No unauthorized person shall uncover, make any
connection with, opening into, use, alter or disturb any public sewer
or appurtenance thereof without first obtaining a written permit from
the City Engineer.
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 city 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 that 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 City Engineer, to meet all requirements of this Part
1 of this chapter.
The size, slope, alignment, materials of construction
of a building sewer, and the methods to be used in excavating, placing
the pipe, jointing, testing and backfilling the trench, shall conform
to the requirements of the State Building Construction Code or other applicable rules and regulations of the city.
In the absence of provisions, or in amplification thereof, the materials
and procedures set forth in appropriate specifications of the 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 groundwater to a building sewer or building drain which
in turn is connected directly or indirectly to a public sanitary sewer.
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 city and in a manner satisfactory to
the City Engineer.
