Unit Costs of Capacity <br />As illustrated in Table 1, a central factor in the SDC fee calculation is the system-wide unit cost <br />of capacity, for each of the four capacity parameters (lines 2, 4, and 6 of Table 1). Tables 2 and 3 <br />below show the calculation of system-wide reimbursement and improvement unit costs by <br />capacity parameter. The system-wide unit costs are calculated by dividing the total projected <br />costs of providing capacity for new development (Growth Costs) by the total projected amount <br />of capacity required by new development (Growth Units). The reimbursement unit costs <br />(indicated in bold in Table 2) are used on line 2 of Table 1. <br /> <br /> Table 2 <br /> Reimbursement Unit Cost Calculations <br /> Component Amount <br /> Growth Costs <br /> Average Flow $1,204,444 <br /> Peak Flow $0 <br /> BOD $2,293,819 <br /> TSS $1,403,456 <br /> Total $4,901,719 <br /> Projected Growth Units <br /> Average Flow (mgd) <br /> 15.5 <br /> Peak Flow (mgd) 30 <br /> BOD (lbs) 19,200 <br /> TSS (lbs) 22,900 <br /> Cost per Unit <br /> Average Flow ($/gpd) $0.78 <br /> Peak Flow ($/gpd) $0.00 <br /> BOD (S/lb) $119.47 <br /> TSS (S/lb) $61.29 <br /> Combined BOD/TSS (S/lb) $180.76 <br /> <br /> Table 3 I [ I <br /> [m?rovement Unit Cost Calculations <br /> Component Amount W/Financing* <br /> Growth Costs <br /> Average Flow $14,260,171 <br /> Peak Flow $12,654,487 <br /> BOD $15,653,765 <br /> TSS $15,243,603 <br /> Total $57,812,027 <br /> Projected Growth Units <br /> Average Flow (mgd) 15.5 <br /> Peak Flow (mgd) 30 <br /> BOD (lbs) 19,200 <br /> TSS (lbs) 22,900 <br /> Cost per Unit <br /> Average Flow ($/gpd) $0.92 $1.02 <br /> Peak Flow (S/gpd) $0.42 $0.47 <br /> BOD (S/lb) $815 $902 <br /> TSS (S/lb) $666 $737 <br /> Combined BOD/TSS (S/lb) $1,480.96 $1,639.29 <br /> *Financing cost adjustment: I 10.7% <br /> <br /> <br />
