The size, slope, alignment, materials of construction
of a building sewer, the methods to be used in excavation, placement
of pipe, jointing, testing and backfilling the trench, and the connection
of the building sewer to the public sewer shall conform to all of
the requirements of the Uniform Construction Code, the plumbing subcode
of the State of New Jersey, this chapter and any and all other applicable
rules and regulations of the Borough. In the event of any inconsistency
in provisions of this section and the plumbing subcode, the plumbing
subcode shall control.
All service laterals and building sewers shall
be constructed of pipe materials permitted in accordance with the
provisions of the plumbing subcode of the State of New Jersey, and
jointing materials for the various types of pipe shall also conform
to the plumbing subcode.
Building sewer support shall be provided as
specified in the plumbing subcode of the State of New Jersey.
Where an improved property, at the time of securing
a permit to connect to a sewer, shall be served by a private sewage
disposal system, the existing building sewer line shall be disconnected
on the structure side of such private sewage disposal system and attachment
shall be made, with proper fittings, to continue such building sewer
line, undiminished in inside diameter but not less than four inches,
to the service lateral.
Fittings in a building sewer shall conform to
the type of pipe used in construction.
A. Horizontal changes in direction in a building sewer
must be made by use of "Y" branches or of 1/8 or 1/16 bends. Caulking
of lead joints or alignment of self-sealing joints to angles of less
than one over one (1/1) bend equivalent only shall be permitted.
B. The building sewer shall be laid as nearly as possible
in a straight line.
Fittings or connections in a building sewer
which have an enlargement, chamber or recess with a ledge, shoulder,
or reduction of pipe area that tend to obstruct the flow of sewage
shall not be permitted.
Leaded joints in cast-iron soil pipe in a building
sewer shall be packed with oakum in the bell and spigot terminations
and thereafter shall be filled with molten lead to a depth of at least
one inch and shall not be depressed more than 1/8 inch below the rim
of the hub. The lead must then be caulked in place. No paint, varnish,
or other coating shall be permitted on the jointing material until
after the building sewer has been tested and approved as provided
herein.
Floor drains shall be connected to a building
drain only with the approval of the proper administrative authority.
A cleanout shall be provided inside a building
in order to service a building sewer. In the event it is physically
impossible to locate a cleanout within the interior of a building,
said cleanout may be located immediately adjacent to the outside building
wall with the riser brought to the level of ground surface. Cleanouts
shall be provided on each building sewer and at intervals to permit
complete servicing with a fifty-foot long auger or tape. Cleanouts
shall be constructed by suing a "Y" fitting in the run of pipe with
a forty-five-degree bend and riser to the ground surface. The riser
pipe must be fitted with a standard four-inch screw type ferrule.
A "T" fitting with a riser to the surface of the ground, with a cap
clamped in place, shall be installed in all building sewers at the
curbline at the point of connection to the sewer service lateral or
at any location within the sidewalk area. Inside cleanouts shall be
located at a minimum height of six inches above the basement floor.
Whenever, in the opinion of the Borough Engineer
or the authorized agent, the trenching conditions require either a
specific type of pipe, jointing material or encasement in concrete,
such materials shall be installed to protect the owner and/or the
Borough as follows:
A. Where the trench is over 12 feet deep, RCP pipe or
extra-heavy cast-iron pipe or other pipe material approved by the
Borough Engineer must be used.
B. Where the trench is less than four feet deep in a
traveled roadway, extra-heavy cast-iron pipe shall be used and special
bedding, consisting of crushed stone or a concrete cradle, as directed
by the Borough Engineer, shall be used.
C. Service laterals and building sewers for all service
stations, garages, or other establishments storing, using, or dispensing
gasoline, kerosene, benzene or other solvents shall be constructed
of extra-heavy cast-iron pipe with leaded joints.
D. Where lines are laid in fill, extra-heavy cast-iron
soil pipe with lead joints shall be used. The line shall be laid on
a bedding of quarry blend crushed stone or concrete, the bedding to
extend down to unbroken ground.
The slope or grade of a building sewer shall
be no less than 1/8 inch per foot of length and shall be no more than
1/4 inch per foot and downward in the direction of flow. The grade
shall be continuous except that a vertical riser with a cleanout at
ground surface shall be installed when necessary. Where such a vertical
riser is impossible, the maximum grade may be increased to that necessary
to maintain a continuous grade from building drain to sewer lateral.
No building sewer shall be covered until it
has been inspected, tested as provided herein and approved. If any
part of a building sewer is covered before being so inspected, tested
and approved, it shall be uncovered for inspection and testing at
the cost and expense of the owner of the improved property.
When found necessary by the Borough Engineer,
Plumbing Subcode Official or the authorized agent, the building sewer
shall be tested by filling the same with water completely so that
every section shall be tested with not less than a ten-foot head of
water. Water shall be kept in the building sewer for a period of 15
minutes before inspection starts and no leakage should be observable
at the time of inspection.
Where it is found impractical to conduct a water
test on the sewer lines, the following maximum leakage shall be permitted:
100 gpd per inch of pipe diameter per mile of pipe except that for
building sewers and service laterals, no leakage shall be allowed.
Upon inspection and approval of a building sewer
by the Borough Engineer, Plumbing Subcode Official or the authorized
agent, a certificate of approval shall be issued to the owner of the
improved property to be connected to a sewer.
Whenever the Borough Engineer, Plumbing Subcode
Official or the authorized agent has reason to believe any building
sewer has become defective, such building sewer shall be subject to
test and inspection. Defects found upon such test and inspection,
if any, shall be corrected as required by the Borough Engineer or
authorized agent in writing, at the sole cost and expense of the owner
of the improved property served through such building sewer.
Every building sewer of any improved property
shall be maintained in a sanitary and safe operating condition by
the owner of the improved property.
Every excavation for a building sewer shall
be guarded adequately with barricades and lights to protect all persons
and property from injury and damage. Streets, sidewalks and other
public property to be disturbed in the course of building sewer installation
shall be opened and restored at the cost and expense of the owner
of the improved property and pursuant to the applicable provisions
of Borough ordinances.
Connections with sewers where the same are installed
through private property shall in all respects be governed by the
provisions of this chapter.
The Borough shall not be liable for any damage
or expense resulting from leaks, stoppages or defective plumbing or
from any other cause occurring to any premises or within any house
or building. The Borough shall not be liable for a deficiency or failure
of service when occasioned by an emergency, required repairs or failure
from any cause beyond its control. The Borough reserves the right
to restrict the use of sewer service whenever the public welfare may
require. The Borough shall not be liable for any damage or expense
resulting from leaks, stoppages or defective plumbing or from any
other cause occurring to any premises or within any building, and
the owners of improved property, upon connection to the sewer system,
assume all liability and waive any claim against the Borough on account
of the breakage or stoppage of, or any damage or expense to, any service
lateral or building sewer where the cause thereof is found to be in
such service lateral or building sewer.
