Existing building laterals may be used in connection with new
buildings only when they are found, on examination by the Superintendent,
to meet all requirements of this chapter.
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 backfilling, 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 14inches 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 not in any case shall such depth be less than four feet. Where
it is physically impossible to provide cover of four feet, the depth
may be reduced to a minimum of two feet and the pipe shall be insulated,
as approved by the Superintendent.
The street lateral, building lateral, or the combined lateral
shall be tested for infiltration/exfiltration by:
A. Any full pipe method described in §
382-32, 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 manner satisfactory to the Superintendent. When installation requires disturbance of paved public roads and shoulders, restoration shall involve backfilling to road grade. Shortly thereafter, the Town Department of Public Works (DPW) shall complete road and shoulder restoration to the District's 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 §
382-37.
All costs associated with the provisions of this article shall
be borne by the property owner unless specifically stated or agreed
to be a cost borne by the District. The property owner shall indemnify
the District and 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.
