CC 2016-05-24_09g Well No 4 Replacement Pump and Pipe Column
MEMORANDUM
TO: CITY COUNCIL
FROM: GEOFF ENGLISH, PUBLIC WORKS DIRECTOR
BY: SHANE TAYLOR, UTILITIES MANAGER
SUBJECT: CONSIDERATION TO APPROVE THE PURCHASE OF A
REPLACEMENT PUMP AND PIPE COLUMN FOR WELL NO. 4
DATE: MAY 24, 2016
RECOMMENDATION:
It is recommended the City Council approve the purchase of a replacement vertical
turbine pump and pipe column for Well No. 4 in the amount of $22,000 from Filiponi &
Thompson Drilling.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
The funding for the backup pump and pipe column is budgeted in FY 2015/16, in the
amount of $27,500.00. Restoration work will involve approximately 40 work hours.
BACKGROUND:
Well No. 4 was drilled in 1964. The pump and pipe column were replaced in 1992.
During the last year the well lost production by 50%. The City received three (3) written
quotes (Attachment 1) to replace the pump and pipe column.
ANALYSIS OF ISSUES:
Well No. 4 is part of the City’s Drinking Water Well System. The system consists of six
(6) wells which pump water from the Santa Maria Groundwater Basin, and two (2) wells
which pump from the Pismo Formation. Well No. 4, one of the wells that pumps from
the Santa Maria Groundwater Basin, produces 500 gallons per minute. Due to the age
of this well, 52 years old, the well casing will be video inspected prior to any new “down
hole” equipment installation to assure the casing is still in good condition.
ALTERNATIVES:
The following alternatives are provided for the Council’s consideration:
1. Approve a purchase order in the amount of $22,000.00;
2. Do not approve the purchase order;
3. Modify as appropriate and approve staff’s recommendation; or
4. Provide direction to staff.
