[Amended 10-4-1999; 6-2-2008; 2-5-2018]
A. Normal sewage service charge.
(1) There is hereby levied and assessed upon each lot or parcel of land
with a building having a lateral available to discharge normal sewage
to the public sewer system a wastewater service charge based upon
rates established by the Common Council of the City of Montello. Said
charges shall be assessed and collected monthly.
(2) If commercial or industrial customers obtain all or any part of their
water from sources other than the public water utility, all or any
part of which is discharged into the public sewers, the customer shall
be required to have a water meter or meters installed for the purpose
of determining the volume of water obtained from these other sources.
Should the Committee determine that the water usage is too small to
justify a meter, the Committee shall have the authority to waive this
requirement, and a flat rate shall be charged based on estimated water
usage and the metered rate schedule. The water meters shall be furnished
by the Sewer Utility and installed by the customer. All other costs
in connection with the water meter installation shall be at the expense
of the customer. The Sewer Utility will charge for each meter at the
rate of 50% of the minimum service charge set for that size meter
to compensate for furnishing, reading and servicing the meter. This
charge shall be in addition to the wastewater service charge.
(3) If residential customers obtain all or part of their water from sources
other than the public water utility all or any part of which is discharged
into the public sewers, a flat rate charge shall be paid for wastewater
service. Should the Committee determine that the minimum flat rate
charge is less than the charge would be on a metered basis, the Committee
shall have the authority to set a higher rate based on estimated total
usage and the metered rate schedule. Should the residential customer
request it, a water meter shall be installed and the customer shall
be charged on the same basis as commercial or industrial customers
having private water supplies.
B. Minimum charge.
(1) The minimum monthly charge wastewater service charge shall be based
on the size water meter in service, as per the following schedule:

water service:

D. Industrial and commercial charges for other than normal wastewater.
(1) Charges for wastewater other than normal wastewater shall be based on flow, BOD, suspended solids, and such other constituents which affect the cost of collection and treatment. Charges shall be made in accordance with rates established by the Common Council of the City of Montello as set forth in Subsection
D(3) below.
(2) All persons discharging wastes into the public sewers are subject to a surcharge, in addition to any other wastewater service charge, if their wastewater has a concentration greater than normal concentration (see definition in §
272-1). The volume of flow used for computing waste surcharge shall be the metered water consumption, subject to adjustments as otherwise herein provided, or the actual volume of waste as determined by an industrial waste metering installation, The amount of surcharge shall reflect the cost incurred by the Sewer Utility in removing BOD, suspended solids, and other pertinent constituents.
(3) Rates of surcharge. The rates of surcharge for each of the aforementioned
constituents will be at the prevailing rate at the time. Said prevailing
rates at this time are as follows:
(a)
For BOD (in excess of 200 mg/l):
[1]
Operation and maintenance (includes replacement): $0.27 per
pound.
[2]
Debt service: $0.14 per pound.
[3]
Total surcharge: $0.41 per pound.
(b)
For suspended solids (in excess of 250 mg/l):
[1]
Operation and maintenance (includes replacement): $0.18 per
pound.
[2]
Debt service: $0.08 per pound.
[3]
Total surcharge: $0.26 per pound.
(4) In addition to the above surcharges, the Sewer Utility's costs
of sampling and analyzing industrial wastes shall be charged to the
applicable industry.
(5) Where industrial wastes are of such a strength or magnitude or are
delivered over such a period of time that the above surcharges do
not reflect the actual cost of treatment to the Sewer Utility, the
Utility reserves the right to establish a special charge for handling
the waste. That portion of the charge related to capital investment
shall be based on the design capacity required for the particular
waste. In no event shall the charges be less than those charges determined
by applying the above surcharge.
In the event that the Utility provides pretreatment
of industrial wastes, the entire cost of such pretreatment shall be
charged to the person producing the industrial wastes. The costs shall
include but not be limited to capital expenditures, operation and
maintenance expenses, labor, chemicals, heat and power.
Nothing in this article shall prohibit the City
from providing wastewater services to persons outside the corporate
limits of the City under mutually agreeable conditions.
An audit of the Utility's financial standing
shall be made biannually. This audit will be used to review the adequacy
of the then existing rates, and said rates shall be adjusted if necessary
to provide sufficient revenues to adequately finance the Utility's
operation in accordance with the original intent of the rate structure.
The biannual audit and review shall also be used to ensure that each
recipient of sewage service (or user class) is charged in proportion
to the cost of providing said recipient (or user class) with sewage
service. Excess revenues collected for operation and maintenance from
a class of users shall be applied to the costs of operation and maintenance
attributable to that class of users in the next year and the rates
shall be adjusted accordingly.
All charges under this article which are not
paid within 20 days of billing date are subject to a late payment
charge of 3% of the net billing.
Annual income from the wastewater service charges
which constitute funds required for replacement shall be separately
accounted for and shall not be utilized for any purposes other than
replacement.
Each billing shall identify the amount billed
which is attributable to sewer service.
The accidental discharge of a prohibited waste
into any sewer shall be reported to the Committee by the person responsible
for the discharge, or by the owner or occupant of the premises where
the discharge occurs, immediately upon obtaining knowledge of the
fact of such discharge so that steps may be taken to minimize its
effect on the treatment plant.
In the event that a person discharging wastes
into the public sewers produces evidence satisfactory to the Committee
that a significant amount of the total annual volume of water used
for all purposes does not reach the sanitary sewer, the person may
be permitted to have an exemption water meter(s) installed. Said meter(s)
shall be furnished by the Committee and installed by the customer.
All other costs shall be at the expense of the person requiring the
meter(s), including any piping revisions required to ensure that only
water not reaching the sanitary sewer is metered by the exemption
meter. The Committee will charge for each meter at the rate of 25%
of the minimum service charge set for that size meter to compensate
for furnishing, reading, and servicing the meter. This charge shall
be in addition to the wastewater service charge. The amount of exemption
water metered shall be subtracted from the total amount of water used
by the person to determine the applicable wastewater service charge.
No unauthorized person shall maliciously, willfully,
or negligently break, damage, destroy, uncover, deface, or tamper
with any structure, appurtenance, or equipment which is a part of
the wastewater facilities. Any person(s) violating this provision
shall be subject to immediate arrest under charge of disorderly conduct.
Each disposer granted Montello approval and
permit pursuant to this article agrees to release, protect and indemnify
Montello, to hold and save Montello harmless, and to defend Montello,
its officers, employees, agents and representatives from any and all
claims, demands, causes of action, judgments, costs, expenses, damages
or other liability, including but not limited to damages from injury
or death and damages to persons or property arising out of the activities
permitted under this approval and permit and/or arising out of the
activity or conduct of such disposer or its equipment. Montello shall
require each applicant for Montello approval and permit to provide
Montello a certificate of insurance adequate in Montello's judgment
to permit the licensed disposer to comply with the provisions of this
section. Notice of any changes in or discontinuance of the insurance
shall be provided at least three weeks before the effective date thereof.
