WATER CONSERVATION PLAN 2008 <br />The City has four treatment plant facilities and is currently in the process of <br />decommissioning its oldest treatment plant, the South Treatment Plant, which is <br />currently not in operation. One additional plant, the North Treatment Plant, is <br />currently not operated. Two water treatment plants remain in operation: the Wade <br />Gaddis Filtration Plant and the newly constructed Nelson - Flanders Water Treatment <br />Plant (WTP). The Wade Gaddis plant has a capacity of 20 million gallons per day <br />(mgd) and operates seasonally. The Nelson - Flanders WTP was commissioned in <br />2006 and has a capacity of 30 mgd, giving the City a current treatment plant capacity <br />of 50 mgd for the Nelson Flanders and Wade Gaddis water treatment plants. The <br />Nelson Flanders plant has been built to be expandable to 60 mgd to accommodate <br />the City's anticipated water demands at build out, resulting in a total treatment <br />capacity of 80 mgd. Drinking water is distributed to the City through 88 miles of <br />transmission lines and 344 miles of distributions mains which contain <br />approximately 3,638 hydrants. <br />In addition to its potable water distribution the City has an extensive network of <br />canals and irrigation ditches that convey raw water to parks, golf courses, schools, <br />and greenways for irrigation. Currently raw water is available to irrigate <br />approximately 27 city and community parks, two golf courses, and thirteen schools, <br />which represents 50 percent of parks, 66 percent of golf courses, and 72 percent of <br />school grounds. The site of the City's main recreation facility is also irrigated with <br />raw water. Availability of raw water for irrigation decreases demand for treated <br />water from the treatment plant and conserves energy and chemicals required for <br />treatment. <br />TABLE 2 <br />Summary of Water Supply Sources <br />Annual Water Supply Annual Volume (AF) Percent Metered <br />Total Raw Water Used <br />201332 - <br />Non- Potable Used' <br />11452 0% <br />Treated Water Production <br />197881 100% <br />Total Annual Water Sold <br />157460 100% <br />1 Estimated based on 30 inches of raw water applied to 580 irrigated acres of parks, golf courses, <br />greenways, and schools. There are 387 acres irrigated by raw water, and approximately 389 <br />acres that may be irrigated with either raw or treated water. The 580 acres represents all of the <br />irrigated acres with raw water plus 50 percent of the irrigated acres with both raw and treated <br />water. <br />2 Total treated water production plus water lost during treatment plant operations is 5.3% based <br />on 2002 to 2007 data. <br />3 City does not get billed for treated water used (see Table 3). <br />
