Award a contract to Academy Electric, Inc. for replacement of a variable frequency drive in an
amount not to exceed $40,000.
DISCUSSION
The Public Works Agency's Water Resources Division uses a variable frequency drive (VFD) to
regulate the pressure of water pumped from the City's wells. The variable frequency drive at
Well No. 31 failed and its internal switching controls were burned beyond repair. A new
replacement drive is required. Well 31 is a critical well that supplies water and maintains water
system pressure in the east side of the City's distribution system. The drive is needed to
maintain the water system pressure and to increase the waters systems capacity to absorb
pressure surges. Replacing Well 31 VFD is needed as soon as possible to prevent water
pressure surges and to better regulate the water distribution system pressure.
Without the VFD regulating system pressure, hydraulic pressure waves could occur and cause
large water main breaks that disrupt water service and damage City infrastructure. Per Sec. 2-
807 of the Santa Ana Municipal Code, procurements of urgent necessity for the preservation of
life, health, or property may be authorized without observing bidding requirements. The Water
Resources Division requests authorization to initiate the necessary repairs.
