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 stormwater,
surface water, groundwater, roof runoff, subsurface drainage, 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, established from time to time by resolution
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:
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 sound professional
engineering judgment and subject to the approval of the Superintendent.
Where a building lateral is to serve a complex of industrial,
commercial, institutional or dwelling structures, special design of
the building lateral system shall be required. Plans and specifications
shall be prepared and submitted for approval by the Superintendent
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:
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 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 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 gravity building and street laterals shall be
subject to approval by the Superintendent, but in no event shall the
internal pipe diameter for gravity laterals be less than four inches,
nor shall the pipe slope be less than the following:
|
Pipe Size
(inches)
|
Pipe Slope
| |
|---|---|---|
|
4
|
1/4 vertical inch per linear foot (2%)
| |
|
6
|
1/8 vertical inch per linear foot (1%)
| |
|
8
|
0.4%
|
C.
Low-pressure (grinder pump) laterals shall be sized according to
the manufacturers recommendations, typically 1.25 inches in diameter.
A.
At the point of connection of a gravity street lateral to a gravity
main sewer, a standard wye fitting and sufficient 1/8 (45°) 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.
Joining of HDPE laterals to HDPE force main shall be by electrofusion
branch saddle, saddle fusion joint, or by means of an approved premanufactured
fitting. The fitting shall be manufactured for the purpose of connection
of two HDPE pipes without reducing the diameter below the smaller
pipe diameter. The fitting shall be rated for the same pressure as
the pipe and shall be made of HDPE (PE 4710).
The street lateral, including the wye and 1/8 (45°) 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 and 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
applicable district to assure receipt of these as-builts. The deposit
shall be placed when application is made; the amount of the deposit
shall be $1,000 per sheet of plans showing locations of lateral connections.
No sanitary sewer shall be accepted by the applicable district 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 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 § 206-50, and the lateral connection made thereto as directed by the Superintendent.
Whenever possible, the building lateral shall be at least 12
inches above basement floor, except upon approval of 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 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 45° or greater shall be
made with a cleanout which extends to grade, terminating in a terminal
box set in concrete. 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.
See § 206-51 for requirements regarding grinder pump installation.
A.
General.
(1)
The grinder pump shall not be activated until approved by the Superintendent
and the approved electrical underwriter. The property owner shall
provide access to the Superintendent or Superintendent's designated
representative for inspection of the completed pump and service lateral
installation prior to burial.
(2)
Connection to the sewer main will be completed by the applicable
district. The district will install a low-pressure street lateral
and lateral kit (shutoff valve and check valve) to the property line
unless otherwise specified in the map, plan and report for the respective
district.
(3)
Commercial, institutional and multifamily residential buildings with
flows greater than a typical one- or two-family home must have calculations
prepared and submitted to the Superintendent defining the sewage flow
rate and demonstrating appropriate sizing of the grinder pump station
and low-pressure service lateral. Such calculations shall be made
by a professional engineer licensed to practice in the State of New
York and shall bear the seal and signature of the licensed engineer.
B.
Ownership and maintenance. Depending on the district and the provisions
of the respective map, plan and report, privately installed grinder
pumps and service laterals may be required to be transferred to the
Town for ownership, maintenance, and operation upon Town acceptance
of the installation. Should this not be stated in the map, plan and
report for a given district, the property owner shall be responsible
for ownership, maintenance, and operation of the privately installed
grinder pump connection, including, but not limited to, the grinder
pump, alarm panel, service lateral, and building lateral.
A.
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 backfill, 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 40 inches.
B.
All pressurized laterals shall be installed at a minimum depth of
four feet six inches below finished grade.
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 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 § 206-47.
A.
Except as provided in § 206-30, the connection of the building lateral to an existing street lateral shall be made at the property line. 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 clean-out to grade located at the property line. The clean-out 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 owner's expense; all
subsequent costs and expense incidental to the installation and construction
and connection of the building lateral shall also be borne by the
owner.
C.
The owner shall indemnify the applicable district 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 the installation
of the street lateral has been approved by the Superintendent, the
new street lateral shall become the property of the Town of Sullivan.
Any subsequent repairs to the new street laterals shall be made by
the Town of Sullivan.
If, in the judgment of the Superintendent, it is determined
that a building lateral, without a property line clean-out, needs
repair or replacement, the applicable district may install a clean-out
at the property line, at the owner's expense, such that the street
lateral can be maintained independently of the building lateral.
Absent any existing Town laws to the contrary, 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 clean-out. The replacement street lateral shall
be constructed by a plumber. The cost of constructing the replacement
street lateral and clean-out shall be at the owner's expense.
Once the replacement street lateral and clean-out have been constructed
and approved by the Superintendent, the new street lateral shall become
the property of the Town of Sullivan. Any subsequent repairs to the
new street laterals shall be made by the Town of Sullivan.
The street lateral, building lateral or the combined lateral
shall be tested for infiltration/exfiltration by:
The applicant for the building lateral permit shall notify the
Superintendent when the building lateral is ready for inspection and
connection to the street lateral is to be made. The connection shall
be made under the supervision of the Superintendent. When street laterals
are installed pursuant to this article, the property owner, builder
or developer shall notify the Superintendent when the street lateral
is ready for inspection and connection to the main sewer, and such
connection shall be made under the supervision of the Superintendent.
Notice shall be given at least 24 hours in advance of any work requiring
inspection. A connection fee shall be established, from time to time,
by resolution of the Town Board.
When trenches are excavated for the laying of building lateral
pipes or for laying of street lateral pipes pursuant to this article,
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. If a trench is backfilled prior to inspection,
the cost of reopening the trench for inspection shall be the sole
of the property owner.
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. The cost for such final road and shoulder restoration by the Highway Department shall be included with the fees paid with the application for the permit required in § 206-19.
An interior clean-out 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 of Sullivan. The property owner shall
indemnify the Town of Sullivan 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.
