SUMMARY
On November 19, 2013, the City Council awarded a contract to General Pump
Company in the amount of $164,680 for the Inspection and Rehabilitation of the Live
Oak Well Project. The terms and conditions of this project have been complied with and
the work has been successfully completed for a total project cost of $130,461. It is
recommended that the City Council accept all work performed by General Pump
Company as complete and authorize the final payment to be made in accordance with
the contract documents.
DISCUSSION
The City operates and maintains 14 groundwater wells, which produce an average of
16,500 acre -feet, or 5.4 billion gallons, of water to City of Arcadia customers each year.
Regular inspection and maintenance of City wells is crucial to ensuring that municipal
water wells are operating at maximum production capacity and efficiency, and to avoid
unscheduled shut -down of municipal water wells.
On November 19, 2013, the City Council awarded a contract to General Pump
Company in the amount of $164,680 for the Inspection and Rehabilitation of the Live
Oak Well. The project began with removal and inspection of the well motor, shaft, and
pump, and video inspection of the well casing. Based on this inspection, a scope of

work consistent with the contract documents and bid schedule was prepared and
agreed upon by the contractor and the Public Works Services Department.
The work included cleaning of the well casing; replacing the existing column pipe with a
larger diameter pipe to reduce friction and increase efficiency; replacing worn or
damaged line shaft sections, couplings, and line shaft retainers; rewinding of the electric
motor; and replacing the worn pump bowl assembly. Following re- assembly and
installation of the well equipment, the well was disinfected and water quality samples
were taken, tested, and approved, in accordance with California Department of Public
Health requirements.
All terms and conditions of this project have been complied with and the work has been
completed to the satisfaction of the Public Works Services Department for a total project
cost of $130,461. As a result, overall efficiency of the well was increased and the
energy savings from the well rehabilitation work is estimated to save the City
approximately $5,000 annually in electrical costs. In addition, Southern California
Edison has approved an incentive payment of $7,500 as part of their Energy Smart
Program for the installation of a new pump bowl assembly and reducing head loss in the
column pipe.
FISCAL IMPACT
This project is included in the Fiscal Year 2013 -14 Capital Improvement Program with a
total budget of $250,000. The original contract estimate for all work was $164,680.
Once the well was pulled, a more defined project cost was determined. The final
construction cost of the project was $130,461, which is within the approved budget.
Additionally, due to the energy efficiency improvements from this project, the City will
receive a one -time incentive check of $7,500 as part of Southern California Edson's
Energy Smart Program and expects to save approximately $5,000 in annual energy
costs.
RECOMMENDATION
It is recommended that the City Council accept all work performed by General Pump
Company for the Inspection and Rehabilitation of the Live Oak Well Project as complete
and authorize the final payment to be made in accordance with the contract documents.
