Existing building laterals may be used in connection with new buildings
only when they are found, on examination by the Wastewater Treatment Operator,
to meet all requirements of this chapter.
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 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 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 by
the Wastewater Treatment Operator.
All excavations required for the installation of a building or street
lateral shall be open trench work unless otherwise approved by the Wastewater
Treatment Operator. Pipelaying 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 12 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.
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 Wastewater Treatment Operator. When installation requires the disturbance of paved public roads and shoulders, restoration shall involve backfilling to road grade. Shortly thereafter the Village of Oxford Department of Public Works (DPW) shall complete road and shoulder restoration to Village of Oxford standards. The cost for such final road and shoulder restoration by the DPW shall be included with the fees paid with the application for the permit required in §
230-30.
An interior cleanout fitting shall be provided for each building lateral
at a readily accessible location, preferably just inside the basement wall.
The fitting shall contain a forty-five-degree branch with removable plug or
test tee and shall be so positioned that sewer cleaning equipment can be inserted
therein to clean the building lateral.
All costs associated with the provisions of this Article shall be borne
by the property owner. The property owner shall indemnify the Village of Oxford
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.
