All costs and expenses incidental to the installation and connection
of the building sewer shall be borne by the owner of the property
being connected to the public sewer, and the owner shall be responsible
for and shall reimburse the City for any loss or damage to the public
sewer caused, directly or indirectly, 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 it is not possible to make a direct
connection from such rear building to the public sewer, in which event
the building sewer connecting the front building to the public sewer
may be extended to the rear building and the whole considered as one
building sewer.
An existing building sewer previously used to service a former
building located on a particular property may be used to service a
new building to be constructed on the property only if, upon examination
and testing by the City Engineer, such building sewer is found to
meet all the requirements of this chapter.
The size, slope, alignment, material for construction of a building
sewer, and the method to be used in excavating, placing of pipe, jointing,
testing and backfilling, shall all conform to the requirements of
the uniform construction codes and all other applicable ordinances, rules and regulations
of the City, and all other applicable provisions of law.
Whenever possible, the building sewer shall enter the building
at an elevation below that of the basement floor.
In any building in which the building drain is too low to permit
gravity flow to the public sewer, sewerage carried by such building
drain shall be lifted by an approved means and discharged to the building
sewer, and each such connection shall be protected by a backflow preventive
device which shall be maintained by the owner of the property.
No person shall connect any roof, downspout, foundation drain,
areaway drain or other sources of surface runoff or groundwater to
a building sewer or building drain which is connected directly or
indirectly to a public sewer unless prior approval therefor is granted
by the City Engineer, which approval shall be granted only if necessary
for proper and sanitary disposal of polluted surface drain water.
Any person installing a building sewer shall notify the City
Engineer, in advance, when such building sewer is to be connected
to the public sewer, and such connection and testing thereof shall
be made under the supervision of the City Engineer or his representative.
