[Rev. Ords. 1989, § 19-110]
(a)
No person shall discharge or cause to be discharged any wastes into
a public sewer unless the acceptance of these wastes has been approved
by the commission. The commission requires 45 days' prior notification
by any person of the proposed substantial change in volume or character
of pollutants over that being discharged into the wastewater treatment
works or of a proposed new discharge into the wastewater treatment
works of pollutants from any source discharging more than 2,000 gallons
per day.
(b)
The commission shall be notified by the owner of the proposed discharge
of water from a swimming pool to the public sewer. The commission
shall have the right to approve or deny the request, to designate
the time and rate of flow permitted and to enter upon the premises
to inspect the project prior to and during the operation. If an owner
fails to provide such notification or disregards instruction, whether
accidentally or intentionally, the owner will be held responsible
for any damage that may be caused from such discharge subject to the
enforcement powers contained in this article, and the commission shall
not be held liable for such violation.
[Rev. Ords. 1989, § 19-111]
No person shall discharge into or put into any public sewer
or drain of the town, or into any sewer, drain or fixture which thereafter
discharges into any public sewer, drain or appurtenance thereof, any
wastes or substance other than such kinds or types of water or water-carried
wastes for the conveyance of which the particular sewer, drain or
appurtenance is intended, designed or provided.
[Rev. Ords. 1989, § 19-112]
Except as specifically provided with reference to some particular
sewer, sanitary sewers shall be used only for the conveyance and disposal
of sanitary sewage and for diluted, water-carried industrial wastes
which are not objectionable as hereinafter provided. No sanitary sewer
shall be used to receive and convey or dispose of any stormwater or
surface water, subsoil drainage, any large continuous flow of water
seeping into buildings or excavations from soils or other underground
sources, flows of natural springs or groundwaters, surplus from flowing
wells, or the discharges from roofs, roof conductors, yard drains,
or street or highway drains. Cooling water or uncontaminated process
water shall also be excluded, except that the superintendent upon
a finding of special circumstances may permit their discharge into
a sanitary sewer.
[Rev. Ords. 1989, § 19-113]
Stormwater and all other unpolluted drainage shall be discharged
into storm sewers or to a natural outlet approved by the superintendent.
Industrial cooling water or unpolluted process waters may be discharged
upon approval by the commission to a storm sewer or natural outlet.
However, no material, the discharge of which into natural streams,
ponds, lakes or other natural bodies of water is prohibited by state
or federal law or regulations, shall be discharged into any storm
sewer.
[Rev. Ords. 1989, § 19-114]
(a)
If the proceedings for the layout and construction of any particular
sewer or for its acquisition by the town did not indicate what kind
of sewer or drain it was to be or what wastes could or could not be
discharged therein, the superintendent shall consider the pertinent
facts and shall determine what kind of sewer or drain the sewer is
to be considered for the application of the provisions of this article
and what waste or wastewaters shall be permitted to be discharged
thereinto or be excluded therefrom.
(b)
The fact that wastes have been discharged into a particular sewer
which was not intended or designated for that purpose shall not create
a right to continue to discharge unless permitted by this article.
[Rev. Ords. 1989, § 19-115]
No person shall discharge or cause to be discharged any of the
following described waters or wastes to any public sewers:
(1)
Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive
liquid, solid or gas.
(2)
Any waters containing toxic or poisonous solids, liquids or gases
in sufficient quantity, either singly or by interaction with other
wastes, to injure or interfere with any waste treatment process, constitute
a hazard to humans or animals, create a public nuisance or create
a hazard in the receiving waters of the wastewater treatment plant.
(3)
Any waters or wastes having a pH lower than 5.5 or higher than 10.0,
or having any other corrosive property capable of causing damage or
hazard to structures, equipment and personnel of the wastewater works.
(4)
Solid or viscous substances in quantities or of such size capable
of causing obstruction to the flow in sewers or other interference
with the proper operation of the wastewater facilities, such as, but
not limited to, ashes, bones, cinders, sand, mud, straw, shavings,
metal, glass, rags, feathers, tar, plastics, wood, unground garbage,
whole blood, paunch manure, hair and fleshings, entrails and paper
or plastic dishes, cups, milk containers, etc., either whole or ground
by garbage grinders.
