<br />1. Based on City of Rifle staff projection that 250 EQRs will be added annually through 2012 and 300
<br />EQRs per year thereafter
<br />2.Based on an average of 2.33 capita per EQR added; 2.33 is average of ratios of non-CoGen EQRs to
<br />total population for 2005, 2006, and 2007.
<br />3. Based on average of approximately 400 gpolEQR of average finished water production required per
<br />EQR historically times the historical average multiplier of 2.56 for peak day to average day water
<br />production, yielding 1,024 gpolEQR.
