The following requirements shall apply to existing
house connection sewers:
A. If the construction of a new house connection sewer
on a lot is to include any portion of any existing house connection
sewer on such lot, such construction shall be included and accepted
only when it meets all the requirements for new house connection sewers
and is of a material acceptable to the Engineer and Building Inspector.
B. When it is found necessary to replace any portion
of an existing house connection sewer system between the street curb
and lot line, all that portion of the house connection sewer between
these limits shall be replaced to meet the requirements for new house
connection sewers.
C. When it is found necessary to replace any portion
of an existing house connection sewer between the curb and public
sewer, all that portion of the house connection sewer between these
limits shall be replaced to meet the requirements for new house connection
sewers.
All house connection sewers shall be laid by
the most direct route feasible, free of pinched joints, changes of
grade or unnecessary bends or fittings.
All excavations shall have sufficient width
to allow proper workmanship and permit adequate inspection and shall
be supported in the proper manner. Sheet piling and other timbers
shall be withdrawn in such a manner as to prevent caving of the walls
of the excavation or disturbance of the sewer pipe.
At any point in a main sewer or trunk line sewer
where it is necessary to provide new sewage service, no vitrified
clay Y- or T-saddle will be permitted. Entrance into the main sewer
or trunk sewer will be constructed by first cutting the entrance to
the main sewer or trunk sewer and then inserting a short piece of
four- or six-inch-diameter cast-iron pipe, with bell on one end, into
the aforedescribed entrance in such a manner so as not to protrude
beyond the inside face of said trunk or main sewer. The connecting
pipe shall be so placed as to project upward at an angle of approximately
forty-five degrees (45º) from the horizontal and, in addition,
shall be so placed as to direct the flow of the house connection sewage
downstream into the main or trunk sewer. The only method by which
a connection shall be made into the top of the main or trunk sewer
is if said connection is constructed in accordance with the standard
plan entitled "Standard Chimney Pipe" and in accordance with the aforementioned
connection method. It is hereby further stipulated that all Y-connections
or saddles shall conform to the standard plan entitled "Standard Saddle
Connection." After the short section of connecting pipe is in place,
an embedment of cement concrete shall be placed under and around the
main line sewer pipe and connecting pipe as required for a standard
chimney pipe in accordance with the standard plan. The inside of the
main or trunk sewer shall be checked to see there is no protruding
cement at the joint between the pipe and saddle.
No person shall connect or cause to be connected
any sewer which has been or may hereafter be constructed in any street,
highway, alley, right-of-way or other public place prior to the dedication
and acceptance of such street, alley or right-of-way with any public
sewer of the town, unless such sewer first mentioned shall have been
laid under the supervision and/or to the satisfaction of the Engineer
and in accordance with all provisions of this chapter.
No person shall connect or cause to be connected
any cesspool or septic tank to any public sewer or to any house connection
sewer leading thereto.
All industrial liquid waste pretreatment plants,
grease interceptors, sand interceptors, sewage treatment plants, sewage
pumping plants or ejectors, septic tanks, cesspools, dry wells, dilution
chambers and neutralization tanks shall be constructed in accordance
with the Plumbing Code unless otherwise provided in this chapter.
