No person shall uncover, make any connections to or opening
into, use, alter or disturb any public sewer or appurtenance thereof
without first obtaining a written permit from the Village Board.
A separate and independent building sewer lateral shall be provided
for every building, except, where one building or existing mobile
home on a permanent foundation 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, court, yard or driveway,
the building sewer from the front building may be extended to the
rear building or mobile home and the whole considered as one building
sewer. Where building sewers are to serve multiple dwelling structures,
there shall be provided at least one separate building sewer lateral
for each group of six living units.
Existing building sewer laterals may be used only when they
are found, on examination and testing by the Superintendent, to meet
all requirements of this chapter.
[Amended 8-7-1984 by L.L.
No. 4-1984]
The building sewer lateral shall be tar-coated extra-heavy cast-iron
soil pipe conforming to ASTM Specification A74 and American Standards
Association (ASA) Specification A-40-1, or asbestos-cement house-connection
pipe conforming to ASTM Specification C-428, Type II, minimum class
2400, or plastic pipe, Schedule 35 or heavier, FDR-35, ASTM Ringtite
PVC, gravity sewer with gasketed joint. Joints shall be tight and
waterproof. Any part of the building sewer lateral that is located
within 10 feet of a water service pipe shall be constructed of cast-iron
soil pipe. Cast-iron pipe may be required by the Superintendent where
the building sewer lateral is exposed to damage by tree roots. If
installed in filled or unstable ground, the building sewer lateral
shall be of cast-iron soil pipe, except that nonmetallic material
may be accepted if laid on a suitable concrete bed or cradle as approved
by the Superintendent. Building sewer lateral pipe shall have a maximum
length of five feet between joints.
The size and slope of the building sewer lateral shall be subject
to the approval of the Superintendent, but in no event shall the diameter
be less than four inches, nor shall the slope of the pipe be less
than 1/8 inch per foot.
No building sewer lateral 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 three feet. The building sewer lateral 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 building sewer laterals which are not connected
to the building drain of the structure for any reason shall be sealed
against infiltration by a suitable watertight stopper, plug or other
approved means.
In all buildings in which any building drain is too low to permit
gravity flow to the public sewer, sewage or industrial wastes carried
by such a drain shall be lifted by approved mechanical means and discharged
to the building sewer lateral.
All excavations required for the installation of a building
sewer lateral shall be open trench work unless otherwise approved
by the Superintendent. Pipelaying 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 width measured at the top of the installed
pipe shall not exceed 24 inches.
The connection of the building sewer lateral into an existing public sewer shall be made at the property line. Except as provided under §§
89-24 and
89-25, if the municipal sewer lateral located in the street or right-of-way has not previously been provided, such will be constructed from the existing public sewer to the property line by the Village Department of Public Works upon submittal of a proper request by the property owner and upon deposit of the appropriate permit fee. All costs and expenses incident to the installation and connection of the length of building sewer lateral from the municipal sewer lateral to the owner's building 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 his installation of the building sewer lateral. The method of connection of the building sewer lateral to the public sewer (at the property line) will be dependent upon the type of pipe material used and in all cases shall be approved by the Superintendent of Public Works.
All excavations for building sewer installations 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 lateral is to serve a school, hospital or similar institution or public building or is to serve a complex of industrial or commercial buildings, or which, in the opinion of the Superintendent, 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 Superintendent 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 Superintendent. If required, a new manhole shall be installed in the public sewer pursuant to §
89-26, and the building sewer lateral connection made thereto as directed by the Superintendent.
