A separate and independent building sewer shall be provided
for every building, except where one building stands at the rear of
another or on an interior lot and no private sewer is available or
can be constructed to the rear building through an adjoining alley,
courtyard or driveway, the building sewer serving the front building
may be extended to the rear building and the whole considered as one
building sewer. The City assumes no obligation or responsibility for
damage caused by or resulting from any single building sewer which
serves two buildings.
Existing building sewers may be used for connection of new buildings
only when they are found, on examination and test by the City, to
meet the requirements of this chapter.
The size, slope, alignment, construction materials, trench excavation
and backfill methods, pipe placement, jointing and testing methods
used in the construction and installation of a building sewer shall
conform to the building and plumbing code or other applicable requirements
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 shall apply.
Whenever practicable, the building sewer shall be brought to
a building at an elevation below the basement floor. In buildings
in which any building drain is too low to permit gravity flow to the
City's treatment works, wastewater carried by such building drain
shall be lifted by an approved means and discharged to a building
sewer draining to the City sewer.
The connection of a building sewer into a treatment works shall
conform to the requirements of the building and plumbing code or other
applicable requirements of the City, or the procedures set forth in

made gastight and watertight and verified by proper testing. Any deviation
from the prescribed procedures and materials must be approved in writing
by the City before installation.
The applicant for a building sewer or other drainage connection
permit shall notify the City when such sewer or drainage connection
is ready for inspection prior to its connection to the City's treatment
works. Such connection inspections and testing as deemed necessary
by the City Manager shall be made by City employees.
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.
The City Manager shall not issue a permit for any class of connection
to the City's treatment works or treatment facilities unless there
is sufficient capacity, not legally committed to other users, in the
treatment works and treatment facilities to convey and adequately
treat the quantity of wastewater which the requested connection will
add to the treatment works and treatment facility. The City Manager
may permit such a connection if there are legally binding commitments
to provide the needed capacity.
It shall be the responsibility of the developer of any mobile
home park in the City to install sanitary sewer lines in said park
in conformance with pertinent sections of this chapter. Furthermore,
one master meter shall be installed, at the owner's expense, that
