2019 Water, Recycled Water, and Sewer Rate Study <br />3. Cost -of -Service Analysis <br />Table 3-10: Total Sewer Rate Revenue Requirement Calculation Summary <br />Total Costs $7,434,954 $504,244 $7,939,197 <br />Non -Rate Revenue ($1,443,194) ($1,443,194) <br />Revenue Requirement $5,991,759 $504,244 $6,496,003 <br />3.1.4 Step 4: Distribute Costs to Customer Classes <br />Finally, rate revenue requirements are then distributed to customer classes based on the customer class <br />units of service characteristics with regard to each Cost Group. The units of service are measured in <br />terms of number of accounts, water usage (for water only), and equivalent meters (which are explained <br />below). <br />A meter equivalency schedule is an industry -standard factor used to represent the relative capacity <br />associated with different types and sizes of meters. A meter equivalency schedule allows for indexing of <br />each meter size in terms of multiples of the lowest common denominator (in this case a 5/8" x 3/4" meter). <br />The existing meter equivalency schedule, that is inferred from the Water Enterprise's current Basic Water <br />Service Charge, is not recognized by the Stantec team as a published or calculated equivalency <br />schedule. This Study recommends that it be replaced with a standard meter equivalency table from <br />AWWA's M22 manual as shown in Table 3-11. <br />Table 3-11: Proposed Meter Equivalency Schedule <br />3/4" <br />Turbine Class 1 <br />30 <br />1.50 <br />1" <br />Turbine Class 1 <br />50 <br />2.50 <br />1 1/2" <br />Turbine Class 1 <br />100 <br />5.00 <br />2" <br />Turbine Class 1 <br />160 <br />8.00 <br />3" <br />Turbine Class 1 <br />350 <br />17.50 <br />4" <br />Turbine Class 1 <br />630 <br />31.50 <br />6" <br />Turbine Class 1 <br />1,300 <br />65.00 <br />8" <br />Turbine Class 2 <br />2,400 <br />120.00 <br />10" <br />Turbine Class 2 <br />3,800 <br />190.00 <br />(a) Source: Table 6-1 AW WA meter Standards, AWWA M22 Manual, 2nd Ed <br />Therefore, a single 5/8" x 3/4" meter is equal to one equivalent meter (EM), while an 8" meters is equal to <br />120 EMS. <br />City of Santa Ana Stantec 123 <br />
