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.
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 exposed and totally encapsulated in not less than three inches
of concrete or exposed and walled and the building rooms above positively
ventilated outdoors. 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 §§
230-31 and
230-94, 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 Part
2.
Dry sewers shall be designed and installed in
accordance with this Part 2.
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 Part 2.
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 A-112.5.1, 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 or SDR-21 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 pounds per square inch
when tested in accordance with ASTM Specification D-2412.
(3) High-density polyethylene (HDPE) pipe shall be made
from high-density, extra-high-molecular-weight compound equaling a
PE3408 designation and shall conform to ASTM 1248 and ASTM 3350; with
a cell classification of 345434 C.
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 may 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 1/8 (45°)
bend fittings shall be used. The wye fittings shall be installed to
enter main at two o'clock or eight o'clock positions 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
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 as set from time to time by resolution of the Town Board shall
be placed with Town of Seneca Falls to assure receipt of these as-builts.
The deposit shall be placed when application is made. No sanitary
sewer shall be accepted by the Town of Seneca Falls 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 §§
230-32 and
230-94, 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 express
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 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 so that the maximum
distance between cleanouts is 100 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. 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. The 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.
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 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. The lubricant
shall be a bland, flax-based, nontoxic material and shall not chemically
attack the gasket material.
D. 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 §
230-45.
A. The connection of the building lateral to an existing street lateral shall be made at the property line. Except as provided under §§
230-26 and
230-27, 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. All laterals shall run perpendicular from the main to the cleanout with no bends or FERNCO’s without prior approval of the Superintendent. The cleanout shall terminate in a cast-iron cover and be encased 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 of Seneca
Falls 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 of Seneca
Falls. Any subsequent repairs to the new street laterals shall be
made by the Town of Seneca Falls at the Town's expense.
F. Any connection of a sewer lateral to a manhole is
prohibited without prior approval of the Superintendent.
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 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 Town of Seneca Falls. 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:
A. Any full pipe method described in §
230-33; or
B. A suitable joint method, with the prior written approval
of the Superintendent.
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 of Seneca Falls Department of Public Works (DPW) shall complete road and shoulder restoration to Town 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 §
230-41.
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 be 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 Part 2 shall be borne by the property owner unless specifically
stated or agreed to be a cost borne by the Town of Seneca Falls. 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.
