SUBJECT: Submittal of Plans and Specifications for "Water Main
Reconstruction Project: Hathway Pumps, Grand PRV, Warren
CV, Flora CV; City Plan Nos. M-30P, N-2.3P, N-24P, N-26P"
RECOMMENDATION:
Approve plans and specifications, authorize staff to
advertise for bids and authorize CAO to award contract
BACKGROUND
During the development of,the Water Management Plan, staff
evaluated present and future water delivery capabilities. There
are two basic transmission modes, the gravity system and the pumped
system. The pumped system raises the water 124 feet from the
gravity system and is very near its limit on pumping capacity. The
Hathway pumps will raise the water about 20 feet from the gravity
system to furnish water to Reservoir Number 1, Terrace Hill and the
proposed tank on Islay Hill. This will reduce the loading on the
pumped system and reduce energy consumption by supplying these
lower level reservoirs. This water will require only about 17% of
rl
the previous pumping effort.
The Grand Avenue pressure reducing valve will provide for
reinforced service to the Andrews Street pressure zone and remove
some of the load from our most overloaded water transmission system
along Johnson Avenue.
The Warren check valve and the Flora check valve will provide
automatic backup to existing neighborhoods that rely on a single
source pumping system.
These projects are very similar in the nature of their construction
and are assembled into one bid package to provide a lower unit
cost. They have been given an EIR clearance by the Planning
Department. Status: Categorical Exemption.
