Table 3-6: System-Wide Peaking Factors <br /> System Peaking Factors Peaking Factor Base Max Day Max Hour I <br /> 1 Base 1.00 100% 0% 0% 100% <br /> 2 Max Day 1.40 71% 29% 0% 100% <br /> 3 Max Hour 2.50 40% 16% 44% 100% <br /> 4 Average Max Day/Max Hour 56% 22% 22% 100% <br /> Table 3-7 shows the customer class-specific peaking factors based on the maximum bi-monthly usage divided by <br /> average bi-monthly usage for each class and tier. This peaking factor is used as a proxy for the class and tier- <br /> specific Max Day peaking factors(Column B), which are based on the current tiers. The Max Hour peaking factor <br /> is calculated based on the relative factor from the system-wide peaking factors. <br /> For example, the Residential class Max Hour peaking factor(Column C, Line 1) is calculated as follows: <br /> Residential Max Day Peaking Factor[Bl]x(System-wide Max Hour peaking factor[Table 3-6,B3]/System-side Max Day <br /> peaking factor[Table 3-6,B2])=Residential Max Hour peaking factor[CI] <br /> Table 3-7: Class-Specific Peaking Factors <br /> PeakingLine Customer Clas�, Max Day Max Hour <br /> Factor Peakin,�Factor <br /> 1 Single Family Residential 1.71 3.05 <br /> 2 Tier 1 1.22 2.18 <br /> 3 Tier 2 1.98 3.53 <br /> 4 Tier 3 2.42 4.32 <br /> 5 Tier 4 2.62 4.68 <br /> 6 Multi-Family Residential 1.19 2.13 <br /> 7 Commercial/Industrial 1.30 2.33 <br /> 8 Irrigation 1.99 3.55 <br /> 9 Recycled Water Irrigation 2.17 3.87 <br /> 3.6. Peak Capacity <br /> Table 3-8 shows the calculation of additional capacity required to meet Max Day and Max Hour demands. The <br /> Max Day(Column D) and Max Hour(Column G) were derived in the previous subsection (Table 3-7) for each <br /> customer class and tier. <br /> Annual use(Column B) is derived from the water usage projections(Table 2-6)based on the current tiers. Note <br /> that the total annual use for each class(Column B, Lines 1, 6-10) are equal to the total water use for each class in <br /> the projections. Annual use is then converted to average daily use(Column C), assuming 365 days in a year. <br /> The Max Day capacity in ccf per day(Column E)is calculated by multiplying the average daily use(Column C)by <br /> the Max Day peaking factors(Column D). The Max Day extra capacity in ccf per day(Column F) is equal to the <br /> Max Day capacity(Column E) less average daily use (Column C). <br /> 38 CITY OF PLEASANTON <br />
