AGENDA TITLE: Adopt Resolution Authorizing City Managerto Execute Purchase Orderwith
Eaton Pumps Sales and Service, of Woodland, for Repairsto City Water Well
No. 7 ($36,640)
MEETING DATE: May 19, 2010
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt a resolution authorizing the City Manager to execute a
purchase order with Eaton Pumps Sales and Service, of Woodland,
for the repairs to City Water Well No. 7, in the amount of $36,640.
BACKGROUND INFORMATION: City Water Well No. 7, located at 2101 West Turner Road, failed in
October 2009. It was originally determined the pump motor had
failed due to storm damage, and the pump motorwas repaired.
While attempting to start the new motor, staff found the pump shaft
was frozen, rendering the well inoperable. Well No. 7 was constructed in 1978 and produces around
1,160 gpm of very high-qualitywater. Generally, well production ranges from 800 to 2,070 gpm per well.
In February 2010, proposals were requested from Eaton Pumps Sales and Service (Eaton Pumps) and
Layne Christensen Company to remove the pump assembly, inspect the condition of the well, and
evaluate the damage to the pump assembly. The lowest cost proposal for this work was submitted by
Eaton Pumps in the amount of $4,795.
Eaton Pumps completed their evaluation of the pump assembly and well and reported that the line shaft
bearings in the pump assembly require replacement, the slots in the casing are obstructed by significant
biological growth and there is approximately 37 feet of fine silt in the bottom of the well that requires
removal.
Well assembly repairs are required and include replacing the existing line shaft bearings, removing the
fine silt and biological growth, steam -cleaning the casing pipe, checking the line shaft for straightness,
and reconditioning the well. Reconditioning is a process that uses chlorine and airlift swabbing to clean
the casing slots and to remove accumulated silt and biological growth from the casing and gravel pack
from the affected areas.
Considering the importance of Well No. 7 to the City's water supply, staff recommends executing a
purchase order with Eaton Pumps for the above-described repairs to City Water Well No. 7, in the
amount of $36,640.
FISCAL IMPACT: There will be no change in operations costs.
FUNDING AVAILABLE: Wate Fund (1 453) — $36,640
