<br />CONI <br /> <br />Castle Pines North Metropolitan District <br />Application for Water Efficiency Grant <br /> <br />Generally, demands have increased as the number of homes has increased. Total <br />demands in 2002 and 2003 were relatively high, while in 2004 the demand noticeably <br />decreased. This is likely attributable to customers' response to regional drought <br />awareness campaigns, the District's efforts to encourage conservation, and an <br />abnormally wet year in 2004, which reduced the need for irrigation. Demands have <br />increased since 2004. This may indicate that customers are returning to pre-drought <br />water use practices, typical of a drought memory effect. <br /> <br />Per Capita Annual Water Demands <br /> <br />Estimates of per capita water demands (gallons per capita per day, or gpcd) are <br />shown in Figure 2. As shown in the equation below, per capita demands for the <br />service area were estimated by dividing potable system water demands (i.e., total well <br />production minus water used by the Ridge Golf Course) by the total population. Total <br />potable water demands include irrigation of District-owned property and irrigation of <br />homeowner association (HOA) properties, The total population includes employment <br />in the school and commercial sector, residents, and an estimated amount of additional <br />people/traffic using the District's commercial services (restaurants, car washes, etc.). <br /> <br />Total annual well production - (Annual golf course water use) <br />Per capita demands <br />Total popu lation x 365 days <br /> <br /> 250 <br /> 211 204 <br />.-... 200 195 189 <br />-c 178 <br />0 <br />c. 160 <br />..g! 157 <br />Ul 151 <br />-c 150 140 <br />c: <br />111 <br />E .. <br />Ql <br />0 lIT ,~ 1\ <br />~ 100 <br />'0.. <br />(II <br />U III <br />.... <br />Ql <br />0- 50 {l <br /> IIIl <br /> ~ i'NJ <br /> 0 <br /> 1998 1999 2000 2001 2002 2003 2004 2005 2006 <br /> <br /> <br />Figure 2 <br />Daily Per Capita Water Demands for District Service Area (excluding Ridge Golf Course water use) <br /> <br />3 <br /> <br />C'COCUMENTS ANe SETTINGS',BLACKCA\cESKTOPICPNGRANTlWATER EFFICIENCY GRANT PROGRAM APPLICATtON.OOC <br />
