A. General.
(1) When connection is to be made to an existing building sewer, such
connection must be made on the building side of the septic tank/cesspool
serving the building. This connection shall be made as close as possible
to the building. No cap, stopper or plug on the sewer system shall
be removed or punctured until permission has been granted by the Plumbing
Inspector.
(2) The contractor shall determine the difference in grade between the
points of connection. Under no circumstances is the trench to be dug
before it is determined that the minimum fall can be obtained.
(a)
If a minimum grade of 1/4 inch per foot or a maximum grade of
one inch per foot can be obtained, the contractor may proceed.
(b)
If the minimum grade is calculated to be less than 1/4 inch
per foot, but at least 1/8 inch per foot, the building sewer can be
installed; provided, however, that the pipe grade must be checked
during the installation with a transit. The contractor shall, if requested
to by the Plumbing Inspector, demonstrate that the pipe grade is at
least 1/8 inch per foot.
(c)
If the grade is calculated to be in excess of one inch per foot,
the building sewer shall be installed beginning from the building
at a grade of not less than 1/4 inch per foot nor more than one inch
per foot until the last portion of the building sewer, at which point
the building sewer pipe shall be angled down, utilizing pipe fittings,
to its connection point with the lateral.
(3) No portion of any sanitary sewer lateral or building sewer shall
be used until tested and approved in accordance with the provisions
of this article.

buildings must be approved by the Township Engineer.
(4) A minimum cover of three feet of earth shall be provided to protect
pipe from frost action and/or surface loading. Concrete encasement
shall be provided where cover is less. All changes in grade and alignment
(direction) shall be made with pipe fittings. No fittings exceeding
45° will be permitted except in the construction of the building
trap.
(5) Pipe transitions.
(a)
For the building sewer, no transition from one pipe size to
another or from one pipe material to another may be made without the
use of a gasketed solid wall transition coupling, Fernco Strong Back
(RC) coupling, or equivalent transition adapter fitting, manufactured
and designed for that purpose. Equivalent adapters must be approved
by the Township. No mortar or portland cement joints are permitted.
(b)
For the lateral sewer, no transition from one pipe size to another
or from one pipe material to another may be made without the use of
a gasketed solid wall transition coupling.
(6) All connections to the sewer system must be made into the lateral
provided for that purpose.
(7) Whenever the existing lateral is broken, the broken end must be cut
square and fitted with a duplex coupling or that section of pipe must
be replaced.
(8) Each connection must be made to the sewer within the property lines
of the lot or property. Building sewers shall be laid at a minimum
of five feet from side property lines.

the sewer main. A double sweep tee fitting may be used to facilitate
cleaning in each direction.
(g)
All cleanouts shall be capped with a watertight PVC screw-type

through the septic tank or cesspool, provided that the septic tank
or cesspool is pumped out, has holes punched in the bottom or the
bottom demolished, and is backfilled with 2B stone which has been
thoroughly compacted.
(2) The contractor shall have sufficient pumping equipment ready for
use at all times on the site. All groundwater which may be found in
the trenches and any other water which may get into them from any
cause whatsoever shall be pumped or bailed out so that the trench
shall be dry during pipe laying and backfilling. Water shall be kept
away from any mortar or concrete work until it has thoroughly set.
When water is encountered, no less than six inches of No. 2B stone
shall be used for the bedding for the pipe. No groundwater or surface
water shall be allowed to enter the sewer system. If, for any reason,
construction of the building sewer is delayed or stopped, the pipe
connected to the sewer main must be capped with a watertight plug.
(3) Ductile iron pipe shall be used under all driveways and/or parking
areas with the exception that if the crown of the sewer is greater

shall consist of a minimum of six inches of 2B stone under the pipe.
The bedding shall extend up to or beyond the midpoint of the pipe.
(3) Regardless of the type of pipe used, unsuitable material encountered
in excavation, such as ashes, muck and unstable soil, shall be removed
from the site and shall not be placed in the backfill. When the bottom
of the trench has been dug too deep, it shall be refilled to subgrade
with 2B stone.
F. Backfilling.
(1) Upon completion of the building sewer and/or lateral installation,
the trench shall be backfilled with 2B stone to a height of at least
six inches above the pipe. Care shall be exercised not to disturb
the pipe.
(2) The remainder of the backfill material shall be free from cinders,
ashes, refuse, vegetable or organic material or other material which,
in the opinion of the Plumbing Inspector, is unsuitable. Backfill
material containing stones up to six inches in greatest dimension
may be used. All stones or rocks in excess of six inches in greatest
dimension shall be removed. The trench shall be completely backfilled
without displacement of the grade or alignment of the building sewer.
Backfill material shall be free of ice, and no partially open trench
shall be permitted to be left open during the night when temperatures
below 32° F. are predicted.

(1) Use of the new building sewer shall not be permitted until the connection
has been inspected, tested and approved in accordance with procedures
set forth in this article.
(2) No use of the sewer system will be permitted until the collection
system, pumping facilities and treatment plant are ready to accept
sanitary sewage for disposal.

the cleanout at the right-of-way or easement and the building, shall
be the responsibility of the person, firm or corporation owning the
property.

installation has been approved.
[Amended 12-16-2014 by Ord. No. 129-G-2014]
A. Air testing.
(1) The Plumbing Inspector shall witness an air test of the building
sewer and lateral. Both ends of the sewer shall remain uncovered until
the air testing has been completed and the installation approved.
The air test shall be conducted by the building sewer contractor under
the direction of the Plumbing Inspector.
(2) The air test shall be made by attaching an air compressor to any
suitable opening and closing all other inlets and outlets to the system,
then forcing air into the system until there is a uniform pressure
of 5 psi on the entire system. This pressure shall be maintained for
four minutes with no more than a pressure drop of 0.5 psi. If this
requirement cannot be met, the leak shall be located and the building
sewer and lateral retested.
B. Water test.
(1) The Plumbing Inspector shall witness a water test of the building
sewer. The water test shall be conducted by the building sewer contractor
under the direction of the Plumbing Inspector and made at the expense
of the property owner.
(2) The water test shall be made by installing all cleanout and/or vent
riser pipes and by plugging the building sewer at the cleanout at
the edge of the right-of-way or easement. The risers and building
sewer are then filled with water. If there is no drop in water level
after 15 minutes, the building sewer is deemed acceptable. If the
level drops, the leak shall be located and repaired and the building
sewer retested.
