It is determined and declared to be necessary and conductive 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.
This Chapter shall have precedence over any terms or conditions of agreements or contracts between the City and users (including industrial users, special districts or other municipalities) which are inconsistent with the requirements of the Clean Water Act.
[R.O. 2009 §13.22.020; Ord. No. 4719 §3, 3-6-1989]

[R.O. 2009 §13.22.030; Ord. No. 4719 §3, 3-6-1989]
The purpose of this Chapter is to generate adequate annual revenues to pay costs of annual operation and maintenance including replacement and costs associated with debt retirement of sewer revenue bonds which the City may by ordinance designate to be paid by the user charge system. The accounts described in this Article may be modified and maintained in accordance with the bond ordinance, as long as the intent of this user charge system ordinance is met.
[R.O. 2009 §13.22.040; Ord. No. 4719 §3, 3-6-1989]
All revenue collected as a result of this Chapter shall be deposited in the Sewer Revenue Fund. The current expenses of the sewer system shall be paid from month to month as a first (1st) charge against the Sewer Revenue Fund as the expenses become due. Current expenses shall include all reasonable and necessary costs of operating, repairing, maintaining and insuring the sewer system, but shall exclude payments into the Sinking Fund, Bond Reserve Fund and Replacement Fund. If a shortage occurs in the Sewer Revenue Fund, the user charges shall be increased to provide the revenue needed. An estimate of the annual expenses associated with the sewer system is included in Appendix A (which is on file in City offices). These expenses are estimates and may change in the future.
Principal and interest on the sewer revenue bond shall be paid from the Sinking Fund. So long as any bonds thereof are outstanding, an amount equal to one-twelfth (1/12) of the annual debt service, including principal and interest, shall be deposited in the Sinking Fund monthly.
As long as any of the principal or interest of the sewer revenue bonds remains unpaid, at least one thousand dollars ($1,000.00) per month shall be deposited in the Bond Reserve Fund until the amount of ninety-four thousand dollars ($94,000.00) is accumulated.
After all payments and credits described above have been made and to the extent of monies then remaining in the Sewer Revenue Fund, there will next be paid credited to the Replacement Fund the sum of one thousand dollars ($1,000.00) each month.
[R.O. 2009 §13.22.050; Ord. No. 4719 §3, 3-6-1989]
Each user shall pay for the services provided by the Board of Municipal Utilities based on his/her use of the treatment works as determined by water meter(s) acceptable to the Board.
For residential contributors, monthly user charges shall be based on the rate per thousand gallons of metered water usage. For the billing period consisting of meter readings taken after October first (1st) and prior to July first (1st) the consumption as registered on the water meter shall be the basis for determining the sewer service fee. For the billing periods represented by the meter readings taken after July first (1st) and prior to October first (1st), (those bills having due dates of August twentieth (20th) and September tenth (10th) and October tenth (10th) respectively), the sewer service fee shall be determined by applying the applicable rate to the average water consumption derived from the prior nine (9) months or the actual consumption whichever is less.
The average water consumption shall be determined by taking the sum of the water consumption of the number of months available and dividing it by the number of months. The number of months available include a maximum of the nine (9) billings prior to the July first (1st) reading date.
In order for the average to be established, a consumer must be billed for at least one (1) month's service, of which the billing period shall not be less than thirty (30) days.
A consumer's average is established at each residence he/she may occupy. An average established at one (1) residence will not be used as a basis for billing at subsequent residences.
If a consumer occupies a residence during the average period (i.e., during the meter reading period of July first (1st) through October first (1st), his/her sewer service fee for the first (1st) month's billing will be based on actual water consumption for that billing period. Any subsequent billings during the average period also will be based on the first (1st) month's consumption.
For industrial and commercial contributors, user charges shall be based on matter 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 a wastewater meter(s) or separate water meter(s) installed and maintained at the contributor's expense and in a manner acceptable to the Board of Municipal Utilities.
Each contributor shall pay a basic user charge rate of ninety-two cents ($0.92) per one thousand (1,000) gallons of water (or wastewater) as determined in the preceding Section. Refer to Appendix A (which is on file in the City offices) for details on rate and charge computations.
Commercial or industrial users shall be subject to an excessive strength charge in addition to the basic sewer service charge when the BOD or SS concentrations of a discharge exceeds three hundred (300) or three hundred fifty (350) milligrams per liter (mg/l) respectively. All analyses shall be performed on composite samples collected over a twenty-four (24) hour period.
The excessive strength charge shall be assessed as follows:
[R.O. 2009 §13.22.060; Ord. No. 4719 §3, 3-6-1989]
The Board of Municipal Utilities shall conduct sampling and analytical testing of the discharge from commercial and industrial wastewater producers in the City for the purpose of determining excessive strength charges. The monitoring shall be done on a monthly basis for those commercial and industrial entities that have exhibited excessive strength discharges in any of the three (3) previous months. The monitoring frequency for users without excessive strength discharge for three (3) months will restore the normal frequency established in the pretreatment Chapter.
Extra strength charges will be assessed at the normal billing time for water and wastewater. The BOD and SS values used in the above formula shall be those observed during the applicable water and wastewater billing period.
In addition to the basic sewer service charge and any excessive strength charge, the Board of Municipal Utilities shall charge all monitored users the actual cost incurred for composite sampling and analytical testing of that user's discharge during the current billing period.
[R.O. 2009 §13.22.070; Ord. No. 4719 §3, 3-6-1989]
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 responsible plant operating personnel and approved by the Board of Municipal Utilities.
[R.O. 2009 §13.22.080; Ord. No. 4719 §3, 3-6-1989]
The user charge rates established in this Article apply to all users, regardless of their location of the City's treatment works.
[R.O. 2009 §13.22.090; Ord. No. 4719 §3, 3-6-1989]
All users shall be billed monthly. Under normal circumstances all bills shall be mailed the last working day of the month and bear a due date of the tenth (10th) of the month following the month in which they were mailed.
Twenty (20) days after the date the bills are mailed, a five percent (5%) late payment shall be assessed on the outstanding balance of the user charge. Any bill not paid on or before the date the late penalty is assessed shall have its water and/or sewer service discontinued until such bill is paid.
[R.O. 2009 §13.22.100; Ord. No. 4719 §3, 3-6-1989]
The Board of Municipal Utilities will review the user charge system as it deems necessary and revise user charge rates as necessary to ensure that the system generates adequate revenues to pay all costs and that the system continues to provide for the proportional distribution of costs among users and user classes.
[R.O. 2009 §13.22.110; Ord. No. 4719 §3, 3-6-1989]
The Board of Municipal Utilities will notify each user at least annually in conjunction with a regular bill of the rate being charged.
