<br />TOWN OF CASTLE ROCK <br />"Teach By Example" Program Summary <br />Page 11 <br /> <br />homeowners however averaged 97 gcd, even with establishment consumption for their new <br />exterior landscapes. This translates into an overall savings of 22.4%. <br /> <br />If every residential account achieved this level of water savings, the Town could <br />realize a saving of 308 acre feet per year, which relates to $78,905 in water production <br />costs, and $80,331 in wastewater treatment costs. These figures also can be related to <br />enough water to serve 560.5 single family equivalents, which equals 1,569 people, for a <br />year. <br /> <br />This could also be translated into delaying the requirements to build new water <br />treatment plants, or drill new wells to service existing populations, or expand wastewater <br />treatment facilities. <br /> <br />Alternately, decreasing water sales by over 100,400,000 gallons of water would <br />negatively impact revenues by between $100,400 - $150,600, barely recouped by the <br />production and wastewater treatment costs. However, the benefits are realized dramatically <br />on the supply development side of the water production!consumption equation. <br /> <br />Achieving the production of 308 AF/yr would require the investment of over <br />$300,000, not including distribution or treatment infrastructural costs that would accompany <br />such water service development. These figures were based on acquisition of Denver basin <br />aquifer water as noted in the Town's Water Resource Management Plan. <br /> <br />INCENTIVE CREDIT PROGRAM <br /> <br />This program showed us what works in Castle Rock. it gave an outline on what we <br />should base our incentive credit program rebates. <br /> <br />Exterior retrofit is a complicated endeavor, and should be considered for <br />reimbursement by committee on a case by case basis. The retrofit should at least alter half <br />of an existing landscape, and therefore not just consist of replacement of a particular plant. <br /> <br />Interior devices are a more straight forward reimbursement item and should be <br />considered by their savings/cost ratio. Shower heads consistently offer high return, and <br />averaged over 100% of their cost. Therefore, rebates should reflect this. <br /> <br />UL V's reflected an average savings/cost ratio of 16%. And front loading washers <br />reflected a consistent 11 % return. <br /> <br />t... <br /> <br />The estimated number of customers that will take part in the Incentive Credit Program <br />should be based on the number of homes over five years old, the cost of item replacement, <br />and a participation factor consistent with similar programs along the front range. A specific <br />payable account will be set up to accurately track out going credit funds, and keep the <br />account on budget. The efficiency of the Incentive Credit Program should be monitored, <br />including the amount of advertisement to notify customers that the credit funds are <br />
