Determined from suitable samples taken at the control manhole provided or other control point authorized by the approving authority.
(c) 
BOD and suspended solids shall be determined from composite sampling.
(d) 
The city may select an independent firm or laboratory to determine flow, BOD and suspended solids.

(2000 Code, sec. 25-105)
(a) 
If the volume or character of the waste to be treated by the city does not cause overloading of the sewage collection, treatment, or disposal facilities of the city, then, prior to approval, the city and the person making the discharge shall enter into an agreement which provides that the discharger pay an industrial waste charge to be determined from the schedule of charges.
(b) 
If the volume or character of the waste to be treated by the city requires that wastewater collection, treatment, or other disposal facilities of the city be improved, expanded or enlarged in order to treat the waste, then, prior to approval, the city and the person making the discharge shall enter into an agreement which provides that the discharger pay in full all added costs the city may incur due to acceptance of the waste.
(c) 
The agreement entered into pursuant to subsection (a) of this section shall include but not be limited to:
(1) 
Amortization of all capital outlay for collecting and treating the waste, including new capital outlay and the proportionate part of the value of the existing system used in handling and treating the waste; and
(2) 
Operation and maintenance costs, including salaries and wages, power costs, costs of chemicals and supplies, and proper allowances for maintenance, depreciation, overhead, and office expense.
(2000 Code, sec. 25-107)
Industrial waste charges shall be separate and in addition to customary commercial sewer charges and shall be based upon the strength of the waste above that of the normal domestic wastewater. The industrial waste charges shall be calculated by the following formula:
S = Va (BOD - 250 mg/l + Vb (SS - 250 mg/l) + Vc (FOG - 100 mg/l) + (Vd)*
Where:
S
=
Surcharge expressed in dollars per month for waste containing excess strength.
V
=
Monthly waste flow expressed in million gallons.
BOD
=
Actual biochemical oxygen demand expressed in mg/l measured at customer’s point of discharge.
SS
=
Actual suspended solids expressed in mg/l measured at customer’s point of discharge.
FOG
=
Actual fats, oils and grease expressed in mg/l measured at customer’s point of discharge.
a
=
Unit cost expressed in dollars for removing 1 mg/l BOD from 1 million gallons.
b
=
Unit cost expressed in dollars for removing 1 mg/l SS from 1 million gallons.
c
=
Unit cost expressed in dollars for removing 1 mg/l FOG from 1 million gallons.
d
=
Unit cost expressed in dollars for transporting 1 million gallons of waste.
* “Vd” portion of the formula shall be used only when a new sewer main (and lift station, if required) must be constructed in order to adequately serve the customer due to volume of flow.
(2000 Code, sec. 25-108)
(a) 
The city shall adjust charges at least annually to reflect changes in the characteristics of wastewater based on the results of sampling and testing.
(b) 
Increases in charges shall be retroactive for two (2) billing periods and shall continue for six (6) billing periods unless subsequent tests determine that the charge should be further increased.
(c) 
The city shall review at least annually the basis for determining charges and shall adjust the unit treatment cost in the formula to reflect increases or decreases in wastewater treatment costs based on the previous year’s experience.
(d) 
The city shall bill the discharger by the month and shall show industrial waste charges as a separate item on the regular bill for water and sewer charges. The discharger shall pay monthly in accordance with practices existing for payment of sewer charges.
(2000 Code, sec. 25-109)
