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 Town. The Town will provide to a prospective new user a list
of approved contractors authorized to work on the sewer district system.
No person shall discharge or cause to be discharged
any stormwater, cooling water or unpolluted industrial waters 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 Town. The permit application shall be supplemented by any plans,
specifications, or other information considered pertinent, in the
discretion of the Town. A fee for residential, commercial, institutional
and industrial users, as established by the Town Board, shall accompany
the application.
C. Connections to existing manholes shall be made as
directed by the System Operator or the Town Engineer.
A. A separate and independent building lateral shall
be provided for every building, except where one building 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,
courtyard, or driveway, the building sewer from the front building
may be extended to the rear building and the whole considered as one
building sewer.
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 Town Engineer 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 Town Engineer. 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 Town Engineer 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 §§
138-35,
138-36 and
138-92 and the lateral connection made and tested as directed by the Town Engineer. 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
Town Engineer, to meet all requirements of this chapter.
A. Building and street lateral pipe materials shall be
one of the following:
(1) Polyvinyl chloride (PVC) pipe and fittings conforming
to ASTM Specification D-3034-73, SDR-35 Polyvinyl Chloride (PVC) Sewer
Pipe and Fittings. All pipes 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.
(2) Any part of the building or street lateral that is
located within 10 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
Town where the building or street laterals encounter conflicts with
water utility (main line or service connections) or are likely to
be damaged by tree roots.
(3) 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 Town Engineer. 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 Town Engineer.
B. The size and slope of building and street laterals
shall be subject to approval by the Town Engineer, but in no event
shall the internal pipe diameter of gravity laterals be less than
four inches, nor shall the pipe slope be less than 1/4 inch per foot.
C. The street lateral for pressure sewers shall include
a full port curb stop with flow-through diameter equal to that of
the lateral. A curb box shall be installed.
A. At the point of connection of a street lateral to
a main sewer, a standard wye fitting and sufficient one-eighth (45º)
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 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 Town Engineer. All sewer
connections shall be via a properly installed tee 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 Town. A refundable
deposit shall be placed with Town to assure receipt of these amounts.
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 or such other amount as may be set forth in the
Town's fee schedule. No sanitary sewer shall be accepted by the Town
until four copies of this record drawing have been so filed with the
System Operator and the System Operator 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 System Operator in consultation with the Town Engineer, 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 System Operator or the Town Engineer 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 System Operator or the Town Engineer. If required, a new manhole shall be installed in the public sewer pursuant to §§
138-36 and
138-92 and the lateral connection made thereto as directed by the System Operator or the Town Engineer.
A. 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 System Operator in consultation with the Town
Engineer.
B. 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 90º 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 or 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 System Operator and the
Town Engineer. The installation, operation and maintenance of any
pumping operations shall be the responsibility of the building owner.
The type, make and model of the pumping station shall be approved
by the Town Engineer.
All excavations required for the installation
of a building or street lateral shall be open trench work unless otherwise
approved by the Town Engineer. 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 not 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 Town Engineer.
A. Watertight joints. All joints and connections shall
be made watertight.
B. PVC push joints. 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 §
138-50. When the sewer is buried, in no case shall solvent cement pipe joints be acceptable.
A. The connection of the building lateral to an existing street lateral shall be made at the property line. Except as provided under §§
138-29 through
138-31, 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 contractor, 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 Town from any
loss or damage that may directly or indirectly be caused 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 System Operator in consultation
with the Town Engineer.
F. Prior to backfilling, the contractor shall determine
the depth and elevation of the invert of the end of the pipe and also
the location thereof by means of suitable "tie" measurements to the
existing building, etc., which are permanent in nature. This information
and other pertinent data will be recorded on a suitable form and transmitted
to the Town.
If, in the judgment of the System Operator or
the Town Engineer, 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 System Operator, 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 qualified
contractor. The cost of constructing the replacement street lateral
and cleanout shall be at the property owner's expense. 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:
A. Any full pipe method described in §
138-37; or
B. By a suitable joint method, with the prior written
approval of the System Operator and the Town Engineer.
A. Connection inspections.
(1) The applicant for the building lateral permit shall
notify the System Operator 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 Town Engineer.
(2) The applicant for the street lateral permit shall
notify the System Operator 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 System Operator in consultation
with the Town Engineer.
B. Trench inspections. When trenches are excavated for
the laying of building lateral pipes or for the laying of street lateral
pipes, such trenches shall be inspected by the System Operator or
the Town Engineer. Before the trenches are backfilled, the person
performing such work shall notify the System Operator when the laying
of the building lateral is completed, and no backfilling of trenches
shall begin until inspection is completed and approval is obtained
from the Town.
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 Town. When installation requires
disturbance of paved public roads and shoulders, restoration shall
involve backfilling to concrete subgrade. Shortly thereafter, the
contractor shall complete road and shoulder restoration to Town standards.
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.
All buildings receiving new lateral connections
shall be equipped with a metering system acceptable to the Town and
suitable for billing purposes.
All costs associated with the provisions of this article shall be borne by the property owner. The property owner shall indemnify the Town from any loss or damage that may be directly or indirectly caused by the installation of the building and street laterals and connections and appurtenances. The form and substance of any indemnity agreement must be approved by the Attorney for the Town. Other fees and impact charges may be assessed as per Article
XII.
