46 <br />WATER RATE STUDY I City of Santa Ana, CA <br />Table -17: Allocation of Net Capital Costs in Thousands of Dollars to Functional Cost Components <br />Units of Service <br />The total cost responsibility of each class of service may be established by developing unit costs of <br />service for each cost function and assigning those costs to the customer classes based on the respective <br />service requirements of each. To properly recognize the cost of service, each customer class is allocated <br />its share of base, maximum day and peak hour costs. The number of units of service required by each <br />customer class provides a means for the proportionate distribution of costs previously allocated to <br />respective cost categories. Summarized in Table 18 are the estimated units of service for the various <br />customer classes. <br />M LI � • <br />NOVEMBER 2014 <br />Source of Supply <br />1 <br />(Source of Supply) <br />22,321.2 <br />22,321.2 <br />0.0 <br />0.0 <br />0.0 <br />0.0 <br />0.0 <br />0.0 <br />Pumping Plant <br />2 <br />(Pumping Plant) <br />384.2 <br />192.2 <br />96.0 <br />96.0 <br />0.0 <br />0.0 <br />0.0 <br />0.0 <br />Treatment <br />3 <br />(Treatment) <br />5,496.0 <br />3,664.0 <br />1,832.0 <br />0.0 <br />0.0 <br />0.0 <br />0.0 <br />0.0 <br />Transmission & <br />Distribution <br />4 <br />(T &D) <br />29,312.0 <br />15,359.5 <br />11,724.8 <br />2,227.7 <br />0.0 <br />0.0 - <br />0.0 <br />0.0 <br />Meters & <br />Services <br />5 <br />(Meters) <br />1,099.2 <br />(0.0) <br />0.0 <br />0.0 <br />1,099.2 <br />0.0 <br />0.0 <br />0.0 <br />Hydrants <br />6 <br />(Hydrants) <br />732.8 <br />(0.0) <br />0.0 <br />0.0 <br />0.0 <br />0.0 <br />732.8 <br />0.0 <br />General Plant <br />7 <br />(Admin) <br />983.2 <br />368.8 <br />98.3 <br />98.3 <br />196.6 <br />196.6 <br />24.6 <br />52.1 <br />8 <br />Total <br />$60,328.5 <br />$41,905.6 <br />$13,751.1 <br />$2,422.0 <br />$1,295.8 <br />$196.6 <br />$757.4 <br />$52.1 <br />Less Other Revenue <br />9 <br />Misc.
