<br />somewhat conservative because it assumes that current system losses will increase <br />with increasing demands and reflects the situation that would occur without any <br />additional conservation measures. If future conservation measures or system leak <br />repairs are implemented, there will be more water available to Paonia than described in <br />our analysis. <br /> <br />A 30-year planning period was used in our evaluation at the request of the <br />CWCS staff to be consistent with the period of the CWCS loan. As a result, the 184 <br />million gallons (565 acre-feet) of treated water outflow volume was applied to the year <br />2000 and subsequent future demands were projected to 2032 to reflect demands at the <br />end of the 30-year CWCB loan that was originally expected to be approved in the year <br />2002. The result of this analysis is summarized in Table 6 and graphically in Figure 10. <br /> <br />TABLE 6 <br />SUMMARY OF PROJECTED FUTURE WATER DEMANDS <br />(million gallons) <br />l-percent 1.5-percent <br />Growth Growth <br />184.0 184.0 <br />193.5 198.2 <br />203.3 213,5 <br />213.6 230.0 <br />224.5 247.8 <br />236.0 267.0 <br />248.0 287.6 <br />253.0 296.3 <br /> <br />Year <br />2000 <br />2005 <br />2010 <br />2015 <br />2020 <br />2025 <br />2030 <br />2032 <br /> <br />System Yield <br /> <br />2-percent <br />Growth <br />184.0 <br />203,2 <br />224,3 <br />247.6 <br />273.4 <br />307.9 <br />333.3 <br />346.8 <br /> <br />The firm yield of Paonia's water collection system is the amount of water that <br />the system is expected to deliver during two consecutive dry years. The approach for <br />estimating firm yield used in the Draft 2000 Study was to correlate treatment plant <br />inflow records with average monthly stream flow data. This approach was used <br />because of the lack of other reliable data and does not include data from the 2002 <br />drought. WestWater Engineering performed a regression analysis of the average <br />monthly stream flow data at the Somerset gage on the North Fork of the Gunnison <br />River and inflow records of both the 1 MG and 2 MG treatment plants. Inflow records <br />were available for the 1 MG treatment plant from 1995 through 1999 and for the 2 MG <br /> <br />20 <br />
