acre-feet and in 2005 171 acre-feet of the total 221-acre feet available in Wells <br />No. 2, 4, 5, 7 and 8. In the Water Supply Evaluation Report, it was determined <br />that 483.4 acre feet of water would be needed in 2030. This means that the <br />Town needs to develop infrastructure to deliver an additional 262.4 acre-feet of <br />water to its customers. The two wells at the Roggen site are decreed to have <br />247 acre-feet. These wells will nearly supply the water for the Town's needs for <br />the next 20 years. However, the Roggen wells would need to be pumped <br />approximately 10 miles into Town to be used in the future. This option will be <br />further described under Alternative 2A herein. <br />It should also be recognized that the Roggen wells will not improve the water <br />quality and their use should only be considered once an acceptable blending <br />percentage is achieved utilizing the Lost Creek water or utilizing the appropriate <br />treatment technology to remove fluoride and sodium. At this time, it does not <br />appear that the Roggen wells will need to be used until after 2030 or if the Town <br />wells need to be supplemented to improve reliability of the system. <br />If the Town were going to implement an exact 50-50 blend, a total of 242 acre- <br />feet of Laramie-Fox Hill and Lost Creek water would be required given the <br />projected total flow needed of 483.4 acre-feet. The Town will be able to obtain <br />an additional 21 acre-feet of Laramie-Fox Hill water as new land is annexed into <br />Town due to the requirement that the developer dedicate their water shares to <br />the Town as part of the development process. In the event that the Town is not <br />able to acquire the total 242 acre-feet of Lost Creek water, it could accommodate <br />the 50-50 blending and meet the projected needs for the next 5 years by only <br />obtaining as little as 110 acre-feet. Therefore the amount of Lost Creek water <br />that will need to be acquired over the next 20 years is in the range of 110 to 242 <br />acre-feet. <br />A summary of the required waster assuming a 50-50 blend is shown in the table <br />below: <br /> <br />Year <br />Water <br />Required <br />Laramie Fox Hill <br />Water <br />PV Water Required <br />PV Water <br /> Projected Available Projected Available <br /> Ac-Ft Ac-Ft Ac-Ft Ac-Ft Ac-Ft Ac-Ft <br />2010 220.6 110.3 221 110.3 139.6 0 <br />2015 268.4 134.2 221 134.2 139.6 0 <br />2020 326.6 163.3 221 163.3 (1) 23.7 <br />2025 397.3 198.7 221 198.7 (1) 59.1 <br />2030 483.4 241.7 221 241.7 (1) 102.1 <br />Note: (1) Additional PV Water purchase will be required. <br />Feasibility Study - Keenesburg, CO <br />1/23/2009 5 <br />
