The methodology showing the calculation of the total sewer service charge shall be as set forth herein:
USER CHARGE RATE FOR NORMAL DOMESTIC SEWAGE
C
u
= Unit Cost ($/1,000 gal)
C
t
= Total OM&R Cost($)
F
t
= Total Flow (gallons)
C
u
= C
t
/ (F
t
/ 1,000 gal)
Sample Calculation:
C
t
= $500,000 (Total OM&R Cost)
F
t
= 200,000,000 gal (Total Flow)
C
u
= $500,000 / 200,000,000 gal / 1,000 gal)
C
u
= $2.50 / 1,000 gal
SURCHARGE RATES FOR TREATMENT PARAMETERS
P
u
= Unit Cost to Treat Parameter ($/ lbs.)
P
t
= Total Cost to Treat Parameter ($)
P
w
= Total Weight of Parameter Treated (lbs.)
P
u
= P
t
/ P
w
Sample Calculation:
P
t
= $48,000 (Total Cost to Treat Parameter)
P
w
= 600,000 lbs. (Total Weight of Parameter Treated)
P
u
= $48,000 / 600,000 lbs.
P
u
= $0.08 / lbs.
P
u
= Cost per pound surcharge levied per pound over the limits for normal domestic wastewater as stated in Section 1054.01(a)(32).
DEBT SERVICE CHARGE
D
a
= Annual Debt Payment
F
t
= Total Flow (gallons)
D
u
= Debt Service Charge Unit Cost ($ / 1,000 gal)
D
u
= D
a
/ (F
t
/ 1,000)
Sample Calculation:
D
a
= $700,000 (Annual Debt Payment)
F
t
= 200,000,000 gal (Total Flow)
D
u
= Debt Service Charge Unit Cost ($ / 1,000 gal)
D
u
= $700,000 / (200,000,000 gal / 1,000)
D
u
= $3.50 / 1,000 gal