[Rev. Ords. 1989, § 19-116]
The following described substances, materials, waters or wastes
shall be limited in discharges to public sewers to concentrations
or quantities which will not harm either the sewers, wastewater treatment
process or equipment, will not have an adverse effect on the receiving
stream or will not otherwise endanger lives, limb, or public property
or constitute a nuisance. The commission may set limitations lower
than the limitations established in the regulations below if in its
opinion such more severe limitations are necessary to meet the above
objectives. In forming its opinion as to the acceptability, the commission
will give consideration to such factors as the quantity of subject
waste in relation to flows and velocities in the sewers, materials
of construction of the sewers, the wastewater treatment process employed,
capacity of the wastewater treatment plant, degree of treatability
of the waste in the wastewater treatment plant and other pertinent
factors. The limitations or restrictions on materials or characteristics
of waste or wastewaters discharged to the sanitary sewer which shall
not be violated without approval of the commission are as follows:
(1)
Wastewater having a temperature higher than 150° F. (65°
C.).
(2)
Wastewater containing more than 25 milligrams per liter of petroleum
oil, nonbiodegradable cutting oils, or products of mineral oil origin,
or containing substances which may solidify or become viscous at temperatures
between 32° F. and 150° F. (0° and 65° C.).
(3)
Wastewater containing floatable oils, fat or grease.
(4)
Notwithstanding the provisions of § 19-319, wastewater shall not contain any garbage, either whole or properly shredded or ground. Garbage grinders shall not be connected to sanitary sewers from homes, hotels, institutions, restaurants, hospitals, catering establishments, or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers. Garbage grinders so connected at the time of the passage of this amendment may continue to be utilized but may not be replaced.
(5)
Any waters or wastes containing strong acid iron pickling wastes
or concentrated plating solutions, whether neutralized or not.
(6)
Any waters or wastes having concentrations of objectionable or toxic
substances, including, but not necessarily limited to, those in excess
of the limits listed below, or wastes exerting an excessive chlorine
requirement to such degree that any such material received in the
composite sewage at the wastewater treatment works exceeds the limits
established by the commission as necessary after treatment of the
composite sewage to meet the requirements of the state, federal or
other public agencies of jurisdiction for such discharge to the receiving
waters.

[Rev. Ords. 1989, § 19-117]
(a)
If any waters or wastes are discharged or are proposed to be discharged to the public sewers which waters contain the substances or possess the characteristics enumerated in § 19-417 and which in the judgment of the commission may have a deleterious effect upon the wastewater facilities, processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the commission may:
(1)
Reject the wastes;
(2)
Require pretreatment to an acceptable condition for discharge
to the public sewers;
(3)
Require control over the quantities and rates of discharge;
and/or
(4)
Require payment to cover added cost of handling and treating
the wastes not covered by existing sewer use charges under the provisions
of this article.
(b)
If the commission permits the pretreatment or equalization of waste
flows, the design and installation of the plants and equipment shall
be subject to the review and approval of the commission and/or other
regulatory agencies.
[Rev. Ords. 1989, § 19-118]
In determining whether any waste discharged or proposed to be
discharged into any public sewer or drain is or is not to be excluded
under these rules and regulations or under any appropriate ordinance,
consideration shall be given to the quantity, time or times, rate
and manner of discharge, dilution and character of the waste in question,
the size of the sewer or drain into which it is or is to be discharged,
the probable quantity of other sewage in the sewer or drain at the
time of discharge, the quantities of other objectionable wastes likely
in the sewer or drain and other pertinent facts. Minute quantities
of a waste which would be objectionable in larger quantity may be
permitted if sufficiently diluted when and as discharged or if the
quantity discharged is very small in comparison to the receiving sewer
or drain and the flow therein at the time of discharge upon specific
permission from the superintendent, but any permission to discharge
minute quantities of an otherwise excluded waste shall be revocable
at any time by the superintendent.
