SURVEY BACKGROUND <br />The graphic below depicts the change in the average cost of water <br />and wastewater service to residential users over the past 10 years. <br />• The blue and green bars represent the average residential charge for <br />6,000 gallons of water and wastewater, respectively, each year based <br />`~"",~„'~"",~„~, ~"" . on data provided by survey respondents in that year. "1'he orange <br />a_._..,-.- - line illustrates the Consumer Price Index for all urban consumers <br />..lam (CP1-U) each year. The CPi-U price statistic is a general indication <br />of inflation or deflation, measured as the average change in the price <br />of consumer items-goods and services that people buy for day-to- <br />day living. <br />A comparison between the blue and green bars to the CPI-U (orange <br />line) gives an indication of how the average cost of water and <br />wastewater utility service, respectively, has changed since 2002 <br />as compared to ane measurement of inflation/deflation. These <br />changes could be a reflection of a number of things, such as capital <br />improvements driven by regulatory mandates, efforts to catch up <br />on deferred capital investment, capital investment and rate increase <br />initiatives to address water supply issues related to drought, and <br />efforts to implement sustainability measures such as full-cost pricing. <br />• <br />h <br />a <br />t9 <br />0 <br />0 <br />O <br />,o <br />O <br />it <br />i~ <br />O <br />d <br />Q <br />h <br />0 <br />0 <br />of <br />a <br />L <br />W <br />a <br />• <br />AVERAGE MONTHLY RESIDENTIAL WATER AND WASTEWATER CHARGE FOR 6,000 <br />GALLONS WATER/WASTEWATER FROM 2002-2011 <br />METRO AND NON-METRO SURVEY RESPONDENTS <br />$30.00 <br />$25.00 -} <br />$20.00 ~~ <br />$15.00 <br />$10.00 <br />$5.00 <br />$- <br /> <br />J <br />,~ <br />F <br />} <br />• - -- _ _ - <br />Lopyught ~~ 201 I AE2S dll Rights Reter~ed 201 I hlorth (en~rnl Utility Rnte $m ae•/ {Page 5 <br />
