The user charge system and hereinafter set forth has been developed from data outlined in the report of Willett, Hofmann and Associates, Inc., dated August, 1976, entitled “Sewer User Charge System for Treatment of Municipal and Industrial Wastes,” this report being incorporated herein by reference and which shall constitute the basis for determining industrial and domestic user charges.
('72 Code, § 51.060) (Ord. 51-A, passed 10-4-76) Penalty, see § 51.999
(A) The wastewater service charges for the use of and for services supplied by the wastewater facilities of the city shall consist of a basic user charge for operation and maintenance plus replacement, a debt service charge and a surcharge, if applicable.
(B) The debt service charge shall have a fixed charge component and a usage charge component. The debt service charge shall be computed by dividing 40% of the total annual debt service of all outstanding revenue bonds by the number of users. Through further divisions, the monthly and quarterly debt service fixed charges can be computed. The debt service usage charge shall be computed by dividing 60% of the total annual debt service of all outstanding revenue bonds by the total annual metered volume on a cost per 100 cubic feet basis.
(C) The basic user charge shall be based on water usage as recorded by water meters and sewage meters for wastes having the following normal volume and concentrations:
(1) Flow of 150,000 cubic feet per quarterly period.
(2) A five day, 20°C biochemical oxygen demand (BOD) of 200 mg/l.
(3) A suspended solids content of 240 mg/l.
(D) It shall consist of operation and maintenance costs plus replacement and shall be computed as follows:
(1) Estimate the projected annual revenue required to operate and maintain the wastewater facilities, including a replacement fund, for the next fiscal year for all works categories.
(2) Proportion the estimated costs to wastewater facility categories by volume, suspended solids, BOD5.
(3) Estimate waterworks volume, pounds of SS, and pounds of BOD5 to be treated.
(4) Compute unit costs for volume (dollars per HCF) for SS (dollars per pound) and for BOD5 (dollars per pound.).
(5) Compute costs per HDF for volume, SS, and BOD5 at normal sewage strength. Add these costs to determine the charge for operation and maintenance including replacement.
(E) A surcharge will be levied upon all users whose wastes exceed the normal concentrations for BOD (200 mg/l) and SS (240 mg/l) and for volume (150,000 cubic feet quarterly). The surcharge will be based on water usage as recorded by water meters and sewage meters for all wastes which exceed the 200 mg/l, 240 mg/l concentrations for BOD, and SS content respectively. Section 51.106 specifies the procedure to compute a surcharge.
(F) The wastewater service charge shall be reviewed annually by certified public accountants to the city in their annual audit report. It shall be revised periodically to reflect a change in debt service or a change in operation and maintenance including replacement costs.

Cross-reference:
Computation of surcharge, see § 51.106
(A) The volume of flow used for computing basic user charges and surcharges shall be the metered water consumption read to the lowest even increments of 100 cubic feet.
(B) If the person discharging wastes into the public sewers procures any part, or all, of his or her water from sources other than the public waterworks system, all or a part of which is discharged into the public sewers, the person shall install and maintain, at his or her expense, water meters of a type approved by the Operator for the purpose of determining the volume of water obtained from these other sources.
(C) Devices for measuring the volume of waste discharged may be required by the Operator if these volumes cannot otherwise be determined from the metered water consumption records.
(D) Metering devices for determining the volume of waste shall be installed, owned, and maintained by the person. Following approval and installation, the meters may not be removed without the consent of the Operator.
('72 Code, § 51.062) (Ord. 51-A, passed 10-4-76; Am. Ord. 19-03, passed 5-6-19)
(A) A minimum debt service charge of $17.00 per month shall be applied to all single metered users. The minimum charge shall allow the use of 165 cubic feet per month, as measured by the water meter.
(B) A debt service rate charge of $4.50 per 100 cubic feet in excess of the first 165 cubic feet per month shall be applied to all single metered users of the sewer service. The meter reading shall be to the nearest cubic foot of water used.
