<br />potential of the new housing stocl< is 18.9 gpcd (32%). If similar savings are available in the <br />multi-family sector (a reasonable assumption based on research on multi-family indoor demands <br />such as the 2004 National Submetering Study) then the current overall indoor conservation <br />potential in Aurora can be estimated at 5,800 AF3 if full plumbing fixture replacement was <br />achieved. <br /> <br />Table 6: Average single-family residential demand, Aurora Water <br /> Total Use <br /> 05-06 AWe Indoor Outdoor Avg.Day AvglndoorDay <br /> (kgal/yr) (kgal/month) (kgal/yr) (kgal/yr) (gpd) (g pd) <br /> Pre-2001 Homes <br />Mean 134.2 5.3 63.7 70.5 367.0 174.3 <br />Std Dev. 61.7 3.1 37.6 51.3 168.5 102.8 <br /> Post-2001 Homes <br />Mean 138.5 4.7 56.4 82.1 379.1 154.4 <br />Std Dev. 58.4 2.4 29.0 48.5 159.9 79.3 <br /> <br />Water Costs and Pricing <br /> <br />Billing system and Rates <br />Aurora Water has used a form of inclining block rate structures since July of 2002. Prior to that <br />from1999 through 2001, a uniform rate of $1.91 per 1,000 gallons was used and in early 2002, a <br />uniform rate of $2.04 per 1,000 gallons was adopted. In July of 2002, a three tier blocl< rate was <br />implemented. From 2003-2006 a water budget inclining block rate structure was in place. Aurora <br />Water uses a monthly billing cycle. <br /> <br />Currently, Aurora Water uses a 4-block inclining block rate structure for every single family <br />detached home/ townhome water account, based on individualized winter quarter averages <br />(WQA). Blocl< 1 represents the WQA, Block 2 is the next 15,000/4,000 gallons, Blocl< 3 is the <br />next 10,000/3,000 gallons and anything above that amount resides in Block 4. See Table 7 for <br />detailed information on the rate structure as it pertains to other types of water accounts. <br /> <br />3 Assumes 45% of residential demand is indoors and an overall conservation potential of 38% of indoor use. <br /> <br />9 <br />
