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.
No person shall discharge or cause to be discharged
any storm cooling water or unpolluted industrial waters to any sanitary
sewer. Swimming pool drains shall not be connected to any sanitary
sewer.
A. There shall be two classes of sewer lateral permits:
(1) For residential, commercial and institutional service.
(2) For service to establishments producing industrial
wastes.
B. In either case, a permit application shall be submitted
to the Superintendent. The permit application shall be supplemented
by any plans, specifications or other information considered pertinent,
in the judgment of the Superintendent. A fee for residential, commercial,
institutional and industrial users, as established by the Village
Board, shall accompany the application.
C. Connections to existing manholes shall be made as
directed by the Superintendent.
A. A separate and independent building lateral shall
be provided for every building requiring sanitary facilities. When,
however, there is a building behind a front building, the second building
may use the front building's building lateral, if there is no other
way to provide sanitary service to the back building.
B. New street laterals and/or building laterals shall
not go under building basements. In like fashion, a building shall
not be constructed over an existing lateral; the lateral shall be
relocated after the Superintendent has approved plans showing the
relocation. If relocation is not physically possible then the lateral
shall be:
(1) Exposed and totally encapsulated in not less than
three inches of concrete; or
(2) Exposed and walled and the building rooms above positively
ventilated outdoors.
C. All existing manholes in or under the basement shall
be sealed airtight in a manner acceptable to the Superintendent. No
new manholes shall be constructed on the portion of the lateral under
the building.
When building laterals are to serve multiple
dwelling structures, the building lateral shall be sized in accordance
with the metered water use and with sound professional engineering
judgment.
Where a lateral sewer is to serve a complex of industrial, commercial, institutional or dwelling structures, special design of the building lateral system shall be required. Such lateral sewer shall be connected to the public sewer through a manhole. The Superintendent shall determine if and where this connection to the public sewer is required. If required, a new manhole shall be installed in the public sewer pursuant to §§
177-34 and
177-109 and the lateral connection made and tested as directed by the Superintendent. Plans and specifications shall be prepared and submitted for approval pursuant to this chapter.
Dry sewers shall be designed and installed in
accordance to this chapter.
Existing building laterals may be used in connection
with new buildings only when they are found, on examination by the
Superintendent, to meet all requirements of this chapter.
A. Building and street lateral pipe materials shall be
one of the following:
(1) Tar-coated, service grade, cast iron soil pipe conforming
to ASTM Specification A-74, Cast Iron Pipe and Fittings. All dimensions,
weight 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.
(2) Polyvinyl chloride (PVC) pipe and fittings conforming
to ASTM Specification D-3034-73, SDR-35 Polyvinyl Chloride (PVC) 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 D-2412.
B. 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. Cast iron soil pipe may be required
by the Superintendent 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 Superintendent. The distance
between consecutive joints, as measured along the center line of the
installed pipe, shall not be less than 10 feet, except under abnormal
circumstances, in which case this dimension may be diminished, if
approved by the Superintendent. The size and slope of building and
street laterals shall be subject to approval by the Superintendent,
but in no event shall the internal pipe diameter be less than four
inches, nor shall the pipe slope be less than 1/4 inch per foot.
A. At the point of connection of a street lateral to
a main sewer, a standard wye fitting and sufficient one-eighth (forty-five-degree)
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.
B. The inside diameter of the fittings shall be same
diameter as the street lateral inside diameter.
The street lateral, including the wye and one-eighth
bend fittings, shall be connected to the main sewer at the time of
constructing the main sewer, for each proposed lot for either immediate
or future development. Laterals installed for future development shall
be fitted with a standard plug approved for use by the Superintendent.
