Master Plan
The
District’s three water storage tanks comprise 1.31 million gallons
(MG) of storage. To meet
existing storage needs, for operational, fire and emergency storage,
approximately 2.3 MG of storage is required, resulting in a present-day
deficit of 0.84 MG. At
system build-out, this deficit is projected to reach 1.01 million
gallons. A new water
storage tank is recommended at the “Highland” site.
This new tank should be sized to meet build-out demands, and
designed to match hydraulic grade with the existing 16th
Street tanks. Further consideration should be given to abandoning the 10th
Street water storage tank, pending completion of additional seismic and
geotechnical evaluations. Should the cost to retrofit this tank be
significant compared to the cost of developing new storage, the district
should consider consolidating the 10th Street
storage volume at the future Highland tank site.
The resulting tank at Highland would be 1.4 MG.
Consolidating the 10th Street storage at the Highland
tank site would be beneficial for two main reasons:
- The
10th Street tank is lower in elevation than the 16th
Street tanks, necessitating pumping of water from the 10th
Street tank into the system. It
would be desirable to eliminate the need for these pumps to simplify
operations and be more energy efficient.
.
- The
10th Street tank is nearing 40 years of age, and the cost
of repairs and re-coating could
be significant, pending completion of the seismic and
geotechnical evaluations.
