DISCUSSION
On March 12, 2012, a notice inviting bids was advertised for variable frequency drives and motor
control center upgrades. Of the six bids received, staff recommended awarding contracts to the
three vendors with the lowest bids, to allow for competitive quotes on any given job. On May 7,
2012, Council approved the award of contracts to Carter Industrial Automation, Inc., Academy
Electric, Inc., and Hydro Industrial Electric Corp., for a one -year period with provision for two one -
year renewals. The first one -year renewal was approved by Council on April 15, 2013. Staff is
recommending approval of this second contract renewal. Carter Industrial Automation, Inc., and
Academy Electric, Inc., have agreed to renew their contracts without an increase in price, while
Hydro Industrial Electric Corp. raised their hourly rates by one percent. The aggregate contract
amount of $500,000 is based on expenditure projections for this final contract period.
The Public Works Agency operates 20 active water wells and seven water pumping stations to
supply the City's drinking water. In order to maintain a smooth running water system, staff has
upgraded many of the water facilities with Variable Frequency Drives (VFDs) and Motor Control

Centers (MCCs) with programmable logic controllers. These devices monitor and control the
pumps and motors that produce the City's potable water. Additionally, the equipment reduces
the amount of electricity consumed to power the pumps and motors. Updating aging pumps and
well controllers helps to operate the water system more efficiently and allows staff to improve
control of the pressure and flow of water throughout the City.
The Water Resources Division staff has identified both the East and Crooke Pumping Stations as
requiring new MCCs and VFDs. Both pumping stations were completed in 1970 and require a
number of upgrades, including electrical panel replacements to modernize stations. Additionally,
both stations are connected to reservoirs and consequently require additional components to
complete the upgrades. Given the number of upgrades, the cost to modernize these two pump
stations is significantly higher than previously upgraded water wells.
Replacing the MCCs and VFDs will allow the water production operators to control the pumps
and motors more effectively, and assist in accurately responding to daily water demand
fluctuations. In addition to the purchase of upgraded equipment, the vendors provide specialized
electrical services which are periodically required at City water wells and water pumping stations.
