MEETING DATE: JANUARY 3, 2006
TO: WILLIAM A. HUSTON, CITY MANAGER
FROM: PUBLIC WORKS DEPARTMENT/WATER SERVICES DIVISION
SUBJECT: EMERGENCY REPAIR OF WEll NO.4 AT THE 17TH STREET DESALTER
SUMMARY
Well No.4 at the 17th Street Desalter recently experienced a significant drop in production. Its
original production rate was 2,200 gallons per minute (gpm). The current production rate, prior to
being taken off-line, was 800 gpm. It is critical that this well be returned to service immediately to
meet operational, emergency and fire flow requirements within Tustin's water service area.
Resolution No. 06-07 will ratify the Public Works Department's decision to dispense with Public
Works bidding requirements and pursue immediate emergency repairs.
RECOMMENDATION
It is recommended that the City Council: 1) Adopt Resolution No. 06-07, declaring that the public
interest and necessity demanded the immediate expenditure of public money to repair Well No.4 to
safeguard life, health and property; and 2) Appropriate $40,000 for installation and replacement of
pump and column, and $60,000 for potential replacement of the well motor from the Water
Operations budget.
FISCAL IMPACT
There is an adequate fund balance in the Water Operations budget. All expenses will be reconciled
in accordance with the existing Operations and Maintenance agreement between the City of Tustin
and Metropolitan Water District of Southern California.
BACKGROUND
The Water Services Division recently discovered an unexpected and significant drop in production
from Well No.4 at the 17'h Street Desalter. Layne Christensen, a well contractor, was retained to
remove the pump and motor to determine the cause of reduction in water production. It was
determined that debris was absorbed through the pump, damaging the strainer and pump impellers.
Layne Christensen was directed by staff to replace the strainer and pump impellers at an estimated
cost of $40,000. Staff feels it is prudent to plan for the possible replacement of the motor. Funds in
the amount of $60,000 have been requested.
