City of Morgan Hill
Water System Master Plan
7.7.1
Existing Pump Station Capacity Requirements
Existing pump station requirements were identified for each existing pump station and are
summarized on
Table 7.6
. The table lists the existing pump station capacities and identifies the
required capacity, based on the City criteria. The existing pump station capacity analysis indicates
the City’s current pump stations have adequate capacity to meet existing requirements.
7.7.2
Future Pump Station Capacity Requirements
Future pump station requirements were identified for each existing pump station and are
summarized on
Table 7.7
. This table identifies the future pump station capacity requirements
based on the buildout demands. At the buildout of the master plan the existing pump stations East
Dunne Number 1, East Dunne Number 2, and East Dunne Number 3 are going to be abandoned
and replaced with a new pump station; this proposed pump station will serve a proposed Holiday
tank. Additionally, a new pump station is recommended at the proposed Holiday Lake tank site to
serve the existing Holiday Lake tanks. The proposed pump stations, summarized on
Table 7.8
and shown graphically on
Figure 7.6
, are described as follows:
NH-PS1:
Replace existing pump stations East Dunne Number 1, East Dunne Number 2,
and East Dunne Number 3 with one new pump station. This pump station is planned to
have three 900 gpm pumps for a total pump station capacity of 2,700 gpm. It should be
noted that the construction of this pump station will require trigger the construction of a
PRV on Thomas Grade Lane, approximately 1,100 feet west of Gnarled Oak Lane. This
PRV improvement is listed as HL-PRV1 in
Table 7.9
.
HL-PS1:
Construct a new pump station at the proposed Holiday tank site. This pump
station is planned to have four 550 gpm pumps for a total pump station capacity of 2,200
gpm.
7.8 PIPELINE IMPROVEMENTS TO SERVE FUTURE GROWTH
The buildout of the 2035 General Plan includes development outside of the extents of the existing
domestic water distribution system. Distribution pipelines are recommended to serve future growth
as well as increase the hydraulic reliability of the domestic water distribution system. Each
pipeline improvement is assigned a uniquely coded identifier, which is intended to aid in defining
the location of the improvement for mapping purposes. These identifiers reflect the pressure zone,
improvement type, and sequence in the improvement schedule. The pipeline improvements are
summarized on
Table 7.9
and described in detail on the following pages.
7.8.1
Boys Ranch Pressure Zone
This section documents pipeline improvements within the Boys Ranch Pressure Zone.
BR-P1:
Construct a new 10-inch pipeline in future right-of-way between Cochrane Road
and Coyote Road.
