prepare an access point to the force main to allow for internal inspection.
2. Perform an internal pipe inspection. Investigate the affected area to determine if
the leak is due to internal corrosion or a wire failure. If the leak is due to internal
corrosion, determine if it limited to a specific defined area (5 -10 feet) or is the
length of damaged pipe more extensive.
After assessing the type and extent of pipe damage, select a method of repair or
replacement. Options available include a spot replacement with 10 to 20 feet of
pipe, CIPP lining of greater distances 300 to 500 feet, full replacement in the same
alignment, full replacement in an alternate alignment.
3. Step up the appropriate bypass system to facilitate the selected repair.
4. Perform the repair.
The four steps are explained in further detail below:
Step 1 — Force Main Pre - Inspection
The Borough has engaged their on -call utility repair contractor (B &W Construction) to cordon
off the area around the leak and to prepare for the internal force main inspection. The proposed
inspection procedure and equipment will require a 20 -inch diameter opening to gain access to
the force main. Each air release manhole consists of a 27 -inch by 24 -inch tee with a tapped
blind flange that is connected to the air release valve. The contractor's investigative and
preparation work over the next week should include the following:
• Pumping groundwater out the air release manholes;
• Inspecting the 24" blind flange and air release valve on the 27" by 24" tee;
• Preparing for the removal and replacement of the 24" blind flange flange by replacing
every nut and bolt on the blind flange; and
• Preparing the manhole structure to ensure the opening is a minimum of 20" for the
insertion of the inspection equipment. This may require removal of the top slab or cone
section of the chamber.
Step 2 — Force Main Inspection
It is recommended that the Borough conduct an internal inspection of the force main prior to
taking any measures to install bypass piping. This step is critical for a number of reasons:
M

MACDONALD
To John DuPont, PE, PP, CME

Page 4 of 5
• The interior of the force main must be inspected to determine if the proposed location
of the line -stop valve (for bypassing) will be suitable and will provide for a complete
seal of the pipe;
• The interior condition of the force main must be inspected to determine the extent of
corrosion and understand the extent of rehabilitation and /or replacement work
necessary;
• Although the suspected cause of failure is internal corrosion cause by hydrogen sulfide,
the overall condition of the force main should be inspected to ensure there are no
issues with the prestressing wire; and
• The actual location (horizontal & vertical alignments) of the force main must be
confirmed since no record plans exist for the force main.
For this effort, we will utilize a specialty subconsultant for the internal inspection utilizing their
an internal crawler system. This system is an advanced, remotely operated robotic crawler with
a modular -based set up that allows it to be equipped with multiple tools needed for pipe
inspection. For this inspection, the system will be provided with the following capabilities:
• High definition digital pan - tilt -zoom closed circuit television (CCTV) for live video
stream of the pipeline during the inspection effort;
• High speed pipe - profiling SONAR to measure the pipeline's size, shape and level of
corrosion. This process is performed on submerged areas of the force main; and
• Geographic mapping using modular high end inertial measurement unit to allow the
force main to be marked out and the depth of the pipe to be determined.
This inspection will be performed at night during low flows when the pump station can be taken
out of service. It is currently anticipated that this inspection can be performed within a 3 to 4
hour shut -down window.
The CCTV data will be viewable during the actual inspection work. The results of laser /sonar
profiling may take 2 to 3 days to convert the digital data into a footprint of the surface profile of
the pipeline. (An example of the data to be retrieved is attached).
After understanding the pipe condition and extent of pipe damage, a final decision can be made
with regards to the most effective type of repair and the extent of bypassing required.
Step 3 — Line -Stop Valve Installation and Temporary Bypass Pipe Installation
After the selection of the repair method a temporary bypass scheme will be developed. A line
stop will be installed to temporarily stop flow and isolate the downstream section of the force
main. After the line stop is installed, the bypass piping would then be installed. For this
application, we recommend considering a line stop with an integrated bypass housing.

Once the line -stop valve is in place, the bypass piping can be installed. The bypass piping
would be temporary HDPE or fusible PVC piping installed on the ground surface with provisions
to ensure proper thrust restraint and adequate protection.
If a full bypass is required, the temporary bypass piping alignment would extend from the
connection to the existing force main and through the PSE &G property (Block 666, Lot 23.02)
to Port Reading Avenue (Middlesex County Road 604). The temporary main would then be
installed along Port Reading Avenue to the intersection with Old Road and onto New Jersey
Turnpike Authority (NJTA) right -of -way. It would traverse the NJTA right -of -way to the manhole
where the flow transitions to gravity flow, which is located on Wesley Place. The total length of
the bypass piping would be approximately 3,325 feet. A temporary easement will be required
through PSE &G property (Block 666, Lot 23.02). Also, approvals will be required from
Middlesex County Engineering for the installation of the temporary piping through the Port
Reading Avenue right -of -way. Additionally, approval would be required from NJTA and a
license to cross agreement may be required for installation of the temporary bypass piping
within the NJTA right -of -way. It is recommended that the Borough engage these entities
(PSE &G, NJTA and Middlesex County) as early as possible as their approvals will be critical.
Alternate bypass piping schemes may be considered based on the final selected repair
approach.
Step 4 — Force Main Rehabilitation or Repair
As recommended in step 2, the Borough will undertake the repair, in -situ rehabilitation or
replacement of sections of the force main.
Budgetary Estimate
It is understood that the Borough intends to authorize emergency funding to undertake the
necessary repairs to the force main. Step 1 and Step 3 outlined herein will be performed
primarily by B &H Contracting with support from the Borough and potentially other specialty
subcontractors. Step 2 will be performed by Mott MacDonald with support from a specialty
subconsultant who will conduct the inspection. For budgetary purposes, the Borough should
plan to budget $60,000 to perform Step 2. Following the completion of this step, we will provide
the Borough with a report summarizing the findings and provide recommendations for the
proposed repairs to be performed under Step 4.