All sewer connections shall be via a properly installed saddle on
the main sewer pipe. No portion of the lateral pipe shall protrude
into the main sewer pipe. The location of all lateral connections
shall be field marked with a two-inch by six-inch corrosion and rot
resistant board. The marker board shall extend from the depth of the
lateral to a minimum of two feet above grade. The location of all
lateral connections shall be indicated on a drawing with a minimum
of three tie lines indicated. Four copies of this drawing, showing
the as-built location of these connections, shall be furnished to
the Superintendent. A refundable deposit shall be placed with Village
to assure receipt of these as-builts. The deposit shall be placed
when application is made; the amount of the deposit shall be $100
per sheet of plans showing locations of lateral connections. No sanitary
sewer shall be accepted by Village until four copies of this record
drawing have been so filed with the Superintendent and the Superintendent
has approved the submitted drawings.
When any street lateral is to serve a school, hospital or similar institution, or public housing, or is to serve a complex of industrial or commercial buildings, or which, in the opinion of the Superintendent, will receive wastewater or industrial wastes of such volume or character that frequent maintenance of said building or street lateral is anticipated, then such street lateral 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 §§
177-35 and
177-109, and the lateral connection made thereto as directed by the Superintendent.
Building laterals laid parallel to a bearing
wall shall not be installed closer than three feet to such wall. The
building lateral shall enter the basement through the basement wall
no less than 12 inches above the basement floor. In no event shall
any building lateral be placed below the basement floor, except with
the expressed written approval of the Superintendent. The building
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. Changes of direction of 90° or greater
shall be made with a cleanout which extends to grade, terminating
in a terminal box set in concrete. In building laterals, said cleanouts
shall be provided such that the maximum distance between cleanouts
is 75 feet. The ends of all building or street laterals which are
not connected to the interior plumbing of the building, for any reason,
shall be sealed against infiltration by a suitable stopper, plug or
by other approved means.
In all buildings in which any building drain
is too low to permit gravity flow to the public sewer, wastewater
carried by such drain shall be lifted by mechanical means and discharged
to the building lateral, on approval of the Superintendent.
All excavations required for the installation
of a building or street lateral shall be open trench work unless otherwise
approved by the Superintendent. Pipe laying and backfilling, regardless
of pipe material used, shall be performed in general accordance with
paragraphs 3 through 6 of ASTM Specification C-12, except that trench
width, measured at the top of the installed pipe, shall not exceed
the outside pipe diameter plus 14 inches and, except that no backfill
shall be placed until the work has been inspected. The depth of cover
over the pipe shall be sufficient to afford protection from frost,
but no in any case shall such depth be less than four feet. Where
it is physically impossible to provide cover of four feet, the depth
may be reduced to a minimum of two feet and the pipe shall be insulated,
as approved by the Superintendent.
All joints and connections shall be made watertight.
Poured joints for cast-iron pipe shall be firmly
packed with oakum or hemp, and the annulus filled with an approved
compound not less than one inch deep. Said compound shall be run in
with a single pouring, and caulked tight, if appropriate for the compound
used. No paint, varnish or other coatings shall be permitted on the
jointing material until after the joint has been tested and approved.
The transition joint between cast-iron pipe, and other pipe materials
shall be made with special adapters and jointing materials approved
by the Superintendent. If such joints are hot-poured, the material
shall not soften sufficiently to destroy the effectiveness of the
joint when subjected to a temperature of 160° F., nor be soluble
in any of the wastes carried by the lateral.
Premolded gaskets may be used for hub and plain
end cast iron pipe joints and joints with fittings, if approved by
the Superintendent. The gasket shall be a neoprene compression-type
unit which provides a positive seal in the assembled joint. The gasket
shall be premolded, one-piece unit, designed for joining the cast-iron
hub and plain end soil pipe and fittings. The assembled joint shall
be sealed by compression of the gasket between the exterior surface
of the spigot and the interior surface of the hub. The joint shall
be assembled following the manufacturer's recommendations using acceptable
lubricant and special pipe-coupling tools designed for that purpose.
The plain spigot end shall be forced into the hub end of the pipe
for the full depth of the hub itself. Lubricant shall be a bland,
flax-base, nontoxic material and shall not chemically attack the gasket
material.
