centers. This project will allow SBWRF to
meet the Class 1 requirement.
The backup power supply will be provided via
two generators connected via paralleling
switchgear. The paralleling switchgear
allows the generators to operate as a single
unit with the added ability to shed electrical
loads if one of the generators was
incapacitated. Two generators will be
installed at this time with a third future
generator installed as power demand
increases with completion of future plant
expansion projects.
Engineer: In-House
Contractor: In-House
Eight lift stations have been prioritized for
rehabilitation due to existing conditions of the
various components at each station. This
project will be designed and constructed in 2
phases:
Phase I: LS-64, LS-5B, LS-20B
Phase II:LS-76, LS-125, LS-15, LS-17P,LS-
18P
Rehabilitation efforts to include pump &
piping replacement, wetwell repair & coating,
electrical upgrades, SCADA upgrades,
fencing improvements, and other
rehabilitation efforts as required at each
station.
Phase I:
LS 5B construction is
underway. The Startup is
scheduled for July 23, 2012.
LS 20B and LS 64
construction have not been
initiated yet.
Phase II:
Draw down test on all Phase
II lift stations has been
completed. Survey has been
completed for all lift stations.
Hydraulic modeling and 60%
design is underway.
Phase I:
LS 5B: Pumps, piping, top
slab have been installed;
wetwell has been coated.
Electrical construction is
underway.
Phase II:
60% Design has been
initiated.
