ad valorem taxes which are attributable to the operation and maintenance
of the waste treatment system.
(d) Disposition of excess revenues.
The city will apply
excess revenues collected from a class of users to the cost of operation
and maintenance attributable to that class for the next year and adjust
the rate accordingly.
(e) Rates.
(1) The user charge system shall provide for the equitable distribution
of debt service, reserve, and operation and maintenance costs of the
sanitary sewerage system to each user, or user class. The minimum
base fixed rate per domestic user per month for readiness to serve
and disposal of up to 2,000 gallons of normal domestic waste measured
as potable water taken from the city waterworks shall be calculated
from the sum of annual debt service; an annual reserve in the amount
of ten percent of annual debt service, until an amount equal to one
annual debt service payment is accumulated; and seventy percent of
annual operations and maintenance, less interest and depreciation;
divided by the current number of users, and then divided by twelve
months.
(2) The over minimum base rate per thousand gallons for waste disposal
measured as potable water, up to eleven thousand gallons, taken from
city waterworks, per user per month, shall be calculated from thirty
percent of annual operation and maintenance costs, less interest and
depreciation, divided by the average number of thousands of gallons
of water used, above two thousand gallons, per user per month, during
the months of December, January and February, and then divide by twelve
months.
(3) Over minimum base rate per thousand gallons, charge limited to eleven
thousand gallons shall apply to domestic users only.
(4) An industrial waste charge shall be made on persons discharging industrial
wastes into the city sewerage system. The charges for the several
constituents shall be additive, applied to both the minimum base fixed
rate and the over minimum base rate per thousand gallons, and calculated
with the base by the sum of the following applicable factors plus
one, and multiplied by the appropriate base rate:
(A) For BOD in excess of 250 mg/l, BOD of discharge minus 250, divided
by 250.
(B) For COD in excess of 375 mg/l, COD of discharge minus 375, divided
by 375.
(Ordinance 147, sec. 16, adopted 6/22/92)

or damage to their property by city employees and against liability
claims and demands for personal injury or property damage asserted
against the person(s) and growing out of the sampling operation.
(d) The superintendent and other duly authorized employees of the city
bearing proper credentials and identification are entitled to enter
all private properties through which the city holds a negotiated easement
for the purpose of:
(1) Inspection, observation, measurement, sampling or repair;
(2) Maintenance of any portion of the sewerage system lying within the
easements; and
(3) Conducting any other authorized activity.
All activities shall be conducted in full accordance with the
terms of the negotiated easement pertaining to the private property
involved.

any processes including metallurgical, chemical, oil refining, ceramic,
paper or other industries beyond that point having a direct bearing
on the kind and source of discharge to the public sewers.

process are released to the sewer potentially causing accelerated
deterioration of these structures or interfering with proper conveyance
and treatment of waste;
(2) A governmental agency informs the city that the effluent from the
waste treatment plant is no longer of a quality permitted for discharge
to a watercourse, and it is found that the customer is delivering
waste to the city’s system that cannot be sufficiently treated

(b) If service is discontinued pursuant to subsection
(a)(2) of this section, the city shall:
(2) Supply the customer with the governmental agency’s report and
provide the customer with all pertinent information; and
(3) Continue disconnection until such time as the customer provides pretreatment/additional
pretreatment or other facilities designed to remove the objectionable
characteristics from his wastes.
