City of Morgan Hill
Water System Master Plan
facility improvements were identified and listed on
Table 7.4
. The table lists existing storage
facilities for each zone, identifies existing storage capacity deficiencies, and identifies future
storage capacity requirements to meet the needs from future growth.
Based on the storage analysis shown on
Table 7.4
, the Woodland and Glen Ayre pressure zones
are deficient under existing conditions; replacement tanks are recommended for each pressure
zone that are sized to meet the storage requirements for existing and future demands. It should
be noted that the storage requirements for pressure zones Holiday 1, Holiday 2, and Holiday 3 are
currently met by the Holiday Lake tanks. Based on direction from City staff a new tank is to be
constructed in the future to provide for the storage requirements of pressure zones Holiday 1,
Holiday 2, and Holiday 3, which are approximately 0.55 MG. This future tank also includes
additional 0.3 MG of storage capacity to account for the potential southeast quadrant
development. Should the development not be constructed, the additional capacity may allow for
operational flexibility during time of use periods.
The proposed storage reservoirs, summarized on
Table 7.5
and graphically shown on
Figure 7.6
,
are described as follows:
BR-T1:
Construct a new 1.2 MG storage reservoir at the existing Boys Ranch Tank site.
This improvement includes the demolition of the existing Boys Ranch 1 storage reservoir,
which has an existing storage capacity of 0.55 MG.
GA-T1:
Construct a new 0.25 MG storage reservoir at the existing Glen Ayre Tank site.
This improvement includes the demolition of the existing Glen Ayre Tank. This
improvement is intended to mitigate an existing storage deficiency as well as provide
storage for future demands.
ED-T1:
Construct a new 0.90 MG storage reservoir at the existing Edmundson tank site to
provide additional storage for future demands.
WD-T1:
Construct a new 0.25 MG storage reservoir at the existing Woodland Tank site.
This improvement includes the demolition of the existing Woodland Tank. This
improvement is intended to mitigate an existing storage deficiency as well as provide
storage for future demands.
HL-T1:
Construct a new 0.85 MG storage reservoir near Dunne Avenue approximately
500 feet northeast of Flaming Oak Lane. This tank is intended to provide for the storage
requirements of existing pressure zones Holiday 1, Holiday 2, and Holiday 3 following the
abandonment of existing booster stations East Dunne Number 2 and East Dunne Number
3.
7.7 PUMP STATION CAPACITY ANALYSIS
The City’s existing pump station capacity is identified in this section. Additionally, this section
identifies the existing and future pump station capacity requirements and compares it with the
existing pump station facilities in each zone and makes recommendations for new pump station
facilities.
