As summarized above in Table 13, if the residential and multifamily per capita water use <br />decreases from the average of 103 gpcd to 90 gpcd for new construction there is a slight <br />decrease in the treated water demand, which decreases from 3,574,000 to 3,531,000 <br />thousands of gallons, approximately 1.2 percent. This is also illustrated in Figure 4 below. <br />3,750,000 <br />3,500,000 <br />3,250,000 <br />3,000,000 <br />C <br />2,750,000 <br />a� <br />°0 275007000 <br />0 <br />r <br />2,250,000 <br />2,000,000 <br />17750,000 <br />1,500,000 <br />Residential and Multifamily Metered Usage <br />Gaps indicate incomplete data for that year. <br />Residential cusotmers <br />not fully metered until <br />end of 2006. <br />�, Total Res +Multi Usage <br />Total Res +Multi Usage (adjusted for unmetered) <br />—o-- Residential & Multifamily Forecast (90 gpcd) <br />—S-0� Residential & Multifamily Forecast (103 gpcd) <br />CD I- M M O � N M"t LO 0 I� M M O � N M� LO 0 I� M M O M"t LO 0 I� M M O <br />M M M M M M M M M M M M M M 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 <br />N N N N N N N N N N N N N N N N N N N N N <br />Year <br />FIGURE 4 <br />Residential and Multifamily Metered Usage <br />5.2 Peak Monthly and Daily Treated Water Demands <br />Forecasted demands presented in the subsection represent total treated annual water <br />demand projections. However, it is important and useful to also predict the daily peak <br />and total monthly water demand as a means to evaluate the potential need for water <br />demand management to reduce peak demand on infrastructure such as water treatment <br />capacity. To this point, forecasted daily peak water demands may be compared to current <br />system capacity for treatment and distribution and identify any critical capital needs the <br />system faces. <br />The following is a brief summary of the methodology used to predict daily peak water <br />demands: <br />30 <br />
