<br />CDIVI <br /> <br />Town of Erie Water Conservation Plan Grant Amendment <br />March 2007 <br /> <br />2.0 Proj ected Demands <br /> <br />The projected demands provided in the original grant application were developed for <br />treated water master planning purposes and do not take into account historical per <br />capita water usage. After further evaluating potential conservation water savings, it <br />was determined that the original projected demands do not provide a firm baseline <br />for comparison of future demands with conservation water savings. <br /> <br />Projected demands have been modified to reflect the pre 2002 drought per capita <br />water usage, shown in Figure 3. A per capita water usage of 216 gpcd (the per capita <br />water usage for 2002) was used to develop the projected demands. This per capita <br />usage was multiplied by the anticipated annual population estimates provided in the <br />original grant application. These projected demands will serve as the baseline when <br />evaluating future conservation water savings. <br /> <br /> 9,000 <br /> 8,000 <br />52 7,000 <br />LL <br />~ <br />en 6,000 <br />"'0 <br />C <br />co <br />E 5,000 <br />Q) <br />0 <br />"'0 <br />Q) 4,000 <br />U <br />Q) <br />.0' <br />So.... 3,000 <br />0... <br />co <br />(5 2,000 <br />I- <br /> 1,000 <br /> 0 <br /> <br /> <br />I'- 00 <br />o 0 <br />o 0 <br />N N <br /> <br />""'" LO <br /> <br />o 0 <br />N N <br /> <br />'"" N ('f) <br />N N N <br />o 0 0 <br />N N N <br /> <br />""'" LO <br />N N <br />o 0 <br />N N <br /> <br />(J) 0 '"" <br />o '"" <br />o 0 0 <br />N N N <br /> <br />N ('f) <br />o 0 <br />N N <br /> <br />CD I'- 00 <br />o 0 0 <br />N N N <br /> <br />(J) 0 <br />N <br />o 0 <br />N N <br /> <br />Figure 3: Modified Projected Demands <br /> <br />3.0 Estimated Water Savings Goals <br />The following goals will be an important component of the Water Conservation Plan. <br /> <br />1. Target an annual per capita water usage of 170 gpcd by 2014. The per capita <br />water usage will be calculated using the population projections provided in the <br />grant application and annual metered water usage (for potable and raw water <br />usage). This annual per capita water usage provides a water savings of 1/110 AFY <br />(21 percent) when compared to the projected demands provided in Figure 3. <br /> <br />3 <br /> <br />\\DENSVR01\PROJECTS\9228 - ERIE\CONSERVATION PLAN\GRANT APPLlCATION\WATER CONSERVATION AMENDMENT FINALDOC <br />
