No unauthorized person shall uncover, make any connection with
or opening into, use, alter or disturb any public sewer or appurtenance
without first obtaining a written permit from the Sewer District.
No person shall discharge or cause to be discharged any stormwater,
cooling water or unpolluted industrial waters to any sanitary sewer.
Swimming pool drains shall not be connected to any sanitary sewer.
A permit application shall be submitted to the Sewer District.
The permit application shall be supplemented by any plans, specifications
or other information required by the Sewer District. A fee, established
by the Sewer District, 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. Conversely, a building shall not be constructed over an
existing lateral; the lateral shall be relocated after the Sewer District
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 four inches of concrete.
When building laterals are to serve multiple-dwelling structures,
the building lateral shall be sized in accordance with the metered
water use and shall be reviewed by the engineer for the Town.
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 Sewer District 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 and the lateral
connection made and tested as directed by the Sewer District. Plans
and specifications shall be submitted to the Sewer District for approval.
Dry sewers shall be designed and installed in accordance to
this Part 2.
Existing building laterals may be used in connection with new
buildings only when they are found, on examination by the Sewer Districts,
to meet all requirements of these rules and regulations.
Building and street lateral pipe and fittings materials shall
be one of the following:
A. Polyvinyl chloride (PVC) gravity sewer pipe and fittings conforming
to ASTM Specification D3034-73, SDR-35 polyvinyl chloride (PVC) sewer
pipe and fittings with elastomeric gasket joints. 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.
B. Cast-iron soil pipe (CISP) and fittings for gravity sewer service,
tar-coated, service grade, conforming to ASTM Specification A-74,
with hub and plain ends and premolded neoprene, compression-type,
one-piece gasket joints. All dimensions, weight and markings of the
pipe shall conform to the requirements of ANSI, Designation A112.5.1.
C. Polyvinyl chloride (PVC) pressure-rated pipe and fittings for force
mains, ASTM D2241 SDR21, two-hundred-psi pressure rating with elastomeric
gasket joints and adapters.
D. Sewer pipe saddle, SEALTITE Type E cast-iron saddle with ATSM C-361
rubber tubular ring gasket, and stainless steel strap at least 24
gage by 2 1/2 inches wide and two 3/8-inch stainless steel T-bolts
and nuts; model EH gasketed bell to accept PVC-SDR-1935 pipe or model
EX hub to accept extra heavy CISP, as manufactured by the General
Engineering Company.
At the point of connection of a street lateral to a main sewer,
a standard tee-wye fitting and sufficient 1/8th- (45°) bend fittings
shall be used. The tee-wye fittings shall be installed so that flow
in the lateral shall transition smoothly into the flow in the public
sewer.
The street lateral, including the tee-wye and 1/8th-bend fittings,
shall be connected to the main sewer at the time of constructing the
main sewer and extended to the right-of-way line or easement line
for each proposed lot with the approved building permit.
All future lateral connections to existing main sewers shall
be made using 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-four-inch hardwood marker. The marker board shall
extend from the depth of the lateral to six inches above finished
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 Sewer District
prior to issuing a certificate of occupancy.
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 Sewer District,
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 Sewer District 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 Sewer District. If required,
a new manhole shall be installed in the public sewer and the lateral
connection made as directed by the Sewer District.
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
five 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 deflected joints and fittings. Changes
of direction of 45° or greater shall be made with a cleanout which
extends to grade, terminating with a watertight screw plug. 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 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. Plans and specifications of such systems, including force
mains, shall be submitted for approval to the engineer for the Town.
A. All installation of building or street laterals shall be in open
trench excavations unless otherwise required by the Highway Superintendent.
Pipe laying and backfilling shall be performed in conformance with
Town Design and Construction Standards. No backfill shall be placed
until the work has been inspected by the Sewer District. The depth
of cover over the pipe shall be sufficient to afford protection from
frost and from traffic loads.
B. The size and slope of building and street laterals shall be subject
to approval by the Town Engineer, but in no case shall the internal
pipe diameter of gravity laterals be less than four inches, nor shall
the pipe slope be less than 1/4 inch per foot.
All joints and connections shall be made watertight.
A. The connection of the building lateral to an existing street lateral
shall be made at the property line. If a street lateral has not been
previously provided, the street lateral shall be constructed from
the existing public sewer to the property line at the property owner's
expense. Cleanouts shall be provided for building laterals at the
property line, at all horizontal bends, at maximum spacing of 100
feet and at force-main-to-gravity-sewer connections.
B. All costs and expenses incidental to the installation and connection
of the building lateral shall be borne by the property owner. It shall
be the responsibility of the property owner to maintain, repair or
replace the building lateral as needed.
C. The method of connection of the building lateral to the street lateral
shall be approved by the Sewer District. After installation of the
street lateral has been approved, the new street lateral shall become
the property of the Sewer District. Any subsequent repairs to the
new street lateral shall then be made by the Sewer District at the
District's expense.
If, in the judgment of the Sewer District, it is determined
that a building lateral, without a property line cleanout, needs repair
or replacement, the Sewer District may install a cleanout at the property
line, at the property owner's expense, to allow maintenance of
the street lateral independently of the building lateral.
Any existing street lateral which, upon examination by the Sewer
District, is determined to be in need of replacement, will be replaced
with a new street lateral by the Sewer District at no cost to the
property owner.
A. The applicant for the building lateral permit shall notify the Sewer
District 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 Sewer District.
B. The applicant for the street lateral permit shall notify the Sewer
District 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 Sewer District.
When trenches are excavated for the laying of building laterals
or for street laterals, such trenches shall be inspected by the Sewer
District. Before the trenches are backfilled, the person performing
such work shall notify the Sewer District when the laying of the building
lateral is completed. No backfilling of trenches shall begin until
the inspection is completed.
A. All excavations for constructing building laterals shall be adequately
protected with barricades and lights so as to protect the public from
hazard.
B. Sheeting, bracing and shoring of trenches shall be provided as necessary
to protect adjacent structures, including poles, trees, pavements
and pipelines, and to provide safe working conditions.
C. The methods to maintain the stability of banks must be in accordance
with applicable laws, rules and regulations and are the sole responsibility
of the person performing the work.
Streets, sidewalks and other public property disturbed in the
course of the work shall be restored in a manner satisfactory to the
Sewer District. When installation requires disturbance of paved public
roads and shoulders, restoration shall be in accordance with requirements
of the authority having jurisdiction of such roads.
An interior cleanout fitting shall be provided for each building
lateral at a readily accessible location inside the basement wall.
The fitting shall contain a 45° branch with removable plug or
test tee positioned so that sewer cleaning equipment can be inserted
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 Sewer District. The property owner shall
indemnify the Sewer District from any loss or damage that may be directly
or indirectly associated with the installation of the building and
street laterals and connections and appurtenances.
