water demand factor is approximately 15.2 mgd. The existing firm supply capacity is approximately 17.2 mgd, which results in a supply surplus of 2.0 mgd.

7.5.2

Future Supply Requirements

Future supply requirements, in 5-year increments, were identified for the City and are also summarized on Table 7.1 . As shown on Table 7.1 the City’s existing firm supply capacity is sufficient to meet the City’s future supply requirement until the year 2030, at which point the supply requirement exceeds the City’s existing firm supply capacity and a new well is required to be constructed. Following the construction of this new well the City will not need to construct a new well to meet the future supply requirement until the year 2030, when the future supply requirement will exceed the City’s future firm supply capacity. The proposed groundwater wells are described as follows:

 BR-W1: Construct a new 800 gpm groundwater well on Burnett Avenue. This facility will be located approximately 6,000 feet northeast of Monterey Avenue.

 NH-W1: Construct a new 800 gpm groundwater well on Butterfield Avenue. This facility will be located approximately 400 feet northeast of the intersection of Railroad Avenue and Fisher Avenue.

7.6 WATER STORAGE REQUIREMENTS

The City’s existing domestic water system storage capacity is identified in this section. Additionally, this section identifies the existing and future storage requirements to meet the storage capacity and compares it with the existing storage facilities in each zone and makes recommendations for new storage facilities.

7.6.1

Existing Storage Requirements

Existing storage requirements were identified for each pressure zone and are summarized in Table 7.2 . The table lists the existing domestic water demands and identifies the operation, fire, and emergency storage for each pressure zone. This table also lists the total required storage for existing domestic water demands at 8.7 MG.

7.6.2

Future Storage Requirements

Future storage requirements were identified based on the buildout of the 2035 General Plan and summarized by pressure zone on Table 7.3 . The table lists the future domestic water demands and identifies the operations, fire, and emergency storage for each pressure zones. The table also lists the total required storage for future domestic water demands at 6.0 MG.
