[Amended 11-8-1999 by Ord. No. 29-1999]
A. Surcharge rate.
(1) Purpose. Nothing contained in this section shall be construed as prohibiting any special agreement or arrangement between the City and any person or municipality whereby industrial waste of unusual strength or character may be admitted into the sewerage system by the City subject to payment of a surcharge therefor by such person or municipality or by proper and continuous pretreatment prior to discharge into the sewerage system. The surcharge shall be based on present invested capital costs and operating costs.
(2) Additional charges for strong wastes. There shall be additional charges for nondomestic wastes, discharged to the POTW from any industry business or commercial enterprise and having BOD5, TSS and/or NH3-N in excess of the average BOD5, TSS and/or NH3-N of normal domestic sewage. Normal domestic sewage shall be defined as having the following concentration:
(a) BOD5: 300 mg/l.
(b) TSS: 325 mg/l.
(c) NH3-N: 20 mg/l.
(3) Surcharge formula. In order to determine the additional charge for nondomestic wastes with strength greater than that of normal domestic sewage, the following formula shall be used:
7
SQ = 0.00834 Q1 [(BOD5-300) TA + (TSS1-325) TB ÷ (NH3-N1-20) TC]
Where:
SQ is the quarterly surcharge to be added to the quarterly sewer rental charge.
0.00834 is a constant to convert waste strength expressed in mg/l to thousand pounds of waste.
Q1 is the quarterly volume of nondomestic wastewater flow expressed in millions of gallons.
BOD5 is the five-day biochemical oxygen demand of the nondomestic wastewater expressed in mg/l.
TSS1 is the total suspended solids in mg/l of the nondomestic wastewater.
NH3-N1 is the ammonia, expressed as nitrogen in mg/l, of the nondomestic wastewater.
300, 325 and 20 are constants expressing wasteload strength of domestic waste in mg/l for the respective pollutant parameters.
TA represents the cost incurred by the City in treating 1,000 pounds of BOD5. TB represents the cost of treating 1,000 pounds of total suspended solids. TC represents the cost incurred by the City in treating 1,000 pounds of ammonia. TA, TB and TC vary each year as treatment plant operation and maintenance costs change. Therefore, TA and TB and TC shall be determined at the beginning of each calendar year by the City based upon budgeted operating costs, and adopted by ordinance by the City; see Chapter 212, Fees.
When a value of BOD5 and/or total suspended solids and/or ammonia of a nondomestic waste is less than 300, 325, and 20 mg/l, respectively, the value of 300, 325, and 20 mg/l, respectively, shall be used in the calculation of the strong waste discharge in place of the actual value which is less than 300, 325, and 20 mg/l, respectively.
(4) Said surcharge rates shall be effective February 1, 2000, and shall be applied to the first quarter 2000 surcharge bills, which surcharge rates shall be as follows:
8
Rate effect:
Parameter | Cost Represented in Formula by | Costs per 1,000 Pounds Rate for Period First Quarter 2000 |
BOD5 | TA | $126.90 |
TSS | TB | $116.71 |
NH3-N | TC | $1,281.69 |
Hereafter, the Director of Public works is authorized to increase surcharge rates annually based on audited financial statements.
B. Septage rates. Septage haulers or any other person disposing of sanitary or other waste into the sewage system of the City at designated points as herein provided shall pay a dumping fee to include the following charges:
(1) Testing fee for each and every delivery to the City of Reading's wastewater treatment system.
(2) Per-gallon treatment charge based on the rated capacity of the waste delivery vehicle.
(3) Per-gallon surcharge based on the rate capacity of the waste delivery vehicle as payment for excessive BOD5, total suspended solids, and total dissolved solids common to septic waste.
(4) The rates shall be revised annually at the beginning of each year by the City by ordinance; see Chapter 212, Fees.
