<br />A. Average Daily Flow:
<br />Cost of Component + Design flow = Cost per gallon of average daily flow
<br />($23,371,902/49,000,000) + ($405,000/2,000,000) gal per day = $0.680 per gal of average daily flow
<br />
<br />B. Peak Flow * (allocates peak wet weather capacity to average user flow):
<br />Cost of Peak Flow Component + Average Design flow = Cost of peak flow capacity per gallon of
<br />average daily flow
<br />($45,681,445/49,000) + ($34,090,000/88,000,000) gal per day = $1.320 per gal of average daily flow
<br />
<br />C. Biochemical Oxygen Demand (BOD):
<br />Cost of BOD Component + Design BOD daily capacity = Cost per pound of BOD per day
<br />($20,,184,824/66,000) + ($1,297,048/2,167) pounds per day = $904.38 per pound
<br />
<br />o. Suspended Solids (55):
<br />Cost of SS Component + Design SS daily capacity = Cost per pound of SS per day
<br />($16,997,747/71,600) + $1,297,048/2,167) pounds per day = $835.95 per pound
<br />
<br />* The reimbursement unit cost of Peak Flow is calculated on the basis of average daily plant capacity of 49,000,000 to enable
<br />recovery of costs from system users. Flow estimation units are expressed in average daily flow.
