A.
Permit required for sewer connections. 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.
B.
Inflow/infiltration prohibited. 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.
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.
C.
Connections to existing manholes shall be made as directed by the
Superintendent.
A.
New building laterals.
(1)
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.
(2)
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:
(3)
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.
B.
Laterals serving several buildings. 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.
C.
Laterals serving complexes. 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 §§ 382-30D and 382-77 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.
D.
Dry sewers. 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 five-percent
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.
C.
The street lateral shall include a full port curb stop with flow-through
diameter equal to that of the lateral. A curb box shall be installed.
A.
Street lateral to public sewer connection.
(1)
At the point of connection of a street lateral to a main sewer, a
standard wye fitting and sufficient one-eighth-bend (45º) 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.
(2)
The inside diameter of the fittings shall be same diameter as the
street lateral inside diameter.
B.
Future connection locations; as-built drawings. 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 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 the District 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 the District
until four copies of this record drawing have been so filed with the
Superintendent and the Superintendent has approved the submitted drawings.
C.
Special manhole requirements. 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 §§ 382-31 and 382-77, and the lateral connection made thereto as directed by the Superintendent.
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 Superintendent.
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, 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 14inches 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 Superintendent.
A.
Watertight joints. All joints and connections shall be made watertight.
B.
Cast-iron pipe poured joints. 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 160º F., nor
be soluble in any of the wastes carried by the lateral.
C.
Cast-iron push joints. 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.
A.
Building lateral/street lateral connection.
(1)
The connection of the building lateral to an existing street lateral shall be made at the property line. Except as provided under § 382-29, 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 licensed 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.
(2)
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.
(3)
The property owner shall indemnity the District and the Town from
any loss or damage that may directly or indirectly be occasioned by
the installation of the building lateral.
(4)
It shall be the responsibility of the property owner to maintain,
repair, or replace the building lateral, as needed.
(5)
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 District. Any
subsequent repairs to the new street laterals shall be made by the
District at the District's expense.
B.
Cleanout repair/replacement. If, in the judgment of the Superintendent,
it is determined that a building lateral, without a property line
cleanout, needs repair or replacement, the District 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.
C.
Street lateral replacement; ownership. 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 District. Any repairs to new street
laterals shall be made by the District at the District's expense.
The street lateral, building lateral, or the combined lateral
shall be tested for infiltration/exfiltration by:
A.
Connection inspection.
(1)
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.
(2)
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.
B.
Trench inspections. 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 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 Department of Public Works (DPW) shall complete road and shoulder restoration to the District's standards. The cost for such final road and shoulder restoration by the DPW shall be included with the fees paid with the application for the permit required in § 382-37.
A.
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.
B.
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 District. The property owner shall indemnify
the District and 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.
