<br />..escribe the amount, of estimated Water savings. For projects that, consen/e Water, please state
<br />the estimated amount Of Water expected to be conserved (in acre-.: 'e,et per, year) as a direct
<br />result of this project. Describe the .,iijpp()r1,1(1(')cijment-at'i(')n of estimated Water savings.
<br />This Project will save 101.4 acre feet per year (AFY) of water based on reduced water use for
<br />energy production. According to researchers at the Virginia Water Resources Research Center,
<br />in Blacksburg, Virginia; fossil -fuel -fired thermoelectric power plants consume more than 132
<br />billion gallons of fresh water per day (2008) in the United States alone, which translates to an
<br />average of 25 gallons of water to produce 1 kilowatt-hour (kWh) of electricity. II„I ,I ,I , p ..,, ,.,prv,!

<br />The City currently purchases energy from SCE which receives energy from a variety of sources.
<br />The main energy generation facilities for SCE are located in SCE's service area of Southern
<br />California. Although the City does not provide water directly to SCE power generation facilities,
<br />SCE's power generation facilities are located Southern California, which is a region currently
<br />experiencing severe impacts to its water supplies due to the ongoing drought. The City cannot
<br />guarantee that the Project will result in water savings in City's service area; however, water
<br />savings will occur since the Project is shifting the Garthe and West Pump Stations from fossil
<br />fuel fired thermoelectric power to solar power, which requires no water in the electricity
<br />generation process.

<br />Currently 101.4 AFY of treated water is being used to produce the energy needed to power the
<br />Garthe and West Pump Stations. Implementation of the proposed Project could help recover
<br />the drinking water currently being used for energy production that could be used for other
<br />needs.
