[Ord. No. 2072 Art. III, 5-6-2003; Ord. No. 2227 §1, 12-20-2005]
The user charge system shall generate adequate annual revenues to pay the costs of annual operation and maintenance including replacement and cost 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 Section.
Operation And Maintenance. That portion of the total user charge collected which is designated for the operation and maintenance, including replacement, purposes as established in Section 703.040 shall be deposited in a separate non-lapsing fund known as the Sewer Service Operation, Maintenance and Replacement Fund. Funds will be kept in four (4) primary accounts as follows:
The Operation and Maintenance Account shall be an account designated for the specific purpose of defraying operation and maintenance costs, excluding replacement, of the treatment works. Deposits in the Operation and Maintenance Account shall be made at least monthly from the operation and maintenance revenue sufficient to equal the approved annual operating budget for the operation and maintenance of the wastewater treatment works. "Operations and maintenance" shall be defined as the total sewer fund budget exclusive of plant and equipment replacement expenses, debt retirement expenses and Capital Reserve Fund contributions as defined in Section 703.030 (B)(2 — 4)
The Replacement Account shall be an account designated for the purpose of ensuring replacement needs over the useful life of the treatment works. Deposits in the Replacement Account shall be made at least annually from the replacement revenue in an amount sufficient to equal the amount budgeted for equipment replacement expenses in the approved annual budget for the Sewer Fund.
The Debt Service Account shall be an account designated for the purpose of paying the costs of debt retirement. Deposits shall be made at least annually from the operation revenue sufficient to cover the annual costs of debt retirement.
The Sewer Debt Reserve and Sewer Depreciation Accounts shall be maintained as required by existing bond ordinances until such debt is fully retired. These accounts are fully funded and will require no further deposits unless funds are removed from them prior to the retirement of the bonds.
Fiscal year-end balances in all accounts listed in Subsection (B) shall be carried over to the same accounts in each 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 any of the accounts listed in Subsection (B) shall be returned to their respective accounts upon appropriate adjustment of the user charges 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 in which the monies were borrowed.
[Ord. No. 2072 Art. IV, 5-6-2003; Ord. No. 2227 §2, 12-20-2005; Ord. No. 2290 §1, 10-3-2006; Ord. No. 2306 §§1 — 3, 12-19-2006; Ord. No. 2374 §§1 — 3, 11-6-2007; Ord. No. 2454 §§1 — 3, 12-2-2008]
Each user shall pay for the services provided by the City based on that user's use of the treatment works as determined by water meters acceptable to the City.
For residential contributors, monthly user charges will be based on average monthly water usage for periods ending during the months of January, February and March. If a residential contributor has not established a January, February and March average, their monthly bill shall be the median charge of all other residential contributors.
For industrial and commercial contributors, user charges shall be based on water used during the current month. 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 wastewater meter(s) or separate water meter(s) installed and maintained at the contributor's expense and in a manner acceptable to the City. If a commercial or industrial contributor can demonstrate through use history and the nature of the enterprise that increased summer usage is due to watering and does not contribute to sewer usage, this commercial or industrial contributor may elect the winter averaging method if so approved by the authorized personnel of the City.
The minimum charge per month shall be thirteen dollars and seventy-seven cents ($13.77). The minimum charge shall apply to all properties connected to the sewer system regardless of water consumption. In addition, each contributor shall pay a user charge for operation and maintenance, including replacement, of sixty-five and one-tenths cents ($0.651) per one hundred (100) gallons of water as determined in the preceding Section.
[Ord. No. 2513 §1, 12-15-2009; Ord. No. 2727 §1, 1-21-2014; Ord. No. 2797 §1, 1-20-2015; Ord. No. 2835 §1, 1-19-2016; Ord. No. 2882 § 1, 1-17-2017]
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:
[Ord. No. 2513 §2, 12-15-2009; Ord. No. 2727 §2, 1-21-2014; Ord. No. 2797 §1, 1-20-2015; Ord. No. 2835 §2, 1-19-2016; Ord. No. 2882 § 2, 1-17-2017]
$0.8303 per pound BOD
$0.7141 per pound SS
Any user which discharges any toxic pollutants which cause an increase in the cost of managing the effluent of 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 Chapter apply to all users of the City's treatment works regardless of the user's location.
Rate Structure — Residential — Commercial. If a user experiences exceptionally high or low usage during any month in the period from which the average is taken, appropriate City personnel may, at their discretion, substitute an average calculated from at least three (3) other more typical months for each of the months in which the exceptional usage occurred. This provision shall allow the adjustment of the yearly rate to more fairly reflect actual usage for the year, where unusual usage has occurred during the averaging period due to events such as leaks and prolonged winter absences. The City shall not be obligated to make adjustments for periods in which readings do not vary by at least fifty percent (50%) above or below the average for that customer as determined by the City.

All users shall be billed monthly by either the City or a duly authorized billing agent for the City. Billings for each month shall be made within thirty (30) days after the end of the billing period. Payments are due when billings are made.
[Ord. No. 2072 Art. VI, 5-6-2003]
The City shall review the user charge system annually 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 and maintenance, including replacement, of the treatment works.
