FROM: BRUNO RUMBELOW, CITY MANAGER I°
MEETING DATE: AUGUST 2, 2011
SUBJECT: APPROVAL OF THE EMERGENCY REPAIR OF HIGH
SERVICE PUMP MOTOR AT THE WATER TREATMENT
PLANT..
RECOMMENDATION:
City Council consider adopting a resolution authorizing and ratifying the City Staff's
emergency purchase of pump repair services from T -Gray Electric in an amount of
$22,690.80 for the repair of one of the two 6.8 MGD Treated Water High Service Pumps
at the Water Treatment Plant and take any necessary action.
FUNDING SOURCE:
Funding for this repair is available in the Utility PCMF account 200- 43360 - 534 -0.
BACKGROUND:
We experienced an unexpected failure of one of our treated water high service pump
motors on July 7 at the Water Treatment Plant (WTP). This significantly limited our
pumping capacity at the WTP during the peak demand season. The treated water
pumps supply potable water to the distribution system for consumption.
The failure of this pump, one of the two largest pumps at the plant representing nearly
25% of the plant's pumping capacity, would not allow us to meet the peak demands that
are placed upon our water system during summertime usage.
Staff contacted T -Gray Electric to evaluate the problems with the motor and upon
inspection they discovered that the pump had a bad winding and the motor needed to be
re -wound to correct the problem. Staff authorized T -Gray Electric to perform the repairs
to the motor on July 8 and the pump was placed back into service on July 18.
Staff recommends approval.
