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.
[Amended 12-19-2007 by L.L. No. 3-2007]
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. Cooling water or industrial water containing contaminants and chlorinated swimming pool water shall not be discharged into the MS4, except as provided in Article
XV of this chapter.
A. There shall be two classes of sewer lateral permits:
(1) For residential, commercial, and institutional service; and
(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 of Elma 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:
(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 air-tight
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 §§
115-34 and
115-109 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.
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 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.
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. At the point of connection of a street lateral to a main sewer, a
standard wye fitting and sufficient one-eighth (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. 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 have a six-inch PVC
riser to the surface, to locate the lateral connection. Upon connection
the six-inch PVC riser will be reinstalled to serve as a cleanout
for the house lateral. The cleanout will be capped watertight at grade
and located on the inspection map using measurements off the house.
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. No sanitary sewer shall be accepted by Town
of Elma 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 §§
115-35 and
115-109, 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 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 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.
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 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 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.
B. Sewer lateral shall be installed in a separate trench with a three-foot minimum distance to any other utility. Refer to §
115-33P through
V on installation procedures.
C. Cast iron pipe shall be used to go through the basement wall and
shall extend a minimum of 10 feet past the building or extensions
of the building (i.e., porches, garage). At this point a J trap shall
be installed with a riser extending 12 inches above final grade. This
pipe will be topped off with a mushroom-style vent cap.
D. Watertight capped cleanouts shall be installed at a maximum distance
of 75 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 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, flaxbase, 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 §
115-55.
A. The connection of the building lateral to an existing street lateral shall be made at the property line. Except as provided under §§
115-29 and
115-30, 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.
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 Elma 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.
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 of Elma 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.
The street lateral, building lateral, or the combined lateral
shall be tested for infiltration/exfiltration by:
A. Pipe method described in §
115-41; or
B. By 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 Elma Department of Public Works (DPW) shall complete road and shoulder restoration to the Town of Elma 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 §
115-49.
A. 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.
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 of Elma. The property owner shall indemnify
the Town of Elma 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.
