[Amended 4-8-2015 by L.L.
No. 2-2015]
G. Independent building sewers. A separate and independent
building sewer shall be provided for every building, except that where
one building stands at the rear of another on an interior lot and
no private building sewer is available or can be constructed to the
rear building through an adjoining alley, court, yard or driveway,
the building sewer for the front building may be extended to the rear
building.
H. Existing building sewers. Old building sewers may
be used in connection with new buildings only when they are found,
on examination and testing by the Superintendent, to meet all requirements
of this chapter.
I. Materials. The building sewer shall be cast-iron soil
pipe, ASTM Specification A-74 (latest revision thereof), or PVC nonpressure
pipe, ASTM Specification D-3033 with minimum SDR of 41, or nonpressure
PVC pipe labeled "Schedule 40," ASTM Specification D-2665 and D-1785.
All joints shall be compression-type joints with neoprene or rubber
circular gaskets. Chemically welded joints shall not be allowed. For
buildings requiring pumping, the discharge pipe shall be PVC or HDPE
pressure pipe, AWWA Specification C-900 (latest revision thereof)
with minimum SDR of 18 or such a material as is approved by the Superintendent.
All pressure pipe shall have a working pressure of 150 pounds per
square inch.
J. Separation. Sewers shall be laid at least 10 feet
horizontally from any existing or proposed water main. The distance
shall be measured edge to edge. In cases where it is not practical
to maintain a ten-foot separation, the appropriate reviewing agency
may allow deviation on a case-by-case basis. Such deviation may allow
installation of the sewer closer to the water main, provided that
the water main is in a separate trench or on an undisturbed earth
shelf located on one side of the sewer and at an elevation so the
bottom of the water main is at least 18 inches above the top of the
sewer. In cases where this criteria cannot be accomplished, the Superintendent
will determine if other suitable protection can be obtained.
K. Approval. No building sewer shall be covered until
after it has been inspected, tested and approved by the Superintendent.
L. Testing. All building sewers (gravity and/or pressure)
shall be tested for leakage after installation. The tests shall be
conducted on all joints in a pressure sewer and all joints subject
that would be exposed to infiltration of groundwater, surface water
or other extraneous sources of nonpolluted waters on a gravity sewer.
The test shall be witnessed by the Superintendent or his authorized
representative.
(1) The test for a gravity sewer shall be conducted from
the trap and vent or grinder unit to the building plumbing system.
The sewers shall be charged with air to four pounds per square inch
pressure. The sewer shall show a loss of pressure no greater than
0.5 pound per square inch over a ten-minute period.
(2) A two-hour leakage test shall be conducted on all
pressure pipe and joints between the grinder unit and the point of
connection to the POTW.
(a)
The line shall be filled with water, with all
air expelled and pressurized to 100 pounds per square inch, based
on the elevation of the lowest point in the line under test and corrected
to the elevation of the test gauge.
(b)
The leakage under the conditions of the test
for force main shall be determined by the following formula:
|
L
|
=
|
ND√P
7400
|
|
Where
|
|
L
|
=
|
Allowable leakage in gallons per hour
|
|
N
|
=
|
Number of joints in the length of pipeline tested
|
|
D
|
=
|
Nominal diameter of pipe in inches
|
|
P

=
|
Average pressure during the leakage test, in
pounds per square inch gauge
|
M. Replacement. In certain cases where the building sewer
is being replaced, the Superintendent may allow the use of high-density
polyethylene pipe inside of the existing building sewer. Joints shall
be by a coupling acceptable to the Superintendent. Express permission
of the Superintendent shall be obtained prior to proceeding with this
type of installation. Application for permission shall be accompanied
by a plan and a list of materials, sizes and depths.
N. Installation. All gravity building sewer shall be
bedded to one foot above the top of pipe and six inches below invert
of the pipe. The bedding material shall be sand or stone of a maximum
dimension of 1/2 inch and shall be placed to eliminate voids between
the pipe and the undisturbed soil. If the soil conditions appear unstable,
the Superintendent may require more exacting methods of support for
the pipe.
O. Size and slope.
(1) The size, slope and alignment of the building sewer
shall be subject to approval of the Superintendent, but in no event
shall the diameter be less than as follows:
[Amended 4-8-2015 by L.L.
No. 2-2015]
(a) Residential: four inches.
(2) Grade or slope for various pipe sizes shall be not
less than:
(a)
Four-inch pipe: 1/8 inch per foot.
(b)
Six-inch pipe: 1/16 inch per foot.
(c)
Over six inches: plan required for engineering
review.
P. Depth and alignment. The depth of the building sewer
shall be sufficient to afford protection from freezing and against
physical damage and shall not be less than three feet from the surface.
The building sewer shall be laid at a uniform grade. The line shall
be straight or laid with properly curved pipe and fittings. Changes
in alignment direction greater than 45º shall be provided with
cleanouts accessible for cleaning.
Q. Depth at building. No building sewer shall be constructed
to permit flow from a basement drain to the Town's sanitary sewer
lines. All building connections shall be a minimum of three feet above
grade of floor or basement level. A variance from the three-foot minimum
will be considered on an individual basis upon written request and
written waiver by the Superintendent.
R. Inaccessible gravity connections. In all buildings
in which any building sewer is too low to permit gravity flow to the
public sewer, sanitary sewage carried by such sewer shall be lifted
by a method approved by the Superintendent and discharged to the public
sanitary sewer at the expense of the owner.
S. Illicit connections. No person shall permit the connection
of roof downspouts, foundation drains, areaway drains, or other sources
of surface runoff or groundwater to a building sewer which in turn
is connected directly or indirectly to the public sanitary sewer.
T. Connection restriction. No building sewer shall be
connected to the public sewer if the building which it is to serve
is not totally enclosed and all excavations for said building are
backfilled and restored to a finished grade.
U. Relocation
of inflow and infiltration.
[Added 6-9-2011 by L.L. No. 1-2011]
(1) Notwithstanding
any of the provisions of this chapter, the Town, at District expense,
may install or cause to be installed A clamps and related work on
sewer residential service externals where:
(a) Such laterals were installed prior to the requirement for the use
of A clamps by Town regulations; and
(b) The Town is acting pursuant to a program for redaction of inflow
and infiltration by order of the Town Board, and such lines have been
identified by the Superintendent for inclusion in such program; and
(c) Property owners have granted the Town access and executed any required
agreements.
(2) Nothing in this Subsection
U shall relieve the residential property owner from the obligation, at the owner's expense, to prevent inflow and infiltration through its service lateral or to maintain and repair or replace service laterals, including, but not limited to, the installation of A clamps when necessary.
V. Traps and vents. No building sewer shall be connected to the public
sewer if the building which it is to serve is not installed with a
sanitary sewer trap and vent at the right-of-way or as approved by
the Superintendent.
