SUBJECT: Resolution Approving the Purchase of One Flygt Submersible Pump for the
Tertiary Feed Pump Station
RECOMMENDATION
It is reconmiended that the City Council adopt the attached Resolution Approving the Purchase
of One Flygt Submersible Pump for the Recycled Water Tertiary Feed Pump Station.
BACKGROUND
The Tertiary Feed Pump Station is equipped with two 35 horsepower (HP) full service Flygt
submersible pumps and one 7.5 HP low demand Flygt submersible pump. The pump station was
designed to meet peals demand with both large pumps in service, and to provide process water
for the treatment plant while meeting minimal recycled water demand with the small pump. The
pump station conveys effluent from the wastewater treatment secondary clarifiers to an elevated
coagulation and flocculation tank. The water then flows by gravity through sand filters and an
ultraviolet disinfection system to the Recycled Water Storage Basin prior to distribution. The
City's recycled water users include dairies, vineyards, two golf courses, multiple schools and
parks, and the airport. Currently, there is no back-up pump should either of the full service
pumps fail.
The Tertiary Feed Pump Station relies on both large pumps to meet recycled water demand from
May through September. During these months, the two large pumps operate concurrently
approximately 20 hours each day. The pump station was designed without a standby pump;
therefore, a readily available spare pump is necessary to ensure pump station reliability. There
are no existing backup pumps that match this application and delivery of a new pump takes nine
to ten weeks; therefore purchasing a shelf spare is prudent.
The spare pump could be installed quickly in the event of a pump failure, or installed when an
existing pump is taken out of service for maintenance. This would improve pump station
reliability, provide flexibility for scheduled maintenance, and minimize potential impacts of a
Pump failure on recycled water production. The capacity of the Tertiary Feed Pump Station is
2.6 million gallons per day with one pump in operation, and 5.2 million gallons per day with two
pumps in operation. Operating the pump station with a single pump during the summer would
not only result in severe use restriction on all users, but the City would lose an estimated $1,500
per day in revenue generated by the sale of recycled water.
Shape Inc. is the sole regional supplier for Flygt pumps purchased by municipalities. The Public
Works and Utilities Department has standardized its submersible pump specifications to
maximize flexibility and convenience, and to minimize cost in operating and maintaining the
department's pump stations. Using a standard pump specification has these advantages:
1. Match existing equipment
2. Reduce spare parts inventory
3. Reduce training needs by minimizing the variation of equipment
4. Improve consistency in operation and maintenance
5. Improve reliability by using equipment with a proven record of reliability
6. Reduce long-term costs for operation and maintenance by having interchangeable parts
for all prmip stations
Flygt pumps are currently the industry standard for quality and performance. Flygt pumps at our
facilities are reliable and we do stock a replacement pump for some of our critical sewer pump
stations. This sole source purchase is consistent with Resolution 94-11 N.C.S. (see attachment 2)
which authorizes staff to sole source Flygt submersible pumps for all future sewer pump station
projects.
FINANCIAL IMPACTS
The cost of one submersible Flygt pump is $32,168.65. The pump will be funded through the
recycled water account 6600.66500.62210. The current balance in the account is $35,000.
