All five wells have been developed in the Franconia -Ironton -Galesville (FIG) aquifer. A <br />more complete description of the subsurface stratigraphy and geologic morphology is <br />provided in Item 19. Figure 19.3 graphically displays the well drilling logs for the three <br />wells on and adjacent to the RTC site. <br />Table 13.3 summarizes the capacity of each well and its permitted appropriation. <br />Table 13.3: Well Capacities and Permitted Appropriations <br />DNR <br />Permit <br />Well Number <br />Unique <br />Well <br />Number <br />Permitted Permitted Pump <br />Flow Withdraw- Capacity <br />(gpm) al (MGY) (gpm) <br />No. 1 856005-1 161441 4,900 970 <br />No.2 856005-2 416183 4,900 220 <br />No. 3 856005-3 580303 4,900 1,450 <br />No. 4 856005-4 580313 4,900 855 <br />No. 5 856005-5 593672 4,900 900 <br />Total 500(2) 4,395 <br />(1) Assumes 20-hour pumping day for 365-days and does not allow for recharge or resting of the <br />aquifer. <br />(2) Current DNR Permit allows a combined annual appropriation of 500 MGY. <br />Maximum <br />Annual <br />Capacity <br />(MGY)WWW <br />424.860 <br />96.360 <br />635.100 <br />374.490 <br />394.200 <br />1,925.010 <br />Water Storage. Storage and distribution pressure for the municipal water system is <br />provided by two elevated storage tanks with capacities of 0.5 and 1.5 million gallons <br />respectively. The 1999 Water System Study demonstrated the need for the construction of <br />additional elevated storage to meet future demands on the water system. This <br />recommendation was based on an analysis of existing and projected future flows and <br />included factors such as fire flow capacity, emergency storage, daily peak use, and water <br />supply and pumping capacity. <br />Table 13.4 lists the existing water storage facilities as well as those projected in the 1999 <br />Water System Study for future construction. The location of these facilities is indicated in <br />Figure 13.3. <br />Table 13.4: Existing and Future Water Storage Facilities <br />Description <br />Reservoir No. 1 <br />Reservoir No. 2 <br />Reservoir No. 3 <br />Usable Storage <br />Volume (gal) <br />500,000 <br />1,500,000 <br />1,000,000 <br />Year <br />Constructed <br />1989 <br />2000 <br />Projected 2009 <br />High Water <br />Elevation <br />1036 <br />±1035 <br />N/A <br />13-3 <br />
