No connection of private property or public
property with the sewer system shall be made until the owner of the
land, or his duly authorized agent, has made application in writing
to the Director for permission to make the same, and has been granted
such permission.
A. There shall be two classes of sewer permits, one for
residential and commercial service, and one for service to establishments
producing industrial wastes. In either case, the owner shall apply
using the forms furnished by the Town. The sewer permit application
shall be supplemented by any plans, specifications or other information
considered pertinent in the judgment of the Director.
B. A sewer inspection fee will be required and shall
be paid according to the current fee schedules maintained by the Sewer
Department and established by the Town Council.
C. Final authorization of the sewer permit application
will be given by the Director, upon inspection and approval of installation,
by a duly licensed plumber or drainlayer.
D. Where a cut in the road is required, an application
to excavate a highway shall be obtained from the Public Works office.
E. A plumbing permit shall be required for any interior
plumbing changes that may be necessary. This permit is available through
the Plumbing Inspector's office.
A separate and independent building sewer shall
be provided for every building. Where one building stands at the rear
of another on an interior lot and no private sewer is available or
can be constructed to the rear building through an adjoining alley,
court, yard or driveway, the building sewer from the front building
may be extended to the rear building and the whole considered as one
building sewer. The Town does not and will not assume any obligation
or responsibility for damage caused by or resulting from any such
single connection aforementioned. The rights appurtenant to such single
connection or extension from a front building to a rear building shall
be recorded with each of the respective deeds.
An investigation of private sewers or drains
and sewer service connections within the street limits laid prior
to November 19, 1985, may be made at the discretion of the Director
to determine if such private sewers and sewer connections are properly
located, laid at suitable gradient, in good condition, with proper
and suitable appurtenances and in every way satisfactory to the Director.
If, in the opinion of the Director an existing service connection
is significantly deficient in gradient, condition or appurtenances,
he may require the reconstruction of all or parts of the service connection.
Such reconstruction shall be completed within six months of the official
notification of the owner.
All costs and expenses incident to the installation
and connections or the reconstruction to correct deficiencies of the
building sewer shall be borne by the owner. The owner shall indemnify
the Town from any loss or damage that may directly or indirectly be
occasioned by the installation of the building sewer.
Any person developing a plat of land in the
Town shall at his own expense install wastewater works including sewer
lines and service stubs with wyes in such plat and shall connect the
same with the existing sewer system according to Town-approved plans
where the system is within 200 feet (60.6 m) of the subdivision. Where
the existing sewer system is beyond 200 feet (60.6 m) but the plat
is in its entirety or in part located in an area where there are immediate
plans to provide public sewers, the developer shall at his own expense
install wastewater works including sewer lines and service stubs with
wyes in such manner as to make future connection with the Town's sewer
system feasible. All work shall be carried out in accordance with
the standard construction details available from the Town Clerk. The
developer may, at his option, also build private wastewater disposal
systems in total compliance with division 2 of this chapter. If the
proposed development is located in an area where there are no immediate
plans to provide public sewers, each lot shall be designed insofar
as feasible to permit the location of an individual sewage disposal
system between the street and the house. Connection to the public
sewer system shall be in compliance with the terms and conditions
set forth in the following:
A. The entire cost of the installation of all wastewater
works to serve any such plat or any part thereof, shall be paid by
the developer. The entire cost shall include the cost of all engineering
services, both preliminary to and during the actual installation of
such sewer pipes, and other works, and the costs of all materials,
services, labor and supplies for constructing and laying out sewers
and connecting the same with the sewer system.
B. The developer, before proceeding with the installation
of sewer lines in any such plat or any part thereof, shall submit
plans and specifications to the Director relative to the proposed
construction in accordance with the Standard Construction Details
available from the Town Clerk. The proposed plans shall include a
minimum diameter transmission/collector line as determined by the
Director to allow sufficient capacity to carry sewage flows from abutting
properties and from properties abutting properties. Unless otherwise
approved, the minimum diameter transmission/collector line shall be
12 inches or two sizes above the minimum standard specification. If
the Planning Board, upon consideration of the Director's recommendation,
approves such plans and specifications, the developer shall submit
the name of a qualified contractor to do the work, together with a
breakdown of items, quantities and unit prices for the project. After
investigating the qualifications of the proposed contractor and reviewing
the breakdown submitted, the Director shall make the final determination
whether to allow the contractor to proceed or to request that another
contractor be submitted for approval.
C. The construction and laying out of all sewer lines
and other wastewater works pursuant to this section shall be subject
to the inspection of the Director. If at any time the Director shall
determine that the construction and laying out of such sewer lines
and other wastewater works is not being performed in accordance with
the plans and specifications as approved, he shall forthwith notify
the developer to this effect in writing, who shall then order the
suspension of all further work by the contractor until such corrections
are made as will produce complete compliance with the plans and specifications.
D. All wastewater works constructed pursuant to the provisions
of the preceding section shall become the property of the Town. After
such wastewater works have been connected with the public sewer, all
the normal costs of operating and maintaining them shall be borne
by the Town. However, the Town may backcharge the contractor and/or
the developer for any abnormal conditions for a period of six months
after acceptance.
E. Should a developer's plan include necessary pump stations,
as approved by the Director, the Town will be in a position of incurring
additional maintenance and replacement costs. Prior to construction
approval from the Director, the developer shall post a maintenance/replacement
fee of $25,000 per pump station with the Town.
