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 Town Board, shall accompany the application.
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 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 with 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 that 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 five-percent deflection shall be 46 psi when
tested in accordance with ASTM Specification D-2412.
B. 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.
At the point of connection of a street lateral to a main sewer, a standard
wye fitting and sufficient one-eighth-bend (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. The inside diameter of the fittings
shall be the same diameter as the street lateral inside diameter. The wye
branch shall be in the ten-o'clock or two-o'clock position.
The street lateral, including the wye and 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 made after construction
of the main sewer 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-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, and the above-grade
portion shall be painted green and marked "sewer." 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. No sanitary sewer shall
be accepted by the Town 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, 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 and the lateral connection
made thereto as directed by the Superintendent.
Whenever possible, the building lateral shall be brought to the building
at an elevation 10 inches above the basement floor. Building laterals laid
parallel to a bearing wall shall not be installed closer than three feet to
such wall. 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 in no case
shall such depth be less than 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.
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 a 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 §
114-34.
A. The connection of the building lateral to an existing street lateral shall be made at the property line. Except as provided under §
114-25, if a street lateral has not previously been provided, the street lateral will be constructed from the existing public sewer to the property line by a qualified plumber, 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 imbedded 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 Town 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 Town. Any subsequent repairs to the
new street laterals shall be made by the Town at the Town'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
Town 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 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 Town. Any repairs to new street laterals shall be made by the Town
at the Town's expense.
The street lateral, building lateral or the combined lateral shall be
tested for infiltration/exfiltration by an approved method.
A. 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.
B. 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 Town Highway Department shall complete road and shoulder restoration to the Town standards. The cost for such final road and shoulder restoration by the Town Highway Department shall be included with the fees paid with the application for the permit required in §
114-28.
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 Town. The property owner shall indemnify the Town 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.
