<br />Projected City Water Supply
<br />Table 5.142 shows the City of Santa Ana's supply and demand for normal conditions for the years 2015
<br />through 2035. Additional water supplies are projected to be available but are not included in this table
<br />because projected supplies meet projected demands.
<br />Table 5.14 -2 Projected Normal Year Water Supply and Demand for the City of Santa Ana (ACY)
<br />ACY = Acre4eet/year
<br />Soumz: City d Santa Ana, 2011.2010 Urban Water Management Plan.
<br />The City has determined that it is 100 percent reliable for single dry year demands from 2015 to 2035 with a
<br />demand increase of 7.2 percent, using FY 2003 -2004 as the single dry year. The available imported supply is
<br />greater than shown on Table 5.143, but is not included because all demands are met.

<br />The City is also capable of providing their customers with the water demand with significant reserves in
<br />multiple dry years from 2015 to 2035, with a demand increase of 7.2 percent using FY 2003 -2004 as the
<br />multiple dry years. This is true even if the demand projections were to increase by a large margin. The
<br />projected multiple dry year period supply and demand numbers for the first, second and thud year supply are
<br />the same as those provided in Table 7 for a single dry year (2010UWAV).
<br />Water Storage and Distribution
<br />Santa Ana has approximately 444 miles of transmission and distribution mains, 8 storage reservoirs totaling
<br />49.3 million gallons capacity, including its one million gallon elevated storage tank, and 20 city owned
<br />groundwater wells. There are seven MWD connections in the city that can supply a combined total of 56,250
<br />gallons per minute (gpm) into the city's main distribution system. Water system pipe sizes within the project
<br />area are shown on Figure 5.14 -1, Existing lhater System Poe Sides.
