(A) Purpose. All industrial users shall pay that portion of all federal grant amounts expended upon the city’s sewerage treatment works subsequent to 3-1-1973, allocable to the treatment of their sewerage wastes, based upon the following formula set forth in division (B) of this section.
(B) Industrial cost recovery formula. Industrial cost recovery amounts based on each industrial contributor’s flow, BOD and SS, as compared to the design load of flow, BOD and SS. Each industrial contributor would then pay the federal grant amount allocated to each flow, BOD and SS according to the contributor’s percent of the design land, such as:
a — percent federal grant — flow = $475,303.95
b — percent federal grant — BOD = $136,898.03
c — percent federal grant — SS = $136,898.03
d — design flow = 0.650 MGD
e — design BOD load = 1105 lbs. per day
f — design SS load = 1430 lbs. per day
g — useful life = 30 years
(1) Amount contributed for flow:
a = cost/year/gallon = $24,374.56/MGD/year
d × g
(2) Amount contributed for BOD:
b = cost/year/lb. BOD = $4.13/lbs/day/year
e × g
(3) Amount contributed for SS:
c = cost/year/lb. SS = $3.19/lbs/day/year
f × g
