A. The applicant shall be responsible for all review costs in the case
of any sanitary sewer application for which the Department requires
professional assistance in making findings. If not previously established,
the applicant will deposit in an escrow account with the Township
the fees that the Township requires to review and advise on the application.
The initial escrow deposit shall be $2,500 to provide review and approval
of any sanitary-sewer-related items.
B. Any sanitary sewer collection system shall be adequate to handle
all present and probable future development. Alignments outside streets
shall require easements subject to the review and approval by the
Planning Board Attorney and Engineer and, thereafter, Municipal Attorney
and Engineer if such alignment involves municipal lands or interests.
C. Any changes in use of any existing property or facility or proposed
new construction shall be subject to review and reevaluation of the
sewer service and the amount of flow rights assigned by the Township.
Any increase shall subject the applicant to additional fees. Flow
rights are granted to the Township of Montville and other member communities
by the Parsippany-Troy Hills Sanitary Sewer Utility. By agreement,
the Township has been granted sewer flow rights for the municipality.
Flow rights available for purchase are finite and limited and assigned
upon purchase at time of sanitary sewer application. Flow rights are
not guaranteed. Therefore, all completed applications for sewer permits
shall be approved on a first-come-first-served basis. The obligation
of the Township to approve applications for sewer permits is contingent
upon the availability of capacity of both the Parsippany-Troy Hills
Sanitary Sewer Utility and the collection system infrastructure that
is owned and maintained by Parsippany and the Township of Montville.
If sufficient flow rights are not available from the Township of Montville,
it shall be the sole responsibility of the developer to acquire sufficient
flow rights to accommodate its development as follows: "If Montville
does not already possess adequate flow rights in order for the developer
to proceed with the development, Montville may, in its sole discretion,
choose to negotiate for the purchase of additional flow rights. The
developer must reimburse the Township of Montville for the cost of
such rights." Construction permits shall not be issued unless and
until the developer provides adequate evidence of its acquisition
of flow rights sufficient to serve the proposed development. The existing
sanitary sewer system for the development of two or more single-family
dwellings, multifamily residential, industrial and commercial users,
including the overall capacity of the any pump stations that will
serve the projects location, shall be adequate to handle the existing
flow and the projected flow, based on complete development of the
approved project. This shall be determined at the cost of the applicant.
D. When plans for future development in the service area necessitate
increased capacity, the Township may enter into an agreement with
the developer to address the fair share of the costs of improvements
required for the proposed development in accordance with the Municipal
Land Use Law (MLUL), specifically N.J.S.A. 40:55D-42.
(1)
The applicant's proportionate share of sewerage facilities,
including the installation, relocation or replacement of collector,
trunk and interceptor sewers, and appurtenances associated therewith,
shall be computed as follows:
(a)
The capacity and the design of the sanitary sewer system shall be based on the standards specified in Chapter
300 and in the NJDEP 7:14a.23.
(b)
If the existing system does not have adequate capacity to accommodate
the applicant's flow given existing and reasonably anticipated
peak hour flows, the pro rata share shall be computed as follows:
Developer's Cost\Total Cost of enlargement or improvement
|
=
|
Development generated gallons per day (gpd)\Capacity (gpd) of
enlargement or improvement
|
E. If a public sanitary sewer system will be provided to the area within
a six-year period as indicated in the municipal sewer master plan,
or other official document, the Township may require installation
of a capped system within the road right-of-way or existing municipal
easements to service the approved lots; or, alternatively, the Township
may require a performance guaranty in lieu of the improvement. Capped
sanitary sewers shall be allowed only in areas indicated for sewer
service in the State of New Jersey Statewide Water Quality Management
(WQM) Plans and where permitted by NJDEP through sewer connection
approval.
F. The applicant shall submit to the Township for review for compliance
with this article details of the planned pipes, joints, mains, laterals
and appurtenances. All materials used for sanitary sewer systems shall
be manufactured in the United States, wherever available, as governed

backfilling, all joints shall be filled with mortar and pointed to
form a dense hard joint. Thereafter, one coat of coal tar or asphaltic
pitch shall be applied to the surface of the manhole covering all
mortared joints, lift holes, etc.
(4) Brick collars. When necessary to bring the manhole
frame to proper grade, concrete brick collars shall be used. All brick
shall be thoroughly wet before laying and shall be laid in a full
bed and joint of mortar. Joints shall be 1/4 inch on the interior
face and shall be struck smooth with the interior face. Brick shall
be laid as headers with joints broken between courses, and finished
collar shall be plastered on the outside with cement mortar as shown
and thoroughly waterproofed with two coats of asphaltic paint. The
collar shall be completely sealed to prevent water intrusion. Brick
shall conform to the requirements of ASTM C32 Grade MA.
(5) Steps. Each manhole shall have drop-type aluminum
steps, projecting six inches into the manhole, and shall extend through
the wall. The steps shall be aluminum alloy 6061-T6 or equal as shown.
