Are there any known benefits associated with where the current losses are going? For <br />example, is seepage water providing additional habitat for fish or animal species? <br />There are currently no known benefits associated with current losses due to leaks in the City <br />water system. <br />d. Describe the support/documentation of estimated water savings. Please provide sufficient <br />detail supporting how the estimate was determined, including all supporting calculations. <br />According to researchers at the Virginia Water Resources Research Center, in Blacksburg, <br />Virginia; fossil -fuel -fired thermoelectric power plants consume more than 132 billion gallons of <br />fresh water per day (2008) in the United States alone, which translates to an average of 25 <br />gallons of water to produce 1 kilowatt-hour (kWh) of electricity. IEEE Spectrum, by Willie Jones, <br />April 1, 2008. <br />D.2. Evaluation Criterion B—Renewable Energy <br />D.2.1. Subcriterion No. B.1: Implementing Renewable Energy Projects Related to Water <br />Management and Delivery <br />Describe the amount of energy capacity. For projects that implement renewable energy <br />systems, state the estimated amount of capacity (in kilowatts) of the system. Please provide <br />sufficient detail supporting the stated estimate, including all calculations in support of the <br />estimate. <br />In February 2019, the City approved a "Water Systems Alternative Energy Feasibility Study" <br />prepared by Newcomb Anderson McCormick (NAM), a Willdan Company ("NAM Study"). This <br />study included an evaluation of the potential to install on -site renewable energy systems to <br />offset some of the electrical load, lower electric bills, and reduce the associated greenhouse gas <br />(GHG) emissions. The renewable energy resources that were evaluated included installing solar <br />PV modules on the roofs of the storage tanks at five of the pump stations, including Garthe and <br />West. This study is posted in Appendix B. <br />The results of the NAM Study determined that the estimated annual amount of energy that <br />would be generated would be 894,325 kWh at the Garth site and 422,617 kWh for the West <br />site, for a total of 1,316,942 kWh annually. Given that there are 8,760 total hours in a year, a <br />simple calculation reveals that this equates to a capacity of approximately 150 kW per year. <br />Describe the amount of energy generated. For projects that implement renewable energy <br />systems, state the estimated amount of energy that the system will generate (in kilowatt hours <br />per year).
