ACOMPREHENSIVE SANITARY <br />SEWER PLAN <br />2040 COMPREHENSIVE PLAN UPDATE DRAFT Dec14-17 <br />for review only <br />Wastewater Flow Projections <br />Wastewater flow projections were generated for each sanitary Sewer <br />District within the 2040 MUSA and corresponding sub-districts <br />based on the gross developable acreage available, anticipated land <br />uses, and wastewater flow generation rates. The wastewater flow <br />generation rates for the various land uses found Table 10-8 were <br />used to project the future wastewater flows for the service area. <br />Wastewater flow projections for the eastern portions of the City outside <br />of the 2040 MUSA were calculated on an average wastewater flow <br />generation rate per gross acre of 900 gallons per day average as <br />land use and population projections for this portion of the City are not <br />available� <br />The MCES Peak Flow Design Factors are summarized in Table 10- <br />3. Estimated peak hour flows are not totaled as the peaking factor is <br />dependent upon the average day flow rate. Summing the projected <br />peak hour flow rates would produce a flow rate higher than the peak <br />hour flow rate for the entire City. Therefore, the following existing, <br />2040 MUSA, and ultimate peak hour flows were calculated by <br />multiplying the total average flows by the appropriate MCES peaking <br />factor� Table 10-9 below presents the existing, projected 2040, and <br />projected ultimate flows for each sanitary Sewer District. <br />Table 11-9 2040 Wastewater Flows per Sewer District <br />Sanitary Sewer <br />District <br />Existing Average <br />Day Flow (MGD) <br />Existing Peak <br />Hour Flow <br />(MGD) <br />2040 Average <br />Day Projected <br />Flow (MGD) <br />2040 Peak Hour <br />Projected Flow <br />(MGD) <br />Ultimate <br />Average Day <br />Projected Flow <br />(MGD) <br />Ultimate Peak <br />Hour Projected <br />Flow (MGD) <br />A 0�0008 0�0033 0�209 0�794 0�209 0�794 <br />B 0�0016 0�0062 0�002 0�006 0�002 0�006 <br />C 0�0053 0�0213 0�005 0�021 0�005 0�021 <br />D 0�0083 0�0331 0�026 0�103 0�026 0�103 <br />E 0�0514 0�2058 0�183 0�714 0�183 0�714 <br />F 0�0058 0�0230 0�006 0�023 0�006 0�023 <br />G 0�0202 0�0806 0�040 0�160 0�040 0�160 <br />H 0�0102 0�0408 0�016 0�065 0�016 0�065 <br />I 0�0913 0�3653 0�215 0�817 0�215 0�817 <br />J 0�0655 0�2620 0�140 0�545 0�140 0�545 <br />K 0�1500 0�5849 0�409 1�430 0�409 1�430 <br />L 0�0309 0�1236 0�056 0�223 0�056 0�223 <br />M 0�0433 0�1731 0�091 0�362 0�091 0�362 <br />N 0�1325 0�5167 0�338 1�218 0�338 1�218 <br />O 0�590 2�008 0�590 2�008 <br />P 0�405 1�418 0�405 1�418 <br />Q 1�017 3�152 1�017 3�152 <br />R 0�170 0�662 0�170 0�662 <br />S 0�116 0�454 0�116 0�454 <br />T 1�71 4�96 <br />U 3�79 9�48 <br />V 5�90 13�57 <br />Total System 0617 2098 403 1008 1543 2932 <br />Note: Existing, projected 2040, and projected ultimate peak hour flows equal the total average flow multiplied by peaking factors per MCES� The sum of the existing peak hour flow does not <br />equal the sum of the peak discharges from each district since the peaking factor decreases as the average flow increases� Peaking factors were taken from MCES factors included in Table <br />10-3�
