§ 51.070 COMPUTATION OF SURCHARGE.

   (A)   The surcharge per user shall be computed by the following formula:

         S - V(0.00834) [A(BOD-204) + B(SS-240)]

   Where:   S = Amount of Surcharge ($)

   V = Wastewater Volume in 1,000 gallons per billing period

   (0.008340) = Unit weight of water x 10-6 per 1,000 gallon

   A = Unit charge for BODS per lb., $0.13

   BODS - five-day biochemical oxygen demand, mg/l (no less than 204 mg/l)

   204 = Allowable BODS strength

   B = Unit charge for SS per lb., $0.10

   SS = Total Suspended Solids, mg/l (no less than 240 mg/l)

   240 = Allowable SS, mg/l

   (B)   The concentration of wastes discharged in excess of normal strength wastes shall be used for computing surcharges and shall be established by sewage flow metering and waste sampling. Waste sampling and testing by an approved laboratory shall be completed by the discharger as often as may be deemed necessary by the Manager and shall be binding as a basis for surcharge.
