It shall be unlawful to cause, allow or permit the discharge of sewage
from any premises in the Town into or upon any road, public place, stream,
watercourse, ditch, surface or subsurface, groundwater or stormwater drain.
Whenever possible, the building lateral shall be brought to the building
at an elevation below the basement floor. Building laterals laid parallel
to a bearing wall shall not be installed closer than three feet to such wall.
The building lateral shall be laid at uniform grade and in straight alignment
insofar as possible. Changes in direction shall be made only with properly
curved pipe and fittings. Changes of direction of 90° or greater shall
be made with a cleanout which extends to grade, terminating in a terminal
box set in concrete. The ends of all building or street laterals which are
not connected to the interior plumbing of the building for any reason shall
be sealed against infiltration by a suitable stopper, plug or by other approved
means.
In all buildings in which any building drain is too low to permit gravity
flow to the public sewer, wastewater carried by such drain shall be lifted
by mechanical means and discharged to the building lateral, on approval of
the Superintendent.
All excavations required for the installation of a building or street
lateral shall be open trench work unless otherwise approved by the Superintendent.
Pipe laying and backfill, regardless of pipe material used, shall be performed
in general accordance with Paragraphs 3 through 6 of ASTM Specification C-12,
except that trench width, measured at the top of the installed pipe, shall
not exceed the outside pipe diameter plus 24 inches and except that no backfill
shall be placed until the work has been inspected. The depth of cover over
the pipe shall be sufficient to afford protection from frost, but in no case
shall such depth be less than four feet.
The street lateral, building lateral or the combined lateral shall be
tested for infiltration/exfiltration by:
A. Any full pipe method described in §Â
148-19; or
B. By a suitable joint method, with the prior written approval
of the Superintendent.
All excavations for constructing building laterals shall be adequately
protected 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 Superintendent.
When installation requires disturbance of paved public roads and shoulders,
restoration shall involve backfilling to road grade.
All costs associated with the provisions of this Article shall be borne
by the property owner. The property owner shall indemnify the Town from any
loss or damage that may be directly or indirectly occasioned by the installation
of the building and street laterals and connections and appurtenances.
