Average day flows were calculated by determining <br />the acreages of each land use designation in each district, assuming a <br />typical flow generated per capita, and scaling the flows to coincide with <br />MCES flow data. <br />All trunk sanitary sewer mains exhibited adequate capacity for the <br />existing system flows. Table 11-4 summarizes the existing average <br />and peak system flows by Sewer Sub-District. The flows reported <br />below do not include flow from upstream Sub-Districts. However, <br />cumulative flows from upstream Sub-Districts were considered in the <br />capacity analysis of existing trunk sewer and lift stations� <br />As detailed in the following table, all of the City’s existing lift stations <br />have sufficient capacity to accommodate additional growth. Table <br />10-5 shows existing lift station pump capacity and existing peak flow <br />information� <br />Sewer Sub- <br />District <br />Adjusted <br />Average Flow <br />(MGD) <br />MCES <br />Design Peak <br />Flow Factor <br />Design Peak <br />Flow (MGD) <br />J3 0�0053 4�0 0�0213 <br />J4 0�0125 4�0 0�0500 <br />J5 0�0204 4�0 0�0817 <br />K1 0�0715 4�0 0�2860 <br />K2 0�0249 4�0 0�0996 <br />K3 0�0074 4�0 0�0295 <br />K4 0�0301 4�0 0�1204 <br />K5 0�0161 4�0 0�0643 <br />L1 0�0134 4�0 0�0534 <br />L2 0�0104 4�0 0�0416 <br />L3 0�0071 4�0 0�0286 <br />M1 0�0433 4�0 0�1731 <br />N2 0�0184 4�0 0�0735 <br />N3 0�0083 4�0 0�0331 <br />N4 0�0389 4�0 0�1554 <br />N5 0�0194 4�0 0�0777 <br />N6 0�0225 4�0 0�0902 <br />N9 0�0250 4�0 0�1001 <br />Total Existing <br />System Flows <br />0617 34 2098
