<br />CDM <br /> <br />Section 5 <br />Conservation Goals <br /> <br />conservation efforts. Goals 1 through 3 target quantitative water savings goals, while <br />Goals 4 and 5 focus on Erie's selection of conservation measures/ programs and <br />implementation of these measures/programs. Section 9 provides more information. <br /> <br />Figure 5-1 conceptually illustrates the quantitative water conservation savings targets <br />for Goals 1 and 3, respectively. The total targeted water savings of 1,350 AFY by the <br />2014 (Goal 1) includes both demand management and reclaimed water use. For <br />purposes of this Plan, the use of recycled (reclaimed) water is a second-time use and is <br />considered conserved water. Through the use of reclaimed water, Erie offsets the need <br />for additional first use water, decreasing overall water needs. As shown in Figure 5-1, <br />demand management savings are targeted to provide 610 AFY of water savings <br />whereas reclaimed water use is targeted to save approximately 740 AFY. <br /> <br /> 7,000 <br /> 6,500 <br /> 6,000 <br />:> 5,500 <br />LL <br />~ <br />(I) 5,000 <br />"'C <br />s:::: <br />(tIi <br />E 4,500 <br />Q) <br />0 <br /> 4,000 <br /> 3,500 <br /> 3,000 <br /> 2007 <br /> <br /> <br />Saving s from <br />r1er:p~ Mgmt <br /> <br />Saving s from <br />Re claim ed <br />Water Use <br />740 MY <br /> <br />;.I-p- -~b\e-Water-Demand <br />Rawanu Old <br /> <br />2008 <br /> <br />2009 <br /> <br />2010 <br /> <br />2011 <br /> <br />2012 <br /> <br />2013 <br /> <br />2014 <br /> <br />- Tdal Projected Demands (Pdable, Raw, & Reclaimed Water) <br />- Tdal Projected Demands (Pdable, Raw, & Reclaimed Water) with Demand Management <br />-Potable and Raw Water Demands <br /> <br />Figure 5-1 Projected Water Demands with and without Conservation <br />(Assuming Goal 1 targeted savings) <br /> <br />The total targeted savings of 1,350 AFY (equivalent to 221 gpcd) specified in Goal 1 <br />was developed by evaluating the historical per capita water usage for potable and <br />raw water shown in Figure 5-24. (As discussed above, reclaimed water usage is not <br />included in per capita demands because for purposes of this Plan, reclaimed water is <br />considered conserved water). A per capita water usage of 221 gpcd was chosen as the <br />targeted per capita demand for 2014 following reclaimed water use and demand <br />management. This per capita demand is higher than the majority of historical per <br />capita demands shown in Figure 5-2. <br /> <br />4 The 221 gpcd includes use of raw/lease water as well as billed and unbilled potable water. <br />As discussed in Section 3, the per capita water usage of billed potable water would be <br />significantly less. <br /> <br />DRAFT <br /> <br />5-2 <br /> <br />\\DENSVR1\PROJECTS\9228 - ERIE\CONSERVATION PLAN\REPORT\DRAFT PRIOR TO PUBLIC REVIEW\CONNIE FORMATTED\SECTION 5.DOC <br />
