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 §
235-130, 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:
(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 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 chapter.
Dry sewers shall be designated 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 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 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.
At the point of connection of a street lateral to a main sewer,
a standard wye fitting and sufficient one-eighth-bend (45°) 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.
A. 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.
B. The location of all lateral connections shall be indicated on a drawing,
and four copies of this drawing, showing the as-build 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 §
235-30 and §
235-99, 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. Pipelaying 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.
All joints and connections shall be made watertight.
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.
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 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 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-based, 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 §
235-48.
A. The connection of the building lateral to an existing street lateral shall be made at the property line. Except as provided under §
235-25 and §
235-26, 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.
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 connection of
the building lateral shall also be borne by the owner.
C. 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.
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. Any subsequent
repairs to the new street laterals shall be made by the Town at the
Town's expense.
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 12-14-1994 by L.L. No. 12-1994]
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 the 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 §
235-31; or
B. By a suitable joint method, with the prior written approval of the
Superintendent.
[Amended 3-28-1996 by L.L. No. 2-1996]
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 §
235-49, 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.
[Amended 3-28-1996 by L.L. No. 2-1996]
When trenches are excavated for the laying of building lateral pipes or for laying of street lateral pipes pursuant to §
235-49, 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 Department of Public Works (DPW) shall complete road and shoulder restoration to the Town'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 §
235-42.
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 45° branch with removal
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 or the Gananda Sewer District. The
property owner shall indemnify the Town and the Gananda Sewer District
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.
