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.
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 of this
chapter.
The size, slope, alignment, materials of construction
of a building sewer and the methods to be used in excavating, placing
of the pipe, jointing, testing and backfilling the trench shall all
conform to the requirements of the Building and Plumbing Code or other applicable rules and regulations of the Village.
In the absence of code provisions or in amplification thereof, the
materials and procedures set forth in appropriate specifications of
ASTM and WPCF Manual of Practice No. 9 shall apply.
Whenever possible, the building sewer shall
be brought to the building at an elevation below the basement floor.
In all buildings in which any building drain is too low to permit
gravity flow to the public sewer, sanitary sewage carried by such
building drain shall be lifted by an approved means and discharged
to the building sewer.
No person shall make connection of roof downspouts,
exterior foundation drains, areaway drains or other sources of surface
runoff or ground water to a building sewer or building drain which
in turn is connected, directly or indirectly, to a public sanitary
sewer.
The connection of the building sewer into the
public sewer shall conform to the requirements of the Building and
Plumbing Code or other applicable rules and regulations of the Village,
or the procedures set forth in appropriate specifications of the ASTM
and the WPCF Manual of Practice No. 9. All such connections shall
be made gastight and watertight. Any deviation from the prescribed
procedures and materials must be approved by the Superintendent before
installation.
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 Village.
