§ 53.24 SURCHARGE FOR BOD5 AND SS.
   (A)   Rates. The rates of surcharges for BOD5 and SS shall be as follows:
   CS = [Bc(b) + SC(S)] Vu
(1989 Code, § 3.40, Subd. 7E)
   (B)   Computation of surcharge. The concentration of wastes used for computing surcharges shall be established by waste sampling. Waste sampling shall be performed as often as may be deemed necessary by the city, or its representative, and shall be binding as a basis for surcharges.
(1989 Code, § 3.40, Subd. 7F) (Ord. 33, 2nd Ser., eff. 5-21-1999)
§ 53.25 COMPUTATION OF WASTEWATER SERVICE CHARGE.
   The wastewater service charge shall be computed by the following formula:
   CW = CDS + CM + (Vu - X) CU + CS
Where:
CW
=
Amount of wastewater service charge ($) per billing period
CDS
=
Debt service charge
CM
=
Minimum charge for operation, maintenance and replacement
Vu
=
Wastewater volume for the billing period
X
=
Allowable consumption in gallons for the minimum charge
Cu
=
Basic user rate for operation, maintenance and replacement
CS
=
Amount of surcharge
Bc
=
$0.141/lb. BOD 5
B
=
BOD - 100 mg/l
S
=
SS - 250 mg/l
