Except as specifically noted herein, residential, commercial, and those industrial customers not participating in the industrial cost recovery program, shall pay sewage service rates based on water purchased from the City. Industries participating in industrial cost recovery shall be charged on metered waste flows. The rates and charges for sewer service furnished by the City shall be based insofar as possible on the number of gallons of water used in each month and are hereby fixed and established on a monthly basis, as follows:
(A) (1) All customers other than wholesale customers beyond the City limits shall be billed eleven and 63/100 dollars ($11.63) per month, based on water usage, for each one thousand (1,000) gallons of water consumption. The minimum sewer bill for all customers shall be twenty-three and 26/100 dollars ($23.26) per month, based on water usage of two thousand (2,000) gallons (or less) in each month.
(2) Wholesale customers beyond the city limits shall, as a minimum, be billed for operation, maintenance and replacement costs of the sewer system. The sewer rate for wholesale customers beyond the city limits shall be three and 75/100 dollars ($3.75) per one thousand (1,000) gallons based on readings of a wastewater meter.
(B) (1) Surcharge. A surcharge will be levied on any customer discharging above twenty five (25) milligrams per liter ammonia nitrogen, two hundred fifty (250) milligrams per liter BOD and three hundred (300) milligrams per liter suspended solids. The charge will be eighty nine cents ($0.89) per pound of ammonia nitrogen, twenty nine cents ($0.29) per pound of BOD and eighteen center ($0.18) per pound of suspended solids.
(2) Method of Billing Surcharges. The excessive strength surcharge shall be based on the following formula, with the total applied to the monthly bill of affected users:
Payment ($/month)
(A(D-250) + B(E-300) + C(F-25)) x .00834 x G = Surcharge
Where formula components are as follows:
(A) Surcharge rate for BOD, in $/pound.
(B) Surcharge rate of SS, in $/pound.
(C) Surcharge rate for ammonia nitrogen in $/pound.
(D) User's average BOD concentration, in mg/l.
(E) User's average SS concentration, in mg/l.
(F) User's average ammonia nitrogen concentration, in mg/l.
(G) User's monthly flow to sewage works, per 1,000 gallons.
(3) No reduction in sewage service charges, fees, or taxes shall be permitted because of the fact that certain wastes discharged to the sewage works contain less than mg/l of BOD, mg/l of SS or mg/l of ammonia nitrogen.
(C) For residential, industrial, institutional and commercial users, monthly user charges will be based on actual water usage. If a residential, industrial, institutional or commercial user has a consumptive use of water, or, in some other manner, uses water which is not discharged into the wastewater collection system, the user charge for that contributor may be based on readings of a wastewater meter(s) or separate water meter(s) installed and maintained at the user's expense.
(D) Sewer rates for large consumers:
(1) For consumers who purchase between $4,500,000 and 7,000,000 gallons of water per month, the sewer rate for that month shall be $9 per 1,000 gallons (one unit);
(2) For consumers who purchase more than 7,000,000 gallons of water per month, the sewer rate for that month shall be $6.75 per 1,000 gallons (one unit); and
(3) The sewer rates set forth in this section shall not be available to water districts, wholesale customers or municipalities.
