No person shall discharge or cause to be discharged any stormwater,
cooling water, or unpolluted industrial waters to any sanitary sewer.
Roof leaders and drains, cellar drains, area drains, foundation drains,
sump pumps, and swimming pool drains shall not be connected to any
sanitary sewer.
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.
Building laterals laid parallel to a bearing wall shall not
be installed closer than three feet to such wall. The building lateral
shall enter the basement through the basement wall no less than 12
inches above the basement floor. In no event shall any building lateral
be placed below the basement floor, except with the express written
approval of the Superintendent. 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.
In building laterals, said cleanouts shall be provided such that the
maximum distance between cleanouts is 100 feet. 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 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 14 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 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 §
132-34; 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. Shortly thereafter the applicant
shall perform permanent restoration of pavement, base, subbase, and
shoulders and/or curbs in accordance with the standards of the road
owner, pursuant to permits obtained by the applicant from the road
owner.
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 Town. 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 laterals, and connections
and appurtenances.
