treatnlent plant is used and useful in providing service to all customers receiving treated water <br />service, the saine does not hold true for all of the heated water distribution system. Campbell <br />Soup and Direct Energy currently receive treated water directly from ground storage via <br />transmission lines, not directly from the City's distribution lines. LCWSD receives the bulk of <br />their water purchases at the City's water treatment plant or through the City's transmission lines. <br />In the aUsence of detailed distrilxrtion system analysis during peak hour flow conditions, the <br />treated water transmission and distribution lines have been segregated by inch-feet into three <br />groups - lines less than 8 inches in diameter, lines between 8 inches and 24 inches in diameter, <br />and lines greater than 24 inches in diamctcr - for cost allocation purposes between the classes of <br />treated water customers. Table A-2 in Appendix A shows the percentages of inch-feet of treated <br />water transmission and distriUution lines separated into the three pipe size groups. <br />D. Treated Water Loss Allocation <br />No treated watcr loss has been prorated to water received Uy Campbell Soup, Direct Energy, and <br />LCWSD «ater consumption contrachially categorized as "plant water" due to the location of <br />their point of talce fi-om the City's transmission system. TaUle A-3 in Appendix A shows treated <br />water a(location percentages to the City's retail customers, Campbell Soup, LCWSD and Direct <br />Energy, including treated water losses allocated to the retail customers of the City and LCWSD <br />watee consumption tal<cn thi•ough the City's disti•ibution system. <br />F. Treated Water Use and Cauacitv Requirements of Customer Classes <br />To distribute fiinctionalized system component costs to customer classes - Residential class, <br />Commercial class, CampUell Soup, LCWSD and Direct Energy, assumptions had to be niade as <br />to peak-day demands of Residential and Commercial classes of customers since peak-day <br />metered demands are not available for the Residential and Commercial classes. Campbell <br />Soup's, Direct Energy's, LCWSD's average day and peak day demands were based on actual <br />metered data for FY 2009. Tablc A-1 in Appendix A shows the individual customer classes' <br />average and peak-day demands. The table also shows the capacity factors for the classes as well <br />as their relative percentages of base and extra capacity components of the system used and useful <br />in providing setvice to the five custoiner classes during the test year. <br />9 Cim of Pnris, Tesns <br />If'ater nnd Wnstewnter Cosi of Service Sturl>> <br />June ?010 <br />234 <br />