[Rev. Ords. 1989, § 19-119]
The admission into the public sewers of any waters or wastes
having a five-day biochemical oxygen demand greater than 200 milligrams
per liter or containing more than 200 milligrams per liter of suspended
solids or containing any quantity of substances having undesirable
characteristics or a chlorine demand greater than 15 milligrams per
liter or having an average daily flow greater than 2% of the average
daily flow to the wastewater treatment works shall be subject to review
and approval by the superintendent. Where necessary in the opinion
of the superintendent and with concurrence by the commission, the
owner shall, at his expense, provide such pretreatment as may be necessary
to reduce objectionable characteristics or constituents to within
the maximum limits provided for in this article, or control the quantities
and rates of discharge of such waters or wastes. Plans, specifications
and any other pertinent information relating to proposed pretreatment
facilities shall be submitted to the commission and no construction
of such facilities shall be commenced until said approval is obtained
in writing.
[Rev. Ords. 1989, § 19-120]
Where pretreatment or flow-equalizing facilities are provided
or required for any waters or wastes, they shall be maintained continuously
in satisfactory and effective operation by the owner at his expense.
[Rev. Ords. 1989, § 19-121]
When required by the commission, the owner of any property serviced
by a building sewer carrying industrial waste shall install a suitable
structure together with such necessary meters and other appurtenances
in the building sewer to facilitate observation, sampling and measurement
of the wastes. Such structure when required shall be accessibly and
safely located and shall be constructed in accordance with plans approved
by the commission. The structure shall be installed by the owner at
his expense and shall be maintained by him so as to be safe and accessible
at all times.
[Rev. Ords. 1989, § 19-122]
(a)
Grease, oil and sand removal facilities, traps, etc., shall be provided when in the opinion of the commission they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts as specified in § 19-417(3) or any flammable wastes, sand or other harmful ingredients, except that such facilities shall not be required for private living quarters or dwelling units. All facilities shall be of a type and capacity approved by the commission and shall be located so as to be readily accessible for cleaning and inspection. In the maintaining of these facilities the owner shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal, which are subject to review by the commission. Any removal and hauling of the collected materials not performed by owner personnel must be performed by currently licensed waste disposal firms. Grease traps shall be required for all commercial properties, more specifically, restaurants, food dispensing and processing establishments and grocery stores, serviced by or connected to the public sewer system of the town. All such traps shall be of tank system design with a unit installed separate and apart from kitchen drains, except, where it is impossible to install such tanks due to existing plumbing, land area and location of buildings in relation to sewer lines, such grease traps shall be installed having minimum sizes of 100 pounds per kitchen or 25 pounds per sink.
(b)
At all premises where wastes or substances specified to be excluded
from sewers or drains by this article are customarily present and
liable to be discharged directly or indirectly into any public sewer
or drain, suitable and sufficient piping layouts, oil or grease traps
or separators, screens, sedimentation chambers, diluting devices,
storage and regulating treatment, cooling or condensing equipment
and similar devices or equipment shall be provided, maintained and
operated by the owner to ensure that no waste, substance, or water
required to be excluded from the sewer or drain shall be discharged
thereinto in violation of the requirements of this article. All facilities
shall be of a type and capacity approved by the commission and shall
be located as to be readily and easily accessible for cleaning and
inspection. In the maintaining of these facilities the owner shall
be responsible for the proper removal and disposal by appropriate
means of the captured material and shall maintain records of the dates
and means of disposal, which are subject to review by the commission.
Any removal and hauling of the collected materials not performed by
owner personnel must be performed by currently licensed waste disposal
firms.
(c)
At premises where any of the substances or wastes prescribed as being
or to be excluded from any sewer or drain are present and liable to
be discharged contrary to the limitations of this article, the superintendent
may require that the owner of the premises provide, operate and maintain
a sampling well or wells, a flow-measuring device, manholes, catchbasins
or other suitable devices or treatment facilities on any or all sewer
service lines or drains from the premises near the point where the
drains connect to any public sewer or drain. By means of the sampling
well or wells or other devices, the owner, owners and occupants of
the premises and the superintendent or any public officer charged
with any duty involving the supervision of the disposal of wastewaters
may secure samples of or examine the wastes and waters discharged
into the public sewer or drain and measure the quantities for the
purpose of ascertaining compliance or noncompliance with the requirements
of this article. Such facilities, when required, shall be accessibly
and safely located and shall be constructed in accordance with plans
approved by the commission. The facilities or devices shall be installed
by the owner at his/her expense and shall be maintained by him/her
so as to be safe and accessible at all times.
