or storm sewers that would cause a violation of the municipality's
WPDES permits and any modifications thereof.
F.
Special arrangements. No statement contained in this chapter shall
be construed as prohibiting any special agreement between the approving
authority and any person whereby a waste of unusual strength or character
may be admitted to the wastewater treatment facilities, either before
or after pretreatment, provided that there is no impairment of the
functioning of the wastewater treatment facilities by reason of the
admission of such wastes, and no extra costs are incurred by the approving
authority without recompense by the person, and further provided that
all rates and provisions set forth in this chapter are recognized
and adhered to.
G.

sewer system will be allowed only if there is available capacity in
all of the downstream public sewers, stormwater facilities, and wastewater
treatment facilities.
A.
Submission of basic data. The approving authority may require each
person who discharges or seeks to discharge industrial wastes to a
public sewer to prepare and file with the approving authority, at
such times as it determines, a report that shall include pertinent
data relating to the quantity and characteristics of the wastes discharged
to the wastewater treatment facilities. In the case of a new connection,
the approving authority may require that this report be prepared prior
to making the connection to the public sewers.
B.
Industrial discharges. If any waters or wastes are discharged or
are proposed to be discharged to the public sewers, which waters or
wastes contain substances or possess the characteristics enumerated
in § 5-2-2, and which in the judgment of the approving authority
have a deleterious effect upon the wastewater treatment facilities,
processes, equipment or receiving waters, or which otherwise create
a hazard to life, health, or constitute a public nuisance, the approving
authority may:

Measurement of flow. The volume of flow used for computing sewer
service charges shall be the metered water consumption of the person
as shown in the records of meter readings maintained by the Water
Department or Utility except as noted in § 5-2-3E, Metering
of waste.
E.
Metering of waste. Devices for measuring the volume of waste discharged
may be required by the approving authority if this volume cannot otherwise
be determined from the metered water consumption records. Metering
devices for determining the volume of waste shall be installed, owned,
and maintained by the person discharging the wastewater. Following
approval and installation, such meters may not be removed without
the consent of the approving authority.
F.
Waste sampling.
(1)
Industrial wastes discharged into the public sewers shall be subject
to periodic inspection and a determination of character and concentration
of said wastes. The determination shall be made by the industry as
often as may be deemed necessary by the approving authority.
(2)
Samples shall be collected in such a manner as to be representative
of the composition of the wastes. The sampling may be accomplished
either manually or by the use of mechanical equipment acceptable to
the approving authority.
(3)
Installation, operation, and maintenance of the sampling facilities
shall be the responsibility of the person discharging the waste and
shall be subject to the approval of the approving authority. Access
to sampling locations shall be granted to the approving authority
or its duly authorized representatives at all times. Every care shall
be exercised in the collection of samples to ensure their preservation
in a state comparable to that at the time the sample was taken.
G.
Pretreatment.
(1)
Persons discharging industrial wastes into any public sewer may be
required to pretreat such wastes, if the approving authority determines
pretreatment is necessary to protect the wastewater treatment facilities
or prevent the discharge of incompatible pollutants.
(2)
In that event, such person shall provide, at his expense, such pretreatment
or processing facilities as may be determined necessary to render
wastes acceptable for admission to the sanitary sewers.
H.
Grease, oil, and sand interceptors. Grease, oil, and sand interceptors
shall be provided when, in the opinion of the approving authority,
they are necessary for the proper handling of liquid wastes containing
floatable grease in amounts in excess of those specified in this chapter,
or any flammable wastes, sand, or other harmful ingredients, except
that such interceptors shall not be required for private living quarters
or dwelling units. All interceptors shall be of a type and capacity
approved by the approving authority and shall be located as to be
readily and easily accessible for cleaning and inspection. In maintaining
these interceptors, the owner(s) 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 approving authority. Disposal of the
collected materials performed by owner's(s') personnel or currently
licensed waste disposal firms must be in accordance with currently
acceptable Department of Natural Resources (DNR) rules and regulations.
I.
Analyses.
(1)
All measurements, tests, and analyses of the characteristics of waters
and wastes to which reference is made in this chapter shall be determined
in accordance with the latest edition of "Standard Methods" and with
the federal regulations of 40 CFR Part 136, Guidelines Establishing
Test Procedures for the Analysis of Pollutants, as amended from time
to time. Sampling methods, location, time, durations, and frequencies
are to be determined on an individual basis subject to approval by
the approving authority.
(2)
Determination of the character and concentration of the industrial
wastes shall be made by the person discharging them, or the person's
agent, as designated and required by the approving authority. The
approving authority may also make its own analyses on the wastes,
and these determinations shall be binding as a basis for sewer service
charges.
J.
Submission of information. Plans, specifications, and any other pertinent
information relating to proposed flow equalization, pretreatment,
or grease and/or sand interceptor facilities shall be submitted for
review and approval of the approving authority prior to the start
of their construction if the effluent from such facilities is to be
discharged into the public sewers. No construction of such facilities
shall commence until said approval has been granted.
A.
Sewer users served by water utility water meters. There is hereby
levied and assessed upon each lot, parcel of land, building, or premises
having a connection with the wastewater collection system and being
served with water solely by the Water Utility a sewer service charge
based, in part, on the quantity of water used, as measured by the
Water Utility water meter used upon the premises.
B.
Sewer users served by private wells.
(1)
If any person discharging wastewater into the public sanitary sewers
procures any part or all of his water from sources other than the
Water Utility, all or part of which is discharged into the sanitary
sewers, the person shall have water meters installed by the Water
Utility at the person's expense for the purpose of determining the
volume of water obtained from these sources. Where sewer meters are
already installed, new water meters will not be required. The water
meters shall be furnished by the Water Utility and installed under
its supervision, all costs being at the expense of the person requiring
the meter.
(2)
The Water Utility will charge for each meter a rental charge set
by the Water Utility to compensate for the cost of furnishing and
servicing the meter. The rental charge shall be billed at the time
the sewer service charge is billed.
C.
Deduct meters. If a user feels that a significant amount of metered
water does not reach the sanitary sewer, a customer may avail himself
of one of the following options:
(1)
He may request the approving authority to have such additional meters
or metered services installed as are necessary to calculate the volume
of water not discharged to the sanitary sewer (i.e., a "deduct" meter),
or he may request the approving authority to have a meter installed
to measure the actual amount of sewage discharged to the sanitary
sewer (i.e., a "sewage" meter). Requests for a second meter or metered
services must be made, in writing, to the approving authority. In
the event the approving authority agrees to such installations, the
customer shall be charged all costs attendant thereto, including,
but not limited to, a meter yoke for each meter (to be installed by
a licensed plumber); meter rental (the meter will be owned by the
customer and subject to access and inspection by the City personnel
at all times) in an amount set annually by the approving authority;
remote reading device(s) if necessary; and labor and miscellaneous
parts and supplies. No provision shall be made, nor shall any means
be taken, to route water from any deduct meter to the customer's general
distribution system. In addition to the general penalties set forth
in § 5-2-9, any violation of this chapter will result in
nullification of the deduct readings and removal of the deduct meter.
(2)
In the event it is physically impractical or impossible to install
metering equipment, he may request the approving authority to take
such means as it deems necessary to formulate an estimate of the amount
of water not being discharged into the sanitary sewerage system or,
conversely, the amount of actual sewage discharged thereto.
