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 must all conform to the
requirements of the state and town building and plumbing code or other
applicable rules and regulations of the Town. 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 apply.
All costs and expense incident to the installation and connection
of a building sewer are to be borne by the owner.
A separate and independent building sewer must 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 Superintendent,
to meet all requirements of this chapter.
Whenever possible, the building sewer is to 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 must
be lifted by an approved means and discharged to the building sewer.
All excavations for building sewer installation are to 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 must be restored in a manner satisfactory
to the Town.
The applicant for the building sewer permit must notify the
Superintendent when the building sewer is ready for inspection and
connection to the public sewer. The connection is only to be made
under the supervision of the Superintendent.
No person may 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 without the consent of the
Superintendent.
