A.
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.
When one building stands in the rear of another building
on an 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 will 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 code. If the old work is found defective,
the proper administrative authority shall notify the owner to make
the necessary changes to conform with this code.
Every new building must have its sewer connection
directly in front of the building unless permission is otherwise granted
by the Building Inspector.
A.
After an owner has been notified that the lateral
sewer line available to his building has been completed and is ready
for use, he may apply for a permit from the county and village to
connect thereto. After such notice has been given, permits for the
cleaning of existing cesspools will be granted. When a building is
connected to the county sewer system, all cesspools on said property
shall be cleaned out, disinfected and properly and completely backfilled
with clean fill.
B.
When a septic tank and/or cesspool is being discontinued,
the house sewer may be connected at the inlet of the septic tank and/or
cesspool.
C.
Where a house sewer is connected at the point of entry
to a septic tank and/or cesspool, connection must be made by bridging
with one length of extra-heavy ductile iron pipe. Pipe must be properly
supported at wall with open space above same to prevent damage to
joints in the event that the septic tank and/or cesspool settles.[1]
[Amended 8-12-1974 by L.L. No. 7-1974[1]]
The sewer connection to a building shall comply
with all the regulations of the County of Nassau, Department of Public
Works, Division of Sanitation and Water Supply.[2]
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 1/8 inch
per foot. Sewer piping shall be supported throughout its entire length.
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 outside the tunnel. All tunnels shall be backfilled by
the use of water.
[Amended 8-12-1974 by L.L. No. 7-1974]
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, cinderfill 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, using the jetting method.[1]
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 Building Inspector
to vary the above requirements, and his decision as to location and
type of pipe to be used shall be followed.
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 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 Building 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.
[Added 8-12-1974 by L.L. No. 7-1974]
All excavations for a sewer connection exceeding
the depth of five feet shall be properly shored with plywood or sheathing
material so as not to cause wholesale cave-in of the trench and surrounding
area.
The Building 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 article
and may be performed simultaneously.
A.
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.
B.
Second inspection. The second inspection shall be
made when the cesspool or cesspools are cleaned but prior to backfilling.