(C) A minimum debt service charge of $17.00 shall be applied to each unit in a multiple unit user which is served through a single meter. By way of example, the calculation for the minimum charge for a four-unit apartment building is as follows: $17.00/unit x 4 units = $68.00.
(D) (1) A debt service rate charge of $4.50 per 100 cubic feet shall be applied to all usage in excess of 165 cubic feet per unit in a multiple unit user per month. The meter reading shall be to the nearest cubic foot of water used. The usage in excess of 165 cubic feet per unit is calculated as follows for a four-unit apartment building:
[Usage in cubic feet - (165 cubic feet/unit x 4 units)] x $4.50/100 cubic feet
(2) If the month’s usage is less than the 165 cubic feet per unit then only the minimum debt service charge shall apply.
(E) For a definition of “multiple unit user,” see § 52.090.
(F) The multiple unit user status shall only be permitted for existing circumstances and nothing herein shall be construed to permit future multiple unit user situations.
('72 Code, § 51.063) (Ord., passed 5-4-87; Am. Ord., passed 12-21-87; Am. Ord., passed 8-1-88; Am. Ord. 98-06, passed 6-15-98; Am. Ord. 03-01, passed 3-3-03; Am. Ord. 09-02, passed 3-16-09; Am. Ord. 10-10, passed 6-21-10)
There is established a minimum charge and a basic user rate for the use of and for service supplied by the wastewater facilities of the city to be applied separately to single metered or multiple unit premises served:
(A) A minimum charge of $8.05 per month shall be applied to all single metered users. The minimum charge shall allow the use of 165 cubic feet per month, as measured by the water meter.
(B) A basic user rate of $2.15 per 100 cubic feet in excess of the first 165 cubic feet per month shall be applied to all single metered users of the sewer service. The meter reading shall be to the nearest cubic foot of water used.
(C) A minimum charge of $8.05 shall be applied to each unit in a multiple unit user which is served through a single meter. The minimum charge shall allow the use of 165 cubic feet per unit per month. For example, the calculation for the minimum charge for a four-unit apartment building is as follows: $8.05/unit x 4 units = $32.20.
(D) (1) All usage in excess of 165 cubic feet per unit in a multiple unit user per month as measured by the water meter shall be billed at the rate of $2.15 per 100 cubic feet. The meter reading shall be to the nearest cubic foot of water used. For example, the usage in excess of 165 cubic feet per unit is calculated as follows for a four-unit apartment building:
[Usage in cubic feet - (165 cubic feet/unit x 4 units)] x $2.15/100 cubic feet.
(2) If the month’s usage is less than 165 feet per unit then only the minimum charge shall apply.
(E) All nonmetered residential users of the wastewater facilities shall pay a minimum flat monthly charge of $58.30 to cover the cost of the minimum debt service charge, debt service rate charge of $4.50 per 100 cubic feet, the minimum service charge and the basic user rate of $2.15 per 100 cubic feet. The flat rate charge shall allow a maximum of 665 cubic feet as follows:
(1) Minimum debt service charge $17.00 per month;
(2) Debt service to 665 cubic feet at
$4.50 per 100 cubic feet
over minimum allowance of
165 cubic feet per month $22.50 per month;
(3) Minimum basic service charge $8.05 per month;
(4) Basic service to 665 cubic feet
at $2.15 per 100 cubic feet over
minimum allowance of 165 cubic
feet per month $10.75 per month;
(5) Total flat rate $58,30 per month.
(F) Commencing on October 1, 2015, and continuing until May 1, 2025, the basic user rate shall be increased annually by $0.50 in the following manner:
Period | Minimum Charge for 165 Cubic Feet per Month | Basic User Rate per 100 Cubic Feet in Excess 165 Cubic Feet per Month | Minimum Flat Monthly Charge for Non-Metered Residential Users (Allows for 665 Cubic Feet) |
Period | Minimum Charge for 165 Cubic Feet per Month | Basic User Rate per 100 Cubic Feet in Excess 165 Cubic Feet per Month | Minimum Flat Monthly Charge for Non-Metered Residential Users (Allows for 665 Cubic Feet) |
