0City of Santa Ana Recycled Water Master Plan <br />Assessment of Potential Recycled Water <br />Customers <br />The second step in completing the recycled <br />water master plan <br />is to develop potential <br />recycled water <br />demands. Proper <br />TRHA will focus on <br />Identification of potential <br />developing a list of <br />recycled water demands <br />users with a high <br />is the basis of <br />likelihood of using <br />developing a recycled <br />recycled water. This <br />water system. The <br />will be based on the <br />success of recycled <br />type and quantity of <br />water systems is based <br />water use, and similar <br />on identification and <br />past successful <br />verification of real <br />recycled water <br />customers that have a <br />conversions in <br />willingness to use <br />Southern California. <br />recycled water. <br />The TRHA Team <br />understands that the <br />potential recycled water customers within <br />the City are likely to be categorized into the <br />following three categories; the approaches <br />to convert each of these customers are <br />different: <br />1, Landscape Irrigation, such as <br />schools, parks, golf courses, street <br />medians, and multi -family irrigation; <br />2. Industrial/Commercial Process <br />Water, such as cooling towers and <br />water used in producing product <br />such as concrete, carpet washing, <br />chemical milling; and <br />3. Agricultural, <br />TRHA's approach will be to first develop a <br />recycled water customer database, <br />identifying potential recycled water <br />customers with demands greater than two <br />acre-feet/year. The database will include not <br />only the location and demand of customers, <br />but also the use of the water and specific <br />water quality requirements for each of the <br />potential customers. <br />The primary source of information will come <br />from the City's existing potable water billing <br />database, focusing on the top potable water <br />customers, with customers geocoded to the <br />location of the service connection. We will <br />estimate the potential recycled water usage <br />based on existing potable water demands of <br />customers and our experience regarding the <br />percentage of potable water demands that <br />can be successfully converted to recycled <br />water. <br />The City can free up potable demand by <br />converting additional major irrigation <br />customers. The City currently has 35 parks, <br />4 joint use sites, and 19 recreational <br />facilities, of which only 6 are currently being <br />irrigated with recycled water. The TRHA <br />Team has extensive experience in working <br />with the parks and recreation departments <br />of multiple cities, and working with school <br />staff and boards for elementary, middle, <br />high school, and junior colleges, our <br />understanding of how they do business, <br />their challenges, and they administrative <br />procedures are key ingredients in obtaining <br />a commitment from these users. <br />Another potential cycled water use consists <br />of converting industrial/commercial users <br />from potable water to recycled water. The <br />primary industrial/commercial uses would <br />be industrial cooling both in the <br />manufacturing process and for cooling <br />towers. There may also be industrial users <br />which could use recycled water for <br />producing products such as concrete, <br />carpet cleaning. <br />Firm Team, Understanding of Need and Approach, and Scope of Work <br />25A-18 <br />Page 5 <br />
