<br />REVISED DRAFT <br /> <br />1lI. <br /> <br />ANALYSIS OF TEST YEAR DATA <br /> <br />A. <br /> <br />Water Utility System Data <br /> <br />The City maintains daily treated water production data at the treatment plant. The system peak <br /> <br />pumpage of treated :vater recorded on July 25, 2001 was 20.428 million gallons with a peak to <br /> <br />average day ratio of 1.66 (20.428 MGD/ 12.322 MGD). Table A-I in Appendix A shows the <br /> <br />system demand and capacity factors for the test year. <br /> <br />B. <br /> <br />Allocation Operation and Maintenance Expenses to Functional Cost Components <br /> <br />In order to recognize that certain facilities of the City's water utility system are used in common <br /> <br />by two, three, four or all five of the customer classes identified in Section II, five customer <br /> <br />groups have been formed for system cost allocation purposes. These cost factors have also been <br /> <br />separated into three principal components of Base, Extra Capacity, and Customer costs to <br /> <br />provide a means of further distributing functionalized costs to the various customer classes on <br /> <br />the basis of the respective responsibilities of each group for each particular cost function. <br /> <br />Each element of cost is allocated to functional cost components of the system on the basis of the <br /> <br />parameter or parameters having the most significant influence on the magnitude of the element <br /> <br />of cost. <br /> <br />Operation and maintenance expenses are allocated directly to appropriate cost <br /> <br />components. Similarly, debt service costs are allocated to the appropriate cost functions. <br /> <br />CityolParis, Te,as <br />Water and Wastewater Cost olService Study <br />March 2003 <br /> <br />11 <br />
