Town of Bennett Agenda Item 27a <br /> November 19-20, 2014 Board Meeting(Updated November 21, 2014) <br /> Page 3 of 5 <br /> Annual <br /> Well Permit No. Aquifer Appropriation <br /> (AF/yr) <br /> South System <br /> 9 60555-F _ Laramie- Fox Hills 109 <br /> 10 53691-F Laramie - Fox Hills 109 <br /> 11 54164-F Arapahoe 184 <br /> 13 64350-F Arapahoe 184 <br /> 14 58829-F Arapahoe 184 <br /> a) Combined annual appropriation of wells#3 and 8 not to exceed 207 AF/yr <br /> b) Combined annual appropriation of wells#4,5,6 and 7 not to exceed 190 AF/yr <br /> c) Dually completed in both aquifers <br /> Project Description <br /> The goal of this Project is to re-drill wells #3 and #6 so the Town can continue providing reliable water <br /> to its residents. <br /> Alternative 1 - Do Nothing: This alternative was considered unacceptable. Without wells #3 and #6 <br /> the Town's water system lacks the desired redundancy to provide water service to its residents in the <br /> event that additional wells fail. <br /> Alternative 2 - Rehabilitate Wells: Based on video evaluations of wells #3 and #6, it was determined <br /> that the wells have deteriorated beyond repair. <br /> Selected Alternative 3 - Drill Replacement Wells: Given the need for both wells to service the <br /> Town's water a demand and the poor condition of the existing wells, replacing both wells was selected <br /> as the preferred alternative. <br /> Well #3 will be drilled into the Laramie-Fox Hills Aquifer within 300-feet of the existing well. It is <br /> expected to be a 10-inch well, drilled 1,570 feet deep. <br /> Because dually completed wells are no longer allowed by the Division of Water Resources, Well #6 will <br /> be replaced with two wells (one in the Denver aquifer and one in the Upper Arapahoe aquifer). Both <br /> wells will be located within 100 feet of the existing well. The Arapahoe aquifer well is expected to be <br /> a 10-inch well, drilled 740 feet deep. The Denver aquifer well will be 8-inches and 445 feet deep. <br /> TABLE 2: Construction Cost <br /> Task Cost <br /> Consulting Fees $114,562 <br /> Drilling/Permitting $1,090,838 <br /> Pump $394,600 <br /> Total $1,600,000 <br /> Permitting: Permits are required from the Colorado Division of Water Resources. Well approval from <br /> the Water Quality Control Division will also be required prior to using the new wells. <br /> Schedule: The Town intends to drill both well #3 and #6 in the spring of 2015. Drilling is expected to <br /> take three months. <br /> Financial Analysis <br /> The Town qualifies the current middle-income municipal interest rate of 3.25% for a 30-year term. <br /> Table 3 provides a summary of the Project's financial aspects. <br />