[Rev. Ords. 1989, § 19-123]
Cesspool and septic tank cleanings may be discharged to the wastewater facilities at the septic waste dumping station designated and in a manner approved by the commission. The composition of these wastes shall be subject to those limitations enumerated in § 19-417, with no industrial wastes, wastes considered to be detrimental to the treatment process, or wastes from chemical tanks permitted. Hauling and unloading of cleanings shall be performed by currently licensed waste disposal contractors. Unloading shall be made according to the arrangements and methods designated by the commission and the area shall be cleaned after each unloading. An unloading slip shall be turned in to the superintendent's office for each unloading. The slips provided by the town shall show the date, time, hauler's name, origin of load, capacity of truck, approximate gallons being unloaded, names and addresses where collected and signature of the driver. The capacity of the contractor's truck may be calculated by the commission, and any part of a load will be billed as a full load. The commission may assess such fees or charges as it may deem reasonable and proper for the acceptance, handling and treating of such wastes.
[Rev. Ords. 1989, § 19-124]
(a)
Any real estate or real property in the town which is serviced by
or is connected to the public sewer system of the town, and is part
of the water district of the town or serviced by town water, shall
have its sewer service charge based on the water flow meter set and
maintained on the water supply line by the water district.
(b)
Any real estate or real property in the town which is serviced by
or is connected to the public sewer system of the town and is not
part of the water district of the town or serviced by town water shall
have a water flow meter set and maintained on the water supply line
from the well or wells to the property. The meter shall be installed
by the town and so set as to measure all the water passing through
the pipe. Cost of the meter, together with the cost of installation
thereof, shall be borne by the property owner. The real estate's or
real property's sewer service charge shall be based on the water flow
registered on the meter.
(c)
Where feasible, and with the approval of the commission, any real
estate or real property located in the town which is serviced by or
is connected to the public sewer system of the town and regularly
utilizes quantities of water that are not returned through the town
sewer system may be equipped with a timing device, either electrical
or mechanical, connected to the effluent pump if properly so equipped,
or some similar device, to measure or approximate all flow, and all
sewer service charges will be adjusted accordingly to reflect actual
flow as accurately as possible.
(d)
All meters, excepting those referred to in subsection (a) of this section, shall be set in places approved by the sewer commission, and all changes of location shall be made under their supervision or their agent's supervision.
(e)
The property owner, excepting those referred to in subsection (a) of this section, shall be responsible for all damages to the meter or timing device from frost, heat, or steam, or negligence on his part, or that of his agents or the occupants of such property, and the meter or timing device shall be maintained by him so as to be safe and accessible at all times.
(f)
If any meter or timing device fails to register correctly, the property
owner shall be charged at the rate of average daily use, as shown
by the meter or timing device when in proper order.
[Rev. Ords. 1989, § 19-125]
All measurements, tests and analyses of the characteristics
of waters and wastes to which reference is made in these rules and
regulations shall be determined in accordance with the latest edition
of "Standard Methods for the Examination of Water and Wastewater,"
published by the American Public Health Association. Sampling methods,
location, times, duration, and frequencies are to be determined on
an individual basis subject to approval by the commission.
[Rev. Ords. 1989, § 19-126]
No statement contained in this article shall be construed as
preventing any special agreement or arrangement between the commission
and any concern whereby a waste of unusual strength or character may
be accepted by the commission for treatment; provided that such agreements
do not contravene any requirements of existing federal laws and are
compatible with any user charge and industrial cost recovery system
in effect.
[Rev. Ords. 1989, § 19-127]
All industries discharging into a public sewer shall perform
such monitoring of their discharge as the commission and/or other
duly authorized employees of the town may reasonably require, including
installation, use and maintenance of monitoring equipment, keeping
records and reporting the result of such monitoring to the commission.
Such records shall be made available upon request by the commission
to other agencies having jurisdiction over discharges to the receiving
waters.
