No unauthorized person shall uncover, make any connections with
or opening into, use, alter or disturb any public sewer or appurtenance
thereof without first obtaining a written permit from the Superintendent.
There shall be two classes of building sewer permits: for residential
and commercial service, and for service to establishments producing
industrial wastes. In either case, the owner or his agent shall make
application on a special form furnished by the Borough of Springdale.
The permit application shall be supplemented by any plans, specifications
or other information considered pertinent in the judgment of the Superintendent.
A permit and inspection fee of $5 for a residential or commercial
building sewer permit and $15 for an industrial building sewer permit
shall be paid to the Borough Treasurer at the time the application
is filed.
All costs and expense incident to the installation and connection
of the building sewer shall be borne by the owner. The owner shall
indemnify the Borough of Springdale from any loss or damage that may
directly or indirectly be occasioned by the installation of the building
sewer.
A separate and independent building sewer shall be provided
for every building, except, where one building stands at the rear
of another on an interior lot and no private sewer is available or
can be constructed to the rear building through an adjoining alley,
court, yard or driveway, the building sewer from the front building
may be extended to the rear building and the whole considered as one
building sewer.
Old building sewers may be used in connection with new buildings
only when they are found, on examination and test by the Superintendent,
to meet all requirements of this Part 1.
The building sewer shall be cast iron soil pipe, ASTM specification
(A74-42) or equal; vitrified clay sewer pipe, ASTM specification (C13-44T)
or equal; or other suitable material approved by the Superintendent.
Joints shall be tight and waterproof. Any part of the building sewer
that is located within 10 feet of a water service pipe shall be constructed
of cast iron soil pipe with leaded joints if, in the opinion of the
Superintendent, this is necessary. Cast iron pipe with leaded joints
may be required by the Superintendent where the building sewer is
exposed to damage by tree roots. If installed in field or unstable
ground, the building sewer shall be of cast iron soil pipe, except
that nonmetallic material may be accepted if laid on a suitable concrete
bed or cradle as approved by the Superintendent.
The size and slope of the building sewer shall be subject to
the approval of the Superintendent, but in no event shall the diameter
be less than six inches. The slope of such six-inch pipe shall be
not less than 1/8 inch per foot.
Whenever possible, the building sewer shall be brought to the
building at an elevation below the basement floor. No building sewer
shall be laid parallel to or within three feet of any bearing wall
which might thereby be weakened. The depth shall be sufficient to
afford protection from frost. The building sewer shall be laid at
uniform grade and in straight alignment insofar as possible. Changes
in direction shall be made only with properly curved pipe and fittings.
In all buildings in which any building drain is too low to permit
gravity flow to the public sewer, sanitary sewage carried by such
drain shall be lifted by approved artificial means and discharged
to the building sewer.
All excavations required for the installation of a building
sewer shall be open trenchwork unless otherwise approved by the Superintendent.
Pipe laying and backfill shall be performed in accordance with ASTM
specification (C12-19), except that no backfill shall be placed until
the work has been inspected.
A. All joints and connections shall be made gastight and watertight.
B. Cast iron pipe joints shall be firmly packed with oakum or hemp and
filled with molten lead, federal specification (QQ-L-156), not less
than one inch deep. Lead shall be run in one pouring and caulked tight.
No paint, varnish or other coating shall be permitted on the jointing
material until after the joint has been tested and approved.
C. All joints in vitrified clay pipe or between such pipe and metals
shall be made with approved hot-poured jointing material or cement
mortar, as specified below.
D. Material for hot-poured joints shall not soften sufficiently to destroy
the effectiveness of the joint when subjected to a temperature of
160° F., nor be soluble in any of the wastes carried by the drainage
system. The joint shall first be caulked tight with jute, hemp or
similar approved material.
E. Cement joints shall be made by packing a closely twisted jute or
oakum gasket of suitable size to fill partly the annular space between
the pipes. The remaining space shall be filled and firmly compacted
with mortar composed of one part portland cement and three parts mortar
sand. The material shall be mixed dry; only sufficient water shall
be added to make the mixture workable. Mortar which has begun to set
shall not be used or retempered. Lime putty or dehydrated lime may
be substituted to the extent of not more than 25% of the volume of
the portland cement that may be added.
F. Other jointing materials and methods may be used only by approval
of the Superintendent.
The connection of the building sewer into the public sewer shall
be made at the Y-branch if such branch is available at a suitable
location. If the public sewer is 12 inches in diameter or less and
no properly located Y-branch is available, the owner shall, at his
expense, install a Y-branch in the public sewer at the location specified
by the Superintendent. Where the public sewer is greater than 12 inches
in diameter and no properly located Y-branch is available, a neat
hole may be cut into the public sewer to receive the building sewer,
with entry in the downstream direction at an angle of about 45°.
A forty-five-degree ell may be used to make such connection, with
the spigot end cut so as not to extend past the inner surface of the
public sewer. The invert of the building sewer at the point of connection
shall be at the same or at a higher elevation than the invert of the
public sewer. A smooth, neat joint shall be made, and the connection
made secure and watertight by encasement in concrete. Special fittings
may be used for the connection only when approved by the Superintendent.
The applicant for the building sewer permit shall notify the
Superintendent when the building sewer is ready for inspection and
connection to the public sewer. The connection shall be made under
the supervision of the Superintendent or his representative.
All excavations for building sewer installation shall be adequately
guarded with barricades and lights so as to protect the public from
hazard. Streets, sidewalks, parkways and other public property disturbed
in the course of the work shall be restored in a manner satisfactory
to the Borough of Springdale.
