The sewer regulations of Nassau County shall
govern the discharge of all objectionable wastes into the public sewer
system.
A.
Corrosive or harmful wastes and wastes at a temperature
higher than 140º F. shall not be discharged into a plumbing system
to which water closets, bathtubs, lavatories or other household plumbing
fixtures are connected. The plumbing system designed to receive such
wastes shall be of material capable of resisting the destructive action
of such wastes.
B.
Where fixtures discharge wastes at a temperature higher
than 140º F. they shall be provided with a satisfactory cooling
device.
A.
No explosive or flammable matters shall be discharged
into any sewer.
B.
Cleaning establishments, buildings used for housing
or repairing automobiles, gasoline and oil service stations and other
buildings or establishments where gasoline, oils, calcium carbide
or other explosives or flammable materials are stored, sold or handled,
the drains from which are connected to the public sewer, must be provided
with an approved intercepting pit or tank so constructed, located
and maintained as to prevent the entrance into the sewer of such explosive
or flammable matter.
A.
Independent system. The drainage and plumbing system
of each new building and of new work installed in an existing building
shall be separate from and independent of that of any other building,
except as provided below, and every building shall have an independent
connection with a public or private sewer when available.
B.
Exception. When one building stands in rear of another
building on a interior lot and no private sewer is available or can
be constructed to the rear building through an adjoining alley, courtyard
or driveway, the house sewer from the front building may be extended
to the rear building, and the whole shall be considered as one house
sewer.
Old drains may be used in connection with new
buildings or new plumbing only when they are found, on examination
and test, to conform in all respects to the requirements governing
new drains, as prescribed in this chapter. If the old work is found
defective, the Plumbing Inspector shall notify the owner to make the
necessary changes to conform to this chapter.
Every new building must have its sewer connection
directly in front of the building, unless permission is otherwise
granted by the Plumbing Inspector.
After an owner has been notified that the lateral
sewer line available to his or her building has been completed and
is ready for use, he or she may apply for a permit from the county
and the village to connect thereto. After such notice has been given,
only one permit for the cleaning of existing cesspools shall be granted.
When a building is connected to the county sewer system, all cesspools
and septic tanks on the said property shall be cleaned out, disinfected
and properly and completely backfilled with clean fill.
A.
Type and size of pipe. The sewer connection to a building
shall be of extra-heavy cast-iron sewer pipe, asbestos cement sewer
pipe or bituminized-fibre pipe CS 116-54, United States Government
Department of Commerce. All of the aforesaid pipe shall not be less
than five inches in diameter. Where the ground is made or filled in
or where the pipes are less than three feet below ground level or
in any case where there is danger of settlement by frost or from any
other cause, the sewer connection to a building must be of extra-heavy
cast-iron pipe with joints caulked with either molten lead or other
joint compound approved by the Board of Public Safety.
B.
Fittings, connections and cleanouts. All fittings
and couplings shall be in accordance with and conform to existing
ASTM specifications for cast-iron pipe, A74-72, or federal specifications
SS-P-351 of the United States Government Department of Commerce CS
116-54. When there is a change of direction of the sewer line over
a forty-five-degree angle, a cleanout shall be inserted after the
bend, and such cleanout shall extend to the surface of the ground
and be properly capped. Using a series of smaller bends to make a
change of direction shall not do away with the use of the cleanout.
C.
Laying of pipe. No pipe shall be laid in any trench
unless the sewer connection to the building and the connection to
the sewer at the curb are exposed. All pipe shall be laid with a uniform
fall and in as direct and straight a line as possible from two feet
outside the outer face of the building wall or point where existing
cast-iron pipe extends through the wall to the existing connection
to the sewer at the curb. The minimum fall per foot of pipe laid shall
be 1/4 inch, except that a fall of 1/8 inch per foot may be allowed
upon specific approval of the Plumbing Inspector where a fall of 1/4
inch shall be impossible. Sewer piping shall be supported throughout
its entire length.
D.
Tunneling. Tunneling may be done in yards, courts
or driveways of any building site, provided that cast-iron pipe is
used. However, the diameter of the tunnel may not be over twice the
diameter of the pipe, and it shall be of such length as will permit
inspection of all joints. All tunnels shall be backfilled by the use
of water.
E.
Backfilling. Adequate precaution shall be taken to
ensure proper compaction of backfill around pipe without damage to
piping. Trenches shall be backfilled in thin layers to 12 inches above
the top of the pipe with clean earth which shall not contain stones,
boulders, cinder fill or other materials which will damage or break
the pipe or cause corrosive action. Mechanical devices may then be
used to finish backfilling to grade. All trenches shall be compacted
with water.
F.
Joints and connections. Joints and connections in
the sewer connection to a building shall be root-proof, gastight and
watertight so as to withstand the pressure imposed on the joint in
case of stoppage. Cast-iron bell-and-spigot may be caulked with either
molten lead or other joint compound approved by the Board of Public
Safety. Caulked joints for cast-iron bell-and-spigot soil pipe shall
be firmly packed with oakum or hemp and filled with molten lead or
other approved joint compound not less than one inch deep and not
to extend more than 1/8 inch below rim of hub. No paint, varnish or
other coating shall be permitted on the jointing material until after
the joint has been inspected. If other than lead compound, approved
as above-mentioned, is used, the joint shall be made in accordance
with manufacturer's specifications. Joints in asbestos cement sewer
pipe shall be made with sleeve couplings of the same composition as
the pipe, sealed with rubber or other approved rings. Joints between
asbestos cement sewer pipe and extra-heavy cast-iron pipe or joints
between either of the aforementioned pipes and the county spur shall
be made with the proper fittings as specified in existing federal
specifications published by the Federal Specifications Board.
G.
Location of sewer connection to a building. The sewer
connection to a building shall have a horizontal or lateral separation
of at least seven feet or a vertical separation of at least two feet
and shall be located below the water service. In the event that any
of the above minimum separations are not possible, permission must
be obtained from the Plumbing Inspector to vary the above requirements,
and the Plumbing Inspector's decision as to location and type of pipe
to be used shall be followed.
H.
Damage to village property. The plumber making the
sewer connection to a building shall be responsible for any damage
to village property, including but not limited to sidewalks, aprons,
trees, grass area and curbs. He or she shall take all precautions
necessary to protect village property. Any open trench or other obstruction
in, on or abutting the sidewalk, street or other village property
shall be surrounded by suitable barriers or guards for protection
of persons using the streets or property in the daytime and, in addition
thereto, by lights or flares from twilight continuously until daylight.
Such barriers and lights shall conform, in kind and number, to the
requirements of the Plumbing Inspector. Immediately upon the approved
inspection of the sewer connection to a building, the plumber shall
see that all trench settlement is properly filled to the grade of
the original ground.
I.
Inspections required. The Plumbing Inspector shall
be notified 24 hours in advance of the starting of work under any
permit issued hereunder and shall be further notified before 10:00
a.m. of the day an inspection is required. The following inspections
are required under this chapter:
(1)
First inspection. The first inspection shall be made
when the pipe is laid and joints are made but before any backfill
is placed on the pipe.
(2)
Second inspection. The second inspection shall be
made when the cesspool or septic tank is cleaned but prior to backfilling.
(3)
Third inspection. The third inspection shall be the
final inspection and shall be made when the sewer connections to a
building are complete.
