Based on these data, it appears that the City's customers responded to the drought <br />by cutting back on water use by about 25%. This reduction is likely due to a <br />combination of mandatory watering restrictions, regional messaging (i.e., television <br />and newspaper articles on the drought) and local messaging. <br />Since the drought in 2002/2003 when water use was at its lowest, total per capita <br />water use (including both treated water and raw water as shown in Table 4) has <br />climbed about 30 % . However, the 2006 total per capita use is about 10 % below that <br />measured in 2000, and total per capita water use in 2007 is about 5 % less than that <br />measured in 2000. <br />The observed increase in total per capita water use is strongly correlated to <br />increased commercial and irrigation water use including municipal parks water use <br />(related to new parks being constructed), since these combined accounts have <br />increased by 85 % over the past 4 years. <br />On the other hand, per capita "residential only" water use (based on column 2 in <br />Table 4) for the City has ranged from about b8 gpcd in 2003 to 81 gpcd in 2006 (see <br />Table 4, column 14), representing a 19 % increase over this time period; however per <br />capita residential demand did not grow from 2006 to 2007: it remained at about 80 <br />gpcd). <br />Overall, it is estimated that the past water use, represented by those years prior to <br />mandatory watering restrictions (i.e.,1998 to 2001) has been reduced by about 5% <br />based on total per capita water use in comparison to the water use in the past f our <br />years (i.e., 2004 to 2007). The observed reduction in total per capita water use is <br />assumed to be a result of the City's past water conservation efforts including <br />customer education, residential indoor appliance rebates, outdoor watering <br />restrictions, inclining block rate water rates and the City's leak detection program. <br />Future water conservation measures and programs will continue to address all the <br />different water uses by the City's customers to reduce overall water use such that <br />the specific goals presented in Section 6 can be achieved. <br />City of Brighton Water Conservation Plan 8 <br />