The following design standards for sanitary
sewers are considered acceptable:
A. At the juncture between a sewer and one of larger
diameter, the inverts of the sewers shall be designed so that the
peak flow lines match.
B. Velocities greater than 12 feet per second (3.7 mps)
or less than two feet per second (0.61 mps) when flowing will be unacceptable,
except near ends of laterals.
C. Installing a smaller sewer downstream from a larger
sewer in general will be considered unacceptable.
D. Sewers of a diameter from eight inches (20.3 cm) through
21 inches (53.3 cm) shall be designed so that they are flowing at
a depth no greater than 0.6 times the diameter of the sewer at peak
flow rates.
E. Sewers of a diameter larger than 21 inches (53.3 cm)
shall be designed so that they are flowing at a depth no greater than
0.7 times the diameter of the sewer at peak flow rates.
F. Sewers shall be designed using a Manning's “n”
of 0.10 to 0.013 constant with depth, depending on material of the
sewer.
G. No public sewer shall be less than eight inches (20.3
cm) diameter, and all public sewers shall be constructed in streets,
easements or right-of-ways.
H. Manholes shall be installed at the end of each line;
at all changes in grade, size, or alignment; at all intersections;
and at distances not greater than 400 feet (121.4 m) or as approved
by the Director.
I. Manholes shall be constructed of precast reinforced
concrete, American Society for Testing and Materials Designation C478,
latest edition; concrete masonry units, ASTM designation C139, latest
edition; or as approved by the Director.
J. All sanitary sewers and appurtenances shall be designed
and constructed in accordance with WPCF Manual of Practice No. 9,
Design and Construction of Sanitary and Storm Sewers, latest revision,
and TR-16; Guides for the Design of Wastewater Treatment Works, as
prepared by the Technical Advisory Board of the New England Interstate
Water Pollution Control Commission.
K. Material specifications. The following pipe materials
shall be considered acceptable for the construction of sewers:
(1) Polyvinyl chloride (PVC) meeting the American Society
for Testing Materials (ASTM) specification D3034.
(2) Ductile iron (D.I.) meeting ASTM specification A746
with the internal surfaces cement-lined and the interior and exterior
surfaces bituminous coated.
(3) Vitrified clay (V.C.) meeting ASTM specification C700
extra-strength classification.
(4) Acrylonitrile-butadiene-styrene (ABS) meeting ASTM
specification D2751 with gasket-type joints.
Sewer service connections from the public sewer
to the street line shall be laid at such depth and gradient and in
such location as the Director may determine. No sewer service connection
shall serve more than one building, except by permission of the Director.
All pipe shall have compression joints. The following design standards
for buildings sewers, are considered acceptable:
A. The pipes for building sewers from the public sewer to the property line shall be six inches (15.2 cm) in diameter, but larger sizes may be required by the Director. The building sewer from the property line to the building drain shall be a minimum of four inches (10.2 cm) in diameter, but larger sizes may be required by the Director. All such pipes shall conform to §
207-37K. Building sewer pipes shall be laid with a minimum gradient of at least 1/4 inch per foot (2.1 cm/m), without 90° bends. The pipes shall be laid accurately to straight lines and gradients, except that junctions with public sewers shall be made at an angle, by installing a six-inch (15.2 cm) by six-inch (15.2 cm) wye or tee, such that flow from the building sewer shall be not opposite in direction to the flow in the public sewer. Where depth of the public sewer is such that a chimney is required, such chimney shall be installed per Town specifications. Special means for flushing and cleaning (cleanouts) in accordance with the particular requirements of the Director shall be provided in the building sewer at seventy-five-foot increments, at all significant changes in direction and as otherwise required by the Director. The connection of the building sewer into the public sewer shall be made at the wye or tee branch, if such branch is available at a suitable location. If no branch is available, a connection must be made by tapping the existing sewer by an approved method, then inserting an approved wye or tee saddle, all encased in concrete. Approval of tapping method and saddle shall be made by the Director.
B. No service pipes for other utilities, such as water,
gas and the like, whether Town-owned or privately owned, shall be
laid in the same trench with a building sewer, except by written approval
of the Director.
Whenever possible, the building sewer for new
buildings shall be brought to the building at an elevation below the
basement floor. In all buildings in which any building drain is too
low to permit gravity flow to the public sewer, sanitary sewage carried
by such building drain shall be lifted by means of a sewage pump,
and discharged to the building sewer, upon approval of the Director.
However, the Town shall have no responsibility for the operation and
maintenance of such equipment.
No person shall make or keep a connection of
roof downspouts, exterior foundation drains, areaway drains, or other
sources of surface runoff or groundwater to a building sewer or building
drain which in turn is connected directly or indirectly to a public
sewer.
The connection of the building sewer into the
public sewer shall conform to the requirements of the building and
plumbing code or other applicable rules and regulations of the Town
and/or the procedures set forth in appropriate specifications of the
ASTM and WPCF Manual of Practice No. 9, latest edition. All such connections
shall be made gastight and watertight. Any deviation from the prescribed
procedures and materials must be approved by the Director before installation.
All excavations for building sewer installation
shall be adequately guarded 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 Town.
The applicant for the building sewer permit
shall notify the Director when the building sewer is ready for inspection
and connection to the public sewer. The connection shall be made under
the supervision of the Director.
Whenever any user under this article shall cease
operation, notice shall be given to the Building Inspector and the
waste lines employed by such user shall be sealed under the supervision
of the Building Inspector.
