After approval of a section or sections of the main sewer and
house sewer laterals, the Sewer Engineer or Borough Engineer shall
file a complete set of house connection maps with the Board of Health
of the Borough of Ho-Ho-Kus and with the Borough Clerk.
Before any portion of the house drain outside of the house is
connected to the house connection, the owner shall prove to the satisfaction
of the Plumbing Inspector that it is clean and conforms in every respect
to the ordinances of the Board of Health, and before any portion of
the house connection is connected to the house sewer lateral, the
Plumbing Inspector shall be satisfied that the house connection is
in good order and conforms in every respect to the requirements for
construction thereof.
Whenever possible, the house connection shall be brought to
the building at an elevation below the basement floor. In all buildings
in which any house drain is too low to permit gravity flow to the
municipal and/or Authority sewage works, sanitary sewage carried by
such house drain shall be lifted by an approved means and discharged
to the house connection.
A.
When installing the house connection, the trenching 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 through the house sewer lateral
during these operations.
B.
In backfilling, the material for the two feet immediately over the
pipe shall be selected so it contains no stones. 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 suitable 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 are bad, such special precaution must be
taken to secure a watertight job as may be directed by the Plumbing
Inspector.
Where connection is made between the house connection outside
of the building and the house sewer lateral, a long radius bend shall
be appropriately installed at this connection, along with a cleanout
as required by the Plumbing Code.[1] This connection shall be subject to the approval of the
Plumbing Inspector, who shall be given ample notice prior to such
work.
The Plumbing Inspector may apply any appropriate test to the
pipes, and the plumber and contractor, at his own expense, shall furnish
all necessary tools, labor, materials and assistants for such tests
and shall remove or repair any defective materials when so ordered
by the Inspector.
Each contractor or other person performing work on private property
for the purpose of connection from the house sewer lateral to the
house drain shall be governed by the terms of the ordinances of the
Board of Health.