Joints for PVC sewer pipe shall follow the manufacturer's recommendations, using properly designed couplings and rubber gaskets pursuant to the published information relating thereto, and conforming to the applicable ASTM specification identified in §
177-55.
A. The connection of the building lateral to an existing street lateral shall be made at the property line. Except as provided under §§
177-29 and
177-30, if a street lateral has not previously been provided, the street lateral will be constructed from the existing public sewer to the property line, at the owner's expense. The street lateral shall be installed with a properly sealed and covered cleanout to grade located at the property line. The cleanout shall terminate in a metal box embedded in concrete.
B. The cost of constructing the street lateral from the
existing public sewer to the property line shall be at the property
owner's expense; all subsequent costs and expense incidental to the
installation and connection of the building lateral shall also be
borne by the owner.
C. The property owner shall indemnify the Village from
any loss or damage that may directly or indirectly be occasioned by
the installation of the building lateral.
D. It shall be the responsibility of the property owner
to maintain, repair or replace the building lateral, as needed.
E. The method of connection of the building lateral to
the street lateral will be dependent upon the type of sewer pipe material
and, in all cases, shall be approved by the Superintendent. After
installation of the street lateral has been approved by the Superintendent,
the new street lateral shall become the property of the Village. Any
subsequent repairs to the new street laterals shall be made by the
property owner at the property owner's expense.
If, in the judgment of the Superintendent, it
is determined that a building lateral without a property line cleanout
needs repair or replacement, the Village may install a cleanout at
the property line, at the property owner's expense, such that the
street lateral can be maintained independently of the building lateral.
Any existing street lateral which, upon examination
by the Superintendent, is determined to be in need of replacement
will be replaced with a new street lateral with a property line cleanout.
The replacement street lateral shall be constructed by a licensed
plumber. The cost of constructing the replacement street lateral and
cleanout shall be at the property owner's expense. Once the replacement
street lateral and cleanout have been constructed and approved by
the Superintendent, the new street lateral shall become the property
of the Village. Any repairs to new street laterals shall be made by
the property owner at the property owner's expense.
The street lateral, building lateral or the
combined lateral shall be tested for infiltration/exfiltration by:
B. By a suitable joint method, with the prior written
approval of the Superintendent.
The applicant for the building lateral permit
shall notify the Superintendent when the building lateral is ready
for inspection and connection is to be made to the street lateral.
The connection shall be made under the supervision of the Superintendent.
The applicant for the street lateral permit shall notify the Superintendent
when the street lateral is ready for inspection and connection is
to be made to the main sewer. The connection shall be made under the
supervision of the Superintendent.
When trenches are excavated for the laying of
building lateral pipes or for laying of street lateral pipes, such
trenches shall be inspected by the Superintendent. Before the trenches
are backfilled, the person performing such work shall notify the Superintendent
when the laying of the building lateral is completed, and no backfilling
of trenches shall begin until approval is obtained from the Superintendent.
All excavations for constructing building laterals shall be adequately protected 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 Superintendent. When installation requires disturbance of paved public roads and shoulders, restoration shall involve backfilling to road grade. Shortly thereafter, the contractor shall complete road and shoulder restoration to Village standards. A performance bond or guaranty, to be set from time to time by the Village Board, shall be required before said excavation shall begin, and which shall be included with the fees paid with the application for the permit required in §
177-49.
An interior cleanout fitting shall be provided
for each building lateral at a readily accessible location, preferably
just inside the basement wall. The fitting shall contain a forty-five-degree
branch with removable plug or test tee, and so positioned that sewer
cleaning equipment can be inserted therein to clean the building lateral.
The cleanout diameter shall be no less than the building lateral diameter.
All costs associated with the provisions of
this article shall be borne by the property owner unless specifically
stated or agreed to be a cost borne by the Village. The property owner
shall indemnify the Village from any loss or damage that may be directly
or indirectly occasioned by the installation of the building and street
laterals and connections and appurtenances.
