COUNCIL GOAL AND PREVIOUS, COUNCIL ACTION
Council approved purchase of val14ble frequency drive units for the Allen Filter Plant on November 5,
1990 ,
RECOMMENDED :.CTION
The Utilities De~artment staff recommends Council approval by Resolution for the purchase of a
variable frequency drive and amp surge suppressor from Ryal Electric in the amount of $30, 112.40 .
BACKGROUND, ANALYSIS , AND ALTERNATIVES IDENTIFIED
The Unlor, Avenue Pump Station has three 250 hp pumps. One pump has a soft starter for energy
savings , bu1 is on a fixed speed . The other two motors share one variable frequency drive that allows
running only one pump at a time . Variable speed drives are needed to match the flow produced to the
flow required by the pretreatment units . The Un ion Avenue Pump Station Is the sole water provider
from the S Platte River to the Allen Filter Plant, as ide from the City Ditch that can be used only In the
summer. This is made even more critical because of the new construction at the Allen Plant ; the
North Reservoir will be out of service for an extended period of time for cleaning and maintenance .
Even aft er maintenance is completed , the North Reservoir will only be used as an emergency water
supply,
The amp surge suppressor will be required for the periodic power surges at Union Ave from Public
Serv ice and will pro .eel the integrity of the drive.
FINANCIAL IMPACT
The suggested supplier, Ryal! Electric is recommended as a sole •sourc~ supplie r in the amount of
$30 ,112.40 . Ryal! Electric has provided a written statement that they are the sole supplier and the
quoted price is the lowest available . They will not be selling the same equipment to anyone e!se (like
a sub-contractor) at a cheaper price . We '1ave previously purchased 12 VFD drives from this supplier
and found the equ ipment to be satisfactory with exemplary service from both the local supplier and
the corporate headquarters . In an emerge ncy, technical support and parfs would be available in 24
hours from their Golden office .
