<br />. <br /> <br />c <br />. <br /> <br />. <br /> <br />It has been documented that the "average" single family customer applies less than the <br />ET, and that in order to achieve savings from an ET based irrigation control system it is <br />therefore necessary to concentrate on the top quartile of single family water users. <br />Typical application rates in multi family site tend to be higher because there the inigation <br />is managed by a contractor who doesn't pay the water bills. So, the top two quartiles will <br />be used to select target lists for the multi family sector. <br /> <br />The participating water utility will be asked to extract customer infoffilation from the two <br />target groups. From these lists mailings will be sent out, on Utility letterhead, inviting <br />participation in the project. NCWCD may also provide a cover letter giving its <br />endorsement of the project. Since there will be no cost to any customer during the first <br />year, we anticipate a good degree of success in attracting potential participants, but we <br />still believe that 10 invitations need to be mailed out for each desired participant. <br />Therefore, a total of 200 participation letters will be mailed out by the utility to random <br />sets taken from the single family and multi-family target groups. <br /> <br />e <br /> <br />While participation from the residential sector will be the main goal of the solicitation, <br />participants from commercial and public sectors will be investigated on a case by case <br />basis. Office building, retail spaces, street medians and parks are all potential <br />participants. Attempts to solicit sites from these sectors will be made in consultation with <br />the utility; based on their knowledge of which sites might make good candidates and <br />examination ofbiIIing records. <br /> <br />In order to have the system in place at the start of the 2000 inigation season it will be <br />important to mail the invitations as early as possible; hopefully they can be mailed by the <br />middle of February or earlier. <br /> <br />Task 2: Collect Responses and Screen Applicants <br /> <br />Each letter will provide a phone number the customer can call to ask questions or request <br />a more detailed evaluation. A return post card will also be provided so that the customer <br />can mail back a response. Customers requesting more information will be sent a detailed <br />description of the ET Signal Controller system and how it will be used in this <br />demonstration project to assess its ability to limit inigation to desired targets, and <br />consequently save water. <br /> <br />e <br /> <br />All phone and mail responses will be directed to Aquacraft where they will be tabulated <br />and screened. Those individual who indicate a willingness to participate will be <br />contracted to determine if their sites are acceptable. The analysis will include a <br />determination of the number and types of irrigation clocks present on the site and the <br />number of zones in the system. The total inigated area will be determined either from <br />mapping or field measurements. The historic water use records will be used to estimate <br />the typical outdoor use and inigation applications at each site. Sites meeting the project <br /> <br />5 <br />
