<br />ARAPAHOE COUNTY WATER AND WASTEWATER AUTHORITY <br /> <br />1.2 SOURCES OF WATER <br /> <br />ACWW A currently has 17 wells that are used for water supply. Seven of the wells pump from <br />the Cherry Creel( Alluvium and the remaining ten wells pump from deeper confined aquifers <br />within the Denver Basin. These aquifers are the Arapahoe, Denver, Dawson, and Laramie Fox <br />Hills (LFH) Aquifers. Table 1-3 summarizes the capacities and sources of the ACWWA wells. <br /> <br />Table 1-3: Current ACWWA Well Sources and Capacities <br /> <br />Well Name Aquifer Capacity Age of Conditions of Use <br /> (gpm) Improvements <br />A-I Arapahoe 500 4 Y2 Years None - Used year-round <br />A-2 Arapahoe 300 4 Years None <br />Airport 3 Arapahoe 275 2 Years None <br />Braun Alluvial 1,200 3 Years Summer Season Only <br />Denmarl( Arapahoe 350 6 Years None <br />Arapahoe <br /> <br />Denmarl( <br />Dawson <br /> <br />Dawson <br /> <br />50 <br /> <br />N/A <br /> <br />N/A <br /> <br />Denmarl( LFH LFH 200 6 Years Summer Season Only <br />Ford 2 Alluvial 1,200 1 Year None <br />LFH5 LFH 120 U sed for Augmentation <br />Loyd Alluvial Alluvial 1,250 2 Years None <br />(2) <br />Loyd Dawson 80 6 Years None <br />(Antonoff) <br />Dawson <br />Loyd (No 1) LFH 80-125 7 Years None <br />LFH <br />Loyd Denver Denver 80-120 7 Years None <br />Race 1 Alluvial 900 5 Years None <br />Race 4 Alluvial 1,200 1 Year Irrigation Only <br />Smith 1 Alluvial 1,200 3 Years Irrigation Only <br /> <br />Smith 2 <br /> <br />Alluvial <br /> <br />1,150 <br /> <br />3 Years <br /> <br />Summer Season Only <br /> <br />Because water quality in some of the aquifers is better than others, usage priority generally is as <br />follows: the Arapahoe Aquifer, the Cherry Creel( tributary alluvial aquifer, the Dawson and <br />Denver Aquifers, and finally the Laramie Fox Hills Aquifer. These aquifers are described in <br />more detail below. Currently the well water is disinfected at the well head with sodium <br />hypochlorite and then pumped directly into the distribution system. An oxidation sequestering <br />agent is also administered at some of the wells to control the precipitation of iron in the well <br />water. <br /> <br />Richard P.
