SQ = 0.00834 QI [(BODI - 200) TCBOD + (SSI - 300) TCSS + (DSI - 500) TCDS + (NH3NI - 25) TCNH3N] |
Where: | |||
1) | SQ is the quarterly surcharge to be added to the normal sewer rent. | ||
2) | 0.00834 is a constant to convert waste concentrations expressed in mg/l to thousands of pounds of waste. | ||
3) | QI is the quarterly industrial waste flow expressed in million gallons. | ||
4) | BODI, SSI, DSI and NH3NI are the respective concentrations of BOD5, suspended solids, dissolved solids and ammonia nitrogen of the industrial waste expressed in mg/l. | ||
5) | 200, 300, 500 and 25 are constants which express the waste load concentrations in mg/l for normal domestic wastes. | ||
6) | TCBOD is the treatment cost incurred by the Authority as updated annually per 1,000 pounds of BOD. | ||
7) | TCSS is the treatment cost incurred by the Authority as updated annually per 1,000 pounds of suspended solids. | ||
8) | TCDS is the treatment cost incurred by the Authority as updated annually per 1,000 pounds of dissolved solids. | ||
9) | TCNH3N is the treatment cost incurred by the Authority as updated annually per 1,000 pounds of ammonia nitrogen. | ||
