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 Director of Municipal Utilities, to meet all requirements of
this article.
The size, slope, alignment, and 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 New York State Uniform
Fire Prevention and Building Code or other applicable rules and regulations
of the City. In the absence of code 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 will 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

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 New York State
Uniform Fire Prevention and Building Code, all ordinances and local
laws or other applicable rules and regulations of the City, 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 Director of Municipal Utilities
before installation.
The applicant for the building sewer permit
shall notify the Director of Municipal Utilities when the building
sewer is ready for inspection and connection to the public sewer.
The connection shall be made under the supervision of the Director
of Municipal Utilities or his or her 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 City.
All existing connections of roof water, surface
runoff or groundwater to sanitary or combined sewers shall be eliminated
within 90 days of written notification to do so from the Director
of Municipal Utilities.
The owner or occupant of any lot or parcel of

shall at all times maintain the sewer lateral extending therefrom
to the trunk sewer in said street, public highway, lane or alley free
from obstruction of any kind.
