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.
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, established by §
139-127, 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 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. Plans and
specifications shall be prepared and submitted for approval pursuant
to this Part 2.
Dry sewers shall be designated 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 A112.5.1, except spigot ends shall be plan 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
5% deflection shall be 46 pounds per square inch 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 one-fourth inch per foot.
At the point of connection of a street lateral
to a main sewer, a standard Y-fitting and sufficient one-eighth (forty-five-degree)
bend fittings shall be used. The Y-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 street lateral, including the Y- and one-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-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. 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 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 §§
139-40 and
139-96 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 below 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. The ends of all building or street laterals,
which are not connected to the interior plumbing or 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 the 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.
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 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 plan 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 plan 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 plan 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.
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 §
139-53.
A. Connection.
(1) The connection of the building lateral to an existing street lateral shall be made at the property line. Except as provided under §§
139-35 and
139-36, 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 embedded in concrete.
(2) 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 connection of the building lateral shall also be borne by the
owner.
(3) The owner shall indemnify 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
the 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.
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 Town may
install a cleanout at the property line, at the owner's expense, such
that the street lateral can be maintained independently of the building
lateral.
[Amended 9-1-1994 by L.L. No. 1-1994]
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. 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 any full pipe method described in §
139-41 or by a suitable joint method, with the prior written approval of the Superintendent.
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 §§
139-35 and
139-36, 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.
When trenches are excavated for the laying of building lateral pipes or for laying of street lateral pipes pursuant to §§
139-35 and
139-36, 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's 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 §
139-47.
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 removal 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 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.
