Sec. 22-263. Charges for sewage service.

. . .

    (b)     The monthly charges for residential and public authority customer classifications shall be based on the average monthly billing of water usage during the immediate preceding calendar months of January, February and March. Where such basis is not considered representative of sewage discharge for public authority customers, the provisions of section 27-19 of this Code or any other reasonable basis of estimating sewage discharge from such customers may be used. Commercial and industrial charges shall be based on one hundred (100) percent of the monthly metered water used, except as otherwise provided in this Code.

Ccf = 100 cubic feet

    (2)     Extra strength charge. Wastewater discharged to the wastewater system from commercial or industrial users shall be subject to an extra strength charge when the BOD or total suspended solids concentration exceeds three hundred (300) milligrams per liter (mg/l) by weight. All analyses shall be performed on composite samples collected at no less than hourly intervals over a twenty-four-hour period.
Extra strength charges shall be calculated based on one hundred (100) percent of metered water use, except as otherwise provided in section 22-269 of this Code, in accordance with the following formula:

S = Vs × 0.00624 × [$ 0.120 0.124 (BOD - 300) + $0.0817 0.0850 (SS - 300)]

Where:


S

BOD
=
BOD strength index in mg/l by weight.
300
=
Allowed BOD and suspended solids strengths in mg/l by weight.
$ 0.0817 0.0850
=
Unit charge for suspended solids in dollars per pound; of which $ 0.0629 0.0654 represents the user charge portion and $0.0188 0.0196 represents capital charges.

=
Suspended solids strength index in mg/l by weight.
