DATE: January 13, 2020
SUBJECT
Consider adoption of an ordinance of the City of Denton, a Texas home-rule municipal corporation,
authorizing the City Manager to execute a contract with Walker Industrial, LLC, for the supply of two (2)
500 horsepower variable frequency drives at the Lake Ray Roberts Water Treatment Plant (LRRWTP);
providing for the expenditure of funds therefor; and providing an effective date (IFB 7213 – awarded to
Walker Industrial, LLC, in the not-to-exceed amount of $275,035.61).
IFB INFORMATION/BACKGROUND
The LRRWTP was constructed in 2003 to increase the potable water supply for the City of Denton residents.
The High Service Pump Station (HSPS) is the final component of the treatment plant, pumping 30%-50%
of the City’s potable water to the City’s distribution system. The HSPS operates with two identical pumps
controlled by Variable Frequency Drives (VFD). These VFDs allow operators to control the flow rate of
water to match the system demand. The mechanical components of the pumps are in good condition;
however, the VFDs are reaching their end of life.
These VFDs became obsolete in 2006 when the original manufacturer was acquired by Siemens.
Replacement parts are now no longer available. Although the VFDs continue to operate, any unforeseen
failure will result in lengthy downtime for the plant while new VFDs are manufactured. The only viable
planned maintenance action is to fully replace prior to a failure.
Replacement must be completed in the winter/low water demand months of November through May to
allow the plant to shut down one pump at a time. The manufacture of the new VFD units is expected to take
12 weeks.
Invitation for Bids was sent to 70 prospective suppliers of this item. In addition, specifications were placed
on the Materials Management website for prospective suppliers to download and advertised in the local
newspaper. One (1) bid meeting specification was received by Walker Industrial, LLC.
