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 Accept Live Oak Well Rehab Project September 2, 2014 Page 2 of 2 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.
