The Sewer Engineer shall file a complete set of connection or
wye plans (including latest revisions) with the Board of Health.
No person shall connect any portion of the building drain outside
of the house to the building connection or any portion of the building
connection to the building sewer lateral unless and until the Plumbing
Inspector shall first have issued a certificate to the effect that
the building connection is in good order and conforms in every respect
to the requirements of the Board of Health for construction thereof.
A.
When installing the building connection, the trenches shall be dug
in a careful manner and properly sheathed where required. The excavated
materials shall be piled in a compact heap, so placed as to cause
the least possible inconvenience to the public. Proper barricades
and lights must be maintained around the trench to guard against accidents.
Extreme care shall be taken to prevent any dirt, stones or other undesirable
material from entering the public sewer system during these operations.
B.
In backfilling, the material for the two feet immediately over the
pipe shall contain no stones or other material that may break or damage
the pipe. All backfill material for the trench shall be placed by
tamping in eight-inch layers so as to avoid any settlement. When the
trench has been filled to the proper height, the surface material
shall be replaced and heavily tamped and rolled.
C.
Where the trench is excavated in rock, the rock must be carefully
excavated to a depth of six inches below the grade line of the sewer
and the trench brought to the proper elevation with gravel or other
material satisfactory to the Plumbing Inspector. The remainder of
the trench must be backfilled with approved material.
D.
Nothing in this section shall be construed as abrogating any of the
existing requirements of the Borough relating to the excavation and
backfilling of trenches, but the requirements herein contained shall
be in addition thereto.
E.
Where subsoil conditions, in the opinion of the Plumbing Inspector,
are such as to require special precautions, such steps shall be taken
as may be directed by the Plumbing Inspector. In quicksand, all pipes
must be laid out on planking two inches thick by at least six inches
wide.
