<br />The projected 2025 average load is determined as follows: <br /> <br />Projected 2025 BOD = (0.185 x 297,585 x 1.3) + 2,402 = 74,000 mgd (actual calculated value of <br />73,9711001 day roUnded to the nearest hundred pounds) <br /> <br />Where: <br /> <br />0.185 is the selected pounds per capita per day (Ppcd) based on dry season <br />values from 1990 to 2002 .. . <br /> <br />- 297,5851s the p~ojected population to be served in: 2025. <br /> <br />1.3 is the selected peaking to convert average dry season load to D5MM load <br />(based on 1990 to 2002 data) <br /> <br />2,402 is the projected industrial flow in lbsj day (it has been assumed that the <br />industrial load will remain constant over the study period) <br /> <br />The required capacity to meet the needs of growth in terms of BOD is 19,200 lbsj day <br />. (74,000 - 54,8(0). <br /> <br />TSS <br /> <br />The methodology for TSS is identical to that of BOD. The existing capacity, although not <br />explicitly stated in the current NPDES permit, is 71,600 lbsj day, which was the value used <br />for the origirial WPCF design. The current loading orcurren~!,equired, presented in D5MM <br />terms, is 64,700lbsj day and is determined as follows: <br /> <br />Current 1'55 = (0.205 x217,737 x 1.4) + 2,224 = 64,700 lbsj day (actual calculated value of <br />64,715 lbs j day rounded to the nearest hundred pounds) . <br /> <br />Where: <br /> <br />0.205 is the selected pounds per capita per day (Ppcd) based on dry season <br />values from 1990 to 2002 <br /> <br />217,737is the population served in 2002 <br /> <br />1.4 is the selected peaking to convert average dry season flow to' maximum <br />month dry season flow (based on 1990 to 2002 data) <br /> <br />2,224 is the current industrial TSSloadin lbsjday <br /> <br />The available capacity in terms of 1'55 is 6,900 lbsj day (71,600 - 64,700). <br /> <br />The projected 2025 average TSS is determined as follows: <br /> <br />Projected 2025TSS= (0.205 * 297,585* 1.4) + 2,224 = 87,600 mgd (actual calculated value of <br />87,6311bsj day) rounded to the nearest hundred pounds) <br /> <br />Where: <br /> <br />0.205 is the selected pounds per capita per day (ppcd) based on dry season <br />values from 1990 to 2002 <br /> <br />297,585 is the projected population to be served in 2025 <br /> <br />A-30 <br />
