City of Morgan Hill Water System Master Plan 2017

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. 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 PIPELINE IMPROVEMENTS TO SERVE FUTURE GROWTH
