Sec. 2. User charges shall be based on actual water
used during the billing period. If actual
water use is not available, the user charge
will be based on prior water usage. New
customers shall have a first billing based
on an estimate determined by the Finance
Department.
If a commercial or industrial contributor
has a consumptive use of water, or in some
other manner uses water which is not
returned to the wastewater collection
system, the user charge for that
contributor may be based on a wastewater
meter(s) or separate water meter(s)
installed and maintained at the
contributor's expense, and in a manner
acceptable to the City.
Sec. 3. The minimum charge per billing period shall
be $3.25 and said minimum charge shall
include water usage of 400 cubic feet
during said billing period. In addition,
each contributor shall pay a user charge
rate for operation and maintenance
including replacement of $0.25 per 100
cubic feet of water (or wastewater) as
determined in the preceding section and an
additional $0.105 per 100 cubic feet of
water (or wastewater) for debt retirement
for all water used in excess of 400 cubic
feet per billing period.
Reference is made to Appendices A and B,
attached hereto and made a part of this
ordinance, for the purpose of showing the
method of calculating the sewer user
charge. As provided in Article III,
Section 7, above, a replacement charge
shall be included in the user charge when
the new water pollution control plant is
constructed and operable.
Sec. 4. For those contributors who contribute
wastewater, the strength of which is
greater than normal domestic sewage, a
surcharge in addition to the normal user
charge will be collected.

Sec.
5. Any user which discharges any toxic
pollutants which cause an increase in the
cost of managing the effluent or the sludge
from the City's treatment works, or any
user which discharges any substance which
singly or by interaction with other
substances causes identifiable increases in
the cost of operation, maintenance, or
replacement of the treatment works, shall
pay for such increased costs. The charge
to each such user shall be as determined by
the Director of Public Works and approved
by the City Council by resolution.
Sec.
6. The user charge rates established in this
article apply to all users, regardless of
their location, of the City's treatment
works.
Sec.
7. Water not discharged into system. If any
user of water consumes water for any
purpose which does not cause discharge into
fi
the sanitary sewer system, and if approved
R
by the City and as established by a
separate water meter installed and
maintained by such user, the consumption of
such water can be determined, no charge
shall be made on the basis of water so
supplied. Residential contributors shall
not be allowed this option, unless approved
by the Finance Department.
Sec.
8. Water discharged into system from private
source. If any person shall discharge
water into the City sanitary sewer system
from private wells or other sources other
'

have the right to install a meter at the i
owner's expense to measure such flow or to

APPENDIX A TO USER CHARGE ORDINANCE N0. 81-3021
This appendix presents the methodology used in
calculating user charge rates and surcharges and
illustrates the calculations followed in arriving
at fiscal year 1982 user charges and surcharges.
The unit costs established in this appendix are
based on estimates of expenses and loadings. The
actual expenses and loadings that occur may differ
from these estimates and will change as time
passes. Therefore, the unit casts must be
reestablished whenever necessary to reflect actual
expenses and loadings. Once the new water
pollution control plant is in operation, the
expenses and loadings can be determined from
operating records and the unit costs can be
adjusted based on these figures.
1. Annual Expenses

TO
USER CHARGE ORDINANCE NO. 81-3021
CITY OF IOWA CITY, IOWA
This appendix (which will be prepared when the new
water pollution control plant is completed) contains
a replacement schedule that was developed to
determine the amount of revenue needed to provide
for the Replacement Fund. The replacement schedule
lists the equipment in the treatment works, the
estimated dates when the equipment will have to be
replaced, and the estimated cost of replacement over
the useful life of the treatment works. Also listed
is the estimated cash flow that will occur in the
Replacement Fund. The replacement dates and costs
shown are estimates; the actual replacement dates
and costs could be significantly different from
those shown. If the actual replacement expenses
differ significantly from those listed in the
replacement schedule, the funding of the Replacement
Fund shall be adjusted accordingly.
(The annual revenue required for the Replacement
Fund will be determined and the calculations
included in this appendix when the new water
Pollution control plant is completed. The annual
replacement revenue required will be inserted in
Appendix A, Step 1 of this ordinance.)

EPA REVIEW
Bob Stewart of EPA called this morning following his review of the Iowa City
user charge ordinance. There are two changes which must be made.
During our review of the ordinance with staff, we deleted certain sentences
from Sections 5 and 6 of Article III. These sentences must be restored to the
ordinance for EPA approval.
I
The following sentences must be added to the ordinance:
j At the end of Section 5: "The source of these transfers shall not be from
1 the Operation and Maintenance Fund."
At the end of Section 6: 'Operation and maintenance funds may not be used
for capital improvement projects."
t
We are enclosing an original and three copies of the.revised ordinance.
I Please destroy or vowprevious copies you may have.
