City of Pleasanton <br />2025 Water Rate Study <br /> <br />Water Resources Economics <br />56 <br />3.5 EQUIVALENT METER UNITS <br />Costs related to meter capacity increase based on meter size. Therefore, equivalent meter units are <br />calculated to provide a basis from which to allocate costs in proportion to meter size. Equivalent meter <br />calculations are shown in Table 3-9. <br /> <br />Equivalent meters are calculated based on meter capacity ratios, which represent the safe operating <br />capacity of a water meter relative to the base meter size. For this study, the base meter size is a 5/8” <br />meter, which is the most common meter size in the City’s system. Capacity in gallons per minute (gpm) is <br />derived from the AWWA M1 Manual. The meter ratio for a 1 1/2” meter is 5.00, which means that the <br />capacity of a 1 1/2” meter is five times that of a 5/8” meter. <br /> <br />The number of meters in each meter size is from Table 2-6 and Table 2-7. Equivalent meters are <br />calculated by multiplying the meter counts by the meter ratio in each size. <br /> <br />Table 3-9: Equivalent Meter Units <br />Line Meter Size Safe Operating <br />Capacity (gpm) Meter Ratio Number of <br />Meters <br />Equivalent <br />Meters <br />1 5/8" 20 1.00 15,356 15,356 <br />2 3/4" 30 1.50 4,867 7,301 <br />3 1" 50 2.50 3,527 8,817 <br />4 1 1/2" 100 5.00 643 3,216 <br />5 2" 160 8.00 527 4,216 <br />6 3" 350 17.50 84 1,470 <br />7 4" 630 31.50 20 630 <br />8 6" 1,300 65.00 7 455 <br />9 8" 2,800 140.00 3 420 <br />10 10" 4,200 210.00 0 0 <br />11 Total 25,034 41,880 <br /> <br /> <br /> <br />
