.. .\ ..J.J e..' 1994 Master Plan Update Town of Elizabeth As shown, additional supply must be added to the water system to meet the current demands and the projected demands on the system. The storage capacity is slightly lower than criteTia for the pTojected demands, but is acceptable thTOUgh the study peTiod if the supply is gTeater than peak day demand. Table 5 shows that 70 gpm must be added to meet the current demands and 175 gpm must be added to meet the minimum supply requirements for the projected demands through the study period. Water System Recommendations We recommend that, at a minimum, the total additional supply of 175 gpm be added to the system immediately by constructing and equipping a new well to the Arapahoe aquifer. The well should be sized to allow the pumping rate to be increased to the maximum aquifer yield in the future. The Town should consider equipping the well to the full capacity of the aquifer (approximately 300 gpm). This will allow the other wells to be rested and used only on a stand-by or backup basis. The additional cost to equip the well to full capacity is expected to be small relative to the total well facility cost. This alternative can be evaluated once the well is drilled and the capacity is determined. We have not reviewed the total annual yield of water to determine if it is currently available from the existing wells. We have also assumed that the additional flow rate and annual yield necessary to meet the demands projected through the study period will be available from one well in one aquifer. These assumptions must be confiTmed by Mr. Robert Tafelski, HRS Water Consultants, the Town's groundwater consultant. WateT System Costs Estimated costs for the recommended improvements to the supply and storage facilities are summarized in Table 6 below. Meurer & Associates October 5, 1994 Page 9
