<br />Other Accounts - This category is for those a small group of commercial <br />water users that are outside of the City limits. This category will not grow in <br />the future. <br /> <br />4. Does the City qualify as a covered entity? Yes <br /> <br />5. Background Information <br />a. Per capita water use in the City varies over the last five years, depending <br />on the calculation method and the year, as indicated in Table 1. Per <br />capita residential water use was calculated based on total residential <br />water use and the end of the year population for the City. Per capita total <br />water use was calculated based on total retail water use and the end of <br />the year population. <br />b. Past and current population served is provided in Table 1. Future <br />population growth is expected to continue at roughly a 3 percent increase <br />per annum, based on recent past growth. <br />c. Water savings goals to be achieved through the Plan implementation are <br />expected to be developed base on segment of water use. For example, <br />residential water use will trend downward over time as older residences <br />are retrofitted with new and more water efficient appliances. New home <br />lot sizes are also trending downward, with an expected result of reducing <br />outdoor watering needs per capita. The biggest water savings that the <br />City will realize over the next planning period related to water <br />conservation plan implementation, is expected to be related to <br />commercial and irrigation accounts. These accounts grew by 12 and 41 <br />percent, respectively, from 2004 to 2005, and therefore, water <br />conservation measures and programs identified and selected in the 2007 <br />Water Conservation Plan to be developed and implemented by the City <br />will likely ~us on improving water use efficiency in these two water use <br />segments. Based on c rent and future water use, the City expects that <br />water cons'ervatio goal to be developed during planning, will be in the <br />range of 1 to 1.5% pe ear occurring over th~ ~t 15 to 20 years, which <br />will be a long term savings of 15 to 30 per~ <br />d. The City' s w~s-un er of sources. First, <br />the City has a!,uild-out population project of 96,000. metime within <br />the next 8 to 20 years, e cur filter water <br />treatment plants will come to capacity, requiring the construction of new <br />and/ or expanded facilities. Second, RO generates a brine waste that is <br />costly to dispose. Although the City currently operates effective and <br />efficient water supply facilities, future community needs will overwhelm <br />the existing facilities output. Water conservation will play an important <br />role in reducing demand, and thereby saving augmentation, groundwater <br />production, and water treatment costs in the future. Noteworthy is that <br />, the City is a member of both the Metro and South Platte River Round <br />Tables, since the City is situated in both geographies in Adams County. <br />The City shares in the water supply gap that is identified for the South <br /> <br />5 <br />
