No unauthorized person shall uncover, make any
connection with or opening into, use, alter, or disturb any public
sewer or appurtenance thereof without first obtaining a written permit
from the Superintendent.
All costs and expenses incident to the installation
and connection of the building sewer shall be borne by the owner.
The owner shall indemnify the Village from any loss or damage that
may directly or indirectly be occasioned by the installation of the
building sewer.
A separate and independent building sewer shall
be provided for every building.
Old building sewers may be used in connection
with new buildings only when they are found, on examination and test
by the Superintendent, to meet all requirements of this chapter.
The size, alignment, and materials of construction
of a building sewer and the methods to be used in excavating, placing
of the pipe, jointing, testing and backfilling the trench shall all
conform to the following:
A. Materials. The following piping materials are acceptable
for use as building sewers:
(2) PVC Schedule 40 or sewer pipe standard dimension ratio
21. Stab-type fittings and joints with locked-in rubber sealing rings
meeting ASTM D-1869 or solvent welded joints. Acceptable manufacturers,
Johns-Manville, Certainteed, or equal.
(3) Cast-iron pipe ASA Specification 21 with minimum working
pressure of 150 psi, exterior to be coated with coal tar pitch, interior
varnished. Fittings and joints to be push-on type with rubber seal
rings. Acceptable manufacturers: U.S. Pipe, Pioneer, or equal.
(4) Adapters from one size pipe to another or from one
type of material to another shall be designed for the particular union
for which it will be used and shall be manufactured by Fernco or by
the manufacturer of the pipe being used.
B. Installation.
(1) All building sewers shall originate from a lateral
wherever one is available. When one is not available the Superintendent
will install one and charge the property owner(s) for all required
work at the cost to the Village.
(2) Minimum size building sewer pipe is four inches. All
buildings constituting two through four sewer users shall install
six-inch "minimum" building sewers. All building sewers for more than
four combined equivalent users shall be sized by a licensed engineer.
All building sewers shall be brought to the building below ground
level. When rock interfaces with these installation depths, the pipe
may run above the rock whenever a minimum cover of 24 inches and the
minimum slope is maintained.
(3) Four-inch building sewer pipe shall be installed at
a minimum slope of 1.5% or 3/16 inch per foot.
(4) Six-inch building sewer pipe shall be installed at
a minimum of 1.0% or 1/8 inch per foot.
(5) All building sewer pipe shall be laid on a four-inch
bed of No. 1 crushed stone or gravel, free of stones larger than one
inch. The pipe backfill material to a level 12 inches above the pipe
shall be free of stones larger than two inches.
(6) All connections shall be made gastight and watertight.
Any deviation from the procedures and materials as set forth in this
section must be approved by the Superintendent before installation.
(7) In all buildings in which any building drain is too
low to permit gravity flow to the public sanitary sewer, sanitary
sewage carried by such building drain shall be lifted by an approved
means and discharged to the building sewer.
(8) No person shall make connection of roof downspouts,
exterior foundation drains, areaway drains, or other sources of surface
runoff or groundwater to a building sewer or building drain which
in turn is connected directly or indirectly to a public sanitary sewer.
(9) The applicant for the building sewer permit shall
notify the Superintendent when the building sewer is ready for inspection
and connection to the public sewer. The connection shall be made under
the supervision of the Superintendent or his representative.
(10)
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 Village.
