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 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 no 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 §
300-25; 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 and compacting to road grade in six-inch
lifts with Item 4 gravel topped with eight inches of crusher run,
four inches of binder and two inches of top. The cost for such final
road and shoulder restoration shall be at the owner's expense.
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 so positioned that sewer
cleaning equipment can be inserted therein to clean the building lateral.
The cleanout diameter shall be no less than the building lateral diameter.
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 Village. The property owner
shall indemnify the Village 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.
