No person shall uncover, make any connections
with or opening into, use, alter or disturb any public sewer or appurtenance
thereof without first obtaining a written permit from the Village
Board or the Superintendent.
There shall be two classes of building sewer
permits: for residential and commercial service, and for service to
establishments producing industrial wastes. In either case, the owner
or his agent shall make application on a special form furnished by
the Village. The permit application shall be supplemented by any plans,
specifications or other information considered pertinent in the judgment
of the Engineer. A permit and inspection fee shall be paid to the
Village Clerk at the time an application is filed, such fees being
established by resolution of the Village Board.
A separate and independent building sewer shall
be provided for every building. Where building sewers are to serve
multiple-dwelling structures, there shall be provided at least one
separate building sewer for each group of eight apartments (or less).
Existing building sewers may be used in connection
with new buildings only when they are found, on examination and test
by the Village, to meet all requirements of this chapter.
Building and street lateral pipe materials shall
be one of the following:
A. Tar-coated, service grade, cast iron soil pipe conforming
to ASTM Specification A-74, Cast Iron Soil Pipe and Fittings. All
dimensions, weights, and markings of the pipe shall conform to the
requirements of ANSI, Designation A112.5.1, except spigot ends shall
be "plain end" if gasket joints are used.
B. Polyvinyl chloride (PVC) pipe and fittings conforming
to ASTM Specifications D3034-85b, Type PSM Polyvinyl Chloride (PVC)
Sewer Pipe and Fittings or ASTM F789-85, Type PS-46 Poly (Vinyl Chloride)
(PVC) Plastic Gravity Flow Sewer Pipe and Fittings. All pipe shall
be suitable for gravity sewer service. Provisions shall be made for
contraction and expansion at each joint with a rubber ring. The bell
shall consist of an integral wall section stiffened with two PVC retainer
rings which securely lock the solid cross-section ring into position.
Minimum Pipe Stiffness (F/(∆)y) at 5% deflection shall be 46
psi when tested in accordance with ASTM Specification D2412.
C. Any part of the building or street lateral that is
located within five feet of a water main or water service shall be
constructed of cast iron soil pipe encased in concrete, and may be
required by the Village where the building or street lateral is likely
to be damaged by tree roots. If installed on fill or unstable ground,
the building or street lateral shall be of cast iron soil pipe, although
other pipe material may be permitted if such pipe is uniformly supported
on a poured concrete cradle approved by the Village. The distance
between consecutive joints, as measured along the centerline of the
installed pipe, shall not exceed 10 feet, except under abnormal circumstances,
in which case this dimension may be exceeded if approved by the Village.
The size and slope of building or street laterals shall be subject
to approval by the Village, but in no event shall the internal diameter
be less than four inches, nor shall the slope of the pipe be less
than one-fourth-inch per foot.
At the point of connection of a street lateral
to a main sewer, a standard wye fitting and sufficient one-eighth
(45°) bend fittings shall be used. The wye fittings shall be installed
so that flow in the "arm" shall transition smoothly into the flow
in the public sewer. No lateral connection shall be made to the public
sewer which permits the flow into the public sewer from the lateral
to enter at right angles.
The size and slope of the building sewer shall
be subject to the approval of the Village, but in no event shall the
diameter be less than four inches, nor shall the slope of the pipe
be less than one-fourth-inch per foot.
Whenever possible, the building sewer shall
be brought to the building at an elevation below the basement floor.
No building sewer shall be laid parallel to and within three feet
of any bearing wall, which might thereby be weakened. The depth shall
be sufficient to afford protection from frost, but in no event shall
be less than four feet. The building sewer shall be laid at uniform
grade and in straight alignment insofar as possible. Changes in direction
shall be made only with properly curved pipe and fittings. The ends
of the building sewers which are not connected to the building drain
of the structure for any reason shall be sealed against infiltration
by a suitable stopper, plug or other approved means.
In all building in which any building drain is too low to permit gravity flow to the public sewer, sewage carried by such drain shall be lifted by approved mechanical means and discharged to the building sewer, except where a permit has been granted to the contrary under the provisions of Article
II.
All excavations required for the installation
of a building sewer shall be open trenchwork unless otherwise approved
by the Village. Pipe laying and backfill shall be performed in accordance
with Sections 3 through 6 of ASTM Specification C12, except that no
backfill shall be placed until the work has been inspected, and except
that trench widths measured at the top of the installed pipe shall
not exceed 24 inches.
[Amended 2-19-1997 by L.L. No. 2-1997]
A. The connection of the building sewer into an existing public sewer shall be made at the main sewer line. Except as provided under §§
163-30 and
163-31. A clean-out to grade located at the public street right-of-way shall be included in said installation. The owner shall indemnify the Village from any loss or damage that may directly or indirectly be occasioned by the installation of this portion of the building sewer.
B. All subsequent costs and expense for the installation,
maintenance or replacement of the remaining portion of the building
sewer from the main sewer to the residence or place of business shall
be borne by the property owner, including the cost of connecting the
building sewer to the public sewer at the public street main sewer.
C. If, in the judgment of the Village, it is determined
that a building sewer without a public street right-of-way clean-out
needs repair or replacement, the Village can install, at owner's expense,
a clean-out at the public street right-of-way such that the portion
of the building sewer located in the public street or right-of-way
can be maintained independent of the remaining portion of the building
sewer.
D. Any existing portion of the building sewer located
in the public street or right-of-way which upon examination by the
Village is determined to be in need of replacement will be replaced
with a new portion with a public street right-of-way clean-out. The
replacement portion shall be constructed by a licensed plumber. The
cost of constructing the replacement portion and cleanout will be
at the owner's expense.
E. An interior clean-out fitting shall be provided for
each building sewer at a readily accessible location, preferably just
inside the building's basement wall. The fitting shall contain a 45°
branch with removable plug or test tree and so positioned that sewer
cleaning equipment can be inserted therein to clean the building lateral.
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.
When any building sewer is to serve a school, hospital or similar institutional or public building, or is to serve a complex of industrial or commercial buildings, or which, in the opinion of the Village, will receive sewage or industrial wastes of such volume or character that frequent maintenance of said building sewer is anticipated, then such building sewer shall be connected to the public sewer through a manhole. The Village shall determine if and where this type of connection to the public sewer is required. Connections to existing manholes shall be made as directed by the Village. If required, a new manhole shall be installed in the public sewer pursuant to §
163-32, and the building sewer connection made thereto as directed by the Village.
