[CC 1984 §24.590; Ord. No. 1033 §§1 — 2, 4-9-2012]
A.
A separate
and independent building sewer shall be provided for every building,
except where one (1) building stands at the rear of another on an
interior lot and no private sewer is available or can be constructed
to the rear building through an adjoining alley, courtyard or driveway,
the building sewer from the front building may be extended to the
rear building and the whole considered as one (1) building sewer.
B.
Old
building sewers may be used in connection with new buildings only
when they are found, on examination and test by the Public Works Director,
to meet all requirements of this Article.
C.
The
sewer service line extending from the building to the City main must
be properly sized, sloped to a minimum grade of one-eighth (⅛)
inch per foot of fall to the City main. SDR 35 or SDR 21 (Schedule
40) pipe may be used, except SDR 21 shall be required for any service
line laid underneath a street or roadway. All pipe joints must be
primed and thoroughly glued. The pipe must be laid on a minimum of
four (4) inches of bedding rock (one (1) inch base rock).
All street excavations must be backfilled with no smaller than
one and one-half (1½) inch base rock and thoroughly compacted
in twelve (12) inch layers.
The sewer service line must be laid with a No. 12 copper locator
wire and secured to the pipe a minimum of ten (10) feet apart the
entire length of pipe and exit at clean-out one (1) foot to daylight.
D.
Whenever
possible, the building sewer shall be brought to the building at an
elevation below the basement floor. In all buildings in which any
building drain is too low to permit gravity flow to the public sewer,
sanitary sewage carried by such building drain shall be lifted by
an approved means and discharged to the building sewer.
E.
No
person shall make connection of roof downspouts, interior and exterior
foundation drains, areaway drains or other sources of surface runoff
or ground water to a building sewer or building drain which in turn
is connected directly or indirectly to a public sanitary sewer.
F.
The
connection of the building sewer into the public sewer shall conform
to the requirements of the Building and Plumbing Codes or other applicable
rules and regulations of the City or the procedures set forth in appropriate
specifications of the A.S.T.M. and S.P.C.F. Manual of Practice No.
9. All such connections shall be made gastight and watertight. Any
deviation from the prescribed procedures and materials must be approved
by the Public Works Director before installation.
G.
The
applicant for the building sewer permit shall notify the Public Works
Director when the building sewer is ready for inspection and connection
to the public sewer. The connection shall be made under the supervision
of the Public Works Director or his/her representative. The sewer
service line placed in the excavated trench must be fully exposed
for the final inspection by the City Public Works Department.
H.
All
excavations for building sewer installation shall be adequately guarded
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 City.