(6) Cover and frame. The manhole cover and frame shall
be Type #1203 as manufactured by Campbell Foundry Company. Manhole
cover shall be cast with the letters "MONTVILLE TOWNSHIP SANITARY
SEWER."
(7) Pipe to manhole connection. All pipe to manhole connections
shall be watertight flexible seals and shall meet Rubber Gasket Specifications
ASTM C-443 and Test Performance Requirements ASTM C-425 for compression
joints.
(8) Watertightness. Each manhole shall be absolutely watertight.
Manholes that are not watertight will not be accepted. Plastering
on top of defective joint to correct leaky conditions will not be
permitted.
Inspection and testing shall be performed by the Engineer to ensure compliance with the requirements of this Chapter
300 and Chapter
394 of the Township Code, approved plans and specifications and the manufacturers' recommendations.
A. Inspection.
(1) Inspection of the work will be conducted at all times
during construction. The contractor shall cooperate and assist in
the inspection of all work.
(2) The inspection of newly installed sewers shall be
done to detect and record any and all areas of improperly installed
pipe. Improperly installed pipe shall include those sections of pipe
that are broken, crushed, misaligned, deflected, or in any other way
damaged; in which case, the contractor shall be obligated to remove
said damaged section of pipe and make all necessary repairs and/or
replacement at the direction of and to the satisfaction of the Engineer,
to affect the proper operation and capacity of the sewer.
B. Testing.
(1) Infiltration.
(a)
All infiltration noticeable during construction,
whether an air exfiltration test has been performed or not, and judged
to be above the allowable by the Engineer, shall be stopped and corrected
immediately. Infiltration shall not exceed 50 gallons per inch of
pipe diameter per mile per 24 hours.
(b)
Rates of infiltration shall be determined by
means of V-notch weirs or pipe spigot in an approved manner and at
such times and locations as may be directed by the Engineer during
the progress and at the completion of the work.
(c)
Testing shall be conducted during the progress
of the work, at the time and over completed pipe sections as determined
by the Engineer. No test shall be accepted unless witnessed by the
Engineer or his authorized representative. Maximum length of test
sections shall be 2,000 feet. All visible leaks shall be made tight
and tests shall be repeated until the results are satisfactory.
(2) Deflection (polyvinyl chloride pipe only). After all
polyvinyl chloride pipe has been laid and trenches backfilled, a deflection
test shall be performed on each section of pipeline between manholes.
In cases where a fully circular pipe cross section cannot be viewed,
then a mandrel shall be passed through the section in question. The
mandrel shall be two times the pipe diameter in length and 90% of
the pipe diameter.
(3) Low pressure air exfiltration test.
(a)
After the pipe has been laid and backfilled,
a low-pressure air test shall be made on each section of pipe. Air
shall be slowly supplied to the unplugged section of pipe to be tested
until the internal air pressure reaches 4.0 psi greater than the average
backpressure of any groundwater that may submerge the pipe. At least
two minutes shall be allowed for temperature stabilization before
proceeding further. The backpressure of any groundwater caused by
the water head above the center line of the pipe must be determined
by a method approved by the Engineer. This backpressure must be added
to the standard test pressures to compensate for the groundwater effect
on the air test. Maximum length of test sections shall be 500 feet.
(b)
The rate of air loss shall then be determined
by measuring the time interval required for the internal pressure
to decrease from 3.5 psi to 2.5 psi greater than the average back
pressure of any groundwater that may submerge the pipe.
(c)
The pipeline shall be considered acceptable
when the time interval for the 1.0 psi pressure drop is not less than
the holding time required by the Engineer.
(d)
If the pipe installation fails to meet these
requirements, the contractor shall repair or replace all defective
materials or workmanship. The complete pipe installation shall meet
the requirements of this test.
Where sewer service is requested by any commercial
or industrial establishment or by any institution, such as a school,
hospital, nursing home and the like, the applicant shall provide engineering
drawings and specifications to be reviewed by the Engineer. The applicant
shall obtain all required permits and approval and shall have full
financial responsibility for installation of the sewer service.
Extensions to or changes in the public sewer
system may be initiated by the governing body by petition from property
owners, or by application from a real estate developer. If such extension
or change is deemed advisable by the governing body, it shall prescribe
the terms and conditions under which the extension shall be made and
shall require written acceptance thereof by the petitioners or applicant.
No person shall discharge or cause to be discharged
any stormwater, surface water, groundwater, roof runoff, subsurface
drainage, cooling water or unpolluted industrial process water into
any public or private sanitary sewer system or individual sanitary
sewage disposal facility.
Stormwater, cooling water and all other unpolluted
process water or drainage shall be discharged to such sewers as are
specifically designated as storm sewers or to a natural outlet approved
by the Health Officer.
All discharges to the Township public sanitary
sewer system shall be in conformance with the discharge requirements
of the Parsippany-Troy Hills Sewer Utility. Except as hereinafter
