It is determined and declared to be necessary and conducive to the protection of the public health, safety, welfare and convenience of the City to collect charges from all users who contribute Wastewater to the City's Treatment Works. The proceeds of such charges so derived will be used for the purpose of operating, maintaining and retiring the debt for such public Wastewater Treatment Works.
[Ord. No. 1194 Art. II §§1-11, 1-28-1985]

[Ord. No. 1194 Art. III §§1-3, 1-28-1985]
The user charge system shall generate adequate annual revenues to pay costs of annual operation and maintenance including replacement and costs associated with debt retirement of bonded capital associated with financing the Treatment Works which the City may by ordinance designate to be paid by the user charge system. That portion of the total user charge which is designated for operation and maintenance including replacement of the Treatment Works shall be established by this Chapter.
That portion of the total user charge collected which is designated for operation and maintenance including replacement purposes as established in Section 710.040, shall be deposited in a separate non-lapsing fund known as the Operation, Maintenance and Replacement Fund and will be kept in two (2) primary accounts as follows:
An account designated for the specific purpose of defraying operation and maintenance costs (excluding replacement) of the Treatment Works (Operation and Maintenance Account).
An account designated for the specific purpose of ensuring replacement needs over the useful life of the Treatment Works (Replacement Account). Deposits in the Replacement Account shall be made at least annually from the Operation, Maintenance and Replacement Revenue in the amount of three thousand one hundred dollars ($3,100.00) annually.
Fiscal year-end balances in the Operation and Maintenance Account and the Replacement Account shall be carried over to the same accounts in the subsequent fiscal year, and shall be used for no other purposes than those designated for these accounts. Monies which have been transferred from other sources to meet temporary shortages in the Operation, Maintenance and Replacement Fund shall be returned to their respective accounts upon appropriate adjustment of the user charge rates for operation, maintenance and replacement. The user charge rates shall be adjusted such that the transferred monies will be returned to their respective accounts within the fiscal year following the fiscal year in which the monies were borrowed.
[Ord. No. 1194 Art. IV §§1-6, 1-28-1985]
Each user shall pay for the services provided by the City based on his use of the Treatment Works as determined by water meters acceptable to the City.
Wastewater for residence shall be charged on the basis of the average monthly water usage for the months of January, February, and March. This basis shall be reestablished each year. All other users shall be charged based on their monthly water usage.
[Ord. No. 2168 §1, 7-10-2013]
[Ord. No. 2168 §§1—2, 7-10-2013]
Unit charges shall be prorated.
Minimum charge (per user, per billing, regardless of use): Ten dollars and twenty-six cents ($10.26).
Residential and commercial user unit charge (per 1,000 gallons): Three dollars and seventeen cents ($3.17).
Initial residential charges shall be based on a monthly water usage of five thousand (5,000) gallons per month.
(Reference is made to Section 710.070). 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. The surcharge for operation and maintenance including replacement is:
Any user which discharges any toxic pollutants which causes 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 responsible plant operating personnel and approved by the Board of Aldermen.
The user charge rates established in this Section apply to all users, regardless of their location, of the City's Treatment Works.
[Ord. No. 1194 Art. VI §§1-2, 1-28-1985]
The City will review the user charge system at least every two (2) years, and revise user charge rates as necessary to ensure that the system generates adequate revenues to pay the costs of operation and maintenance including replacement and that the system continues to provide for the proportional distribution of operation and maintenance including replacement costs among users and user classes.
The City will notify each user at least annually, in conjunction with a regular bill, of the rate being charged for operation, maintenance including replacement of the Treatment Works.
[Appendix A to Ord. No. 1194]
This Section presents the methodology to be used in calculating user charge rates and surcharges and illustrates the calculations followed in arriving at the first (1st) year's 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 certainly they will change as time passes. Therefore, the unit costs must be re-established whenever necessary to reflect actual expenses and loadings. Once the system is in use, the expenses and loadings can be determined from operating records and the unit costs can be adjusted based on these figures.
Expenses. The total annual expenses associated with the Treatment Works, as defined in Section 710.020, are estimated as follows:
Allocation of Expenses. The total operation and maintenance including replacement expense is allocated to the appropriate pollutants in the following manner.
The initial hydraulic loading is estimated to be 51,300,000 gallons per year.
The initial BOD loading is estimated to be 74,000 pounds per year.
The initial SS loading is estimated to be 81,000 pounds per year.
[Appendix B to Ord. No. 1194]
This Section contains a Replacement Schedule that was developed to determine the amount of revenue needed to fund the Replacement Account. 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 (including an allowance for inflation) over the useful life of the treatment works. Also listed is the estimated cash flow that will occur in the Replacement Account. 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 Account shall be adjusted accordingly.
