BACKGROUND
The City operates and maintains 11 groundwater wells, which produce an average of 14,000 acre-feet of water for Arcadia customers each year. Regular inspection and maintenance of City wells is crucial to ensuring that the wells are operating at maximum production capacity and efficiency.
The American Water Works Association (“AWWA”) is a nonprofit organization that develops and publishes standards for the proper treatment, transportation, and storage of drinking water supplies. The AWWA Standards for Water Supply Wells recommend performing preventative maintenance every 7 to 10 years, which includes removing the

well pump assembly and components. The Public Works Services Department (“PWSD”) has developed a water supply well inspection and rehabilitation program that follows these guidelines. Each year, one to two wells are selected for preventative maintenance based on the date of the last inspection, maintenance records, and the current well efficiency. Preventative maintenance performed on the City’s water supply wells protects against higher emergency repair costs and the possibility of not meeting system demands should a water supply well go out of service for an extended period.
DISCUSSION
On November 21, 2023, the City Council approved a contract with General Pump Company, Inc. for the inspection and rehabilitation of the Orange Grove Well 2A Project.
Orange Grove Well 2 is located 600’ east of Well 5 on the southeast property line of the facility, north of 29 W. Orange Grove Avenue. 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 was agreed upon by the contractor and PWSD. The original contract estimate for all work was $333,800. After the well was pulled, a more defined project cost was determined with final construction costs totaling $332,688.
The work included cleaning of the well casing, replacing the existing worn column pipe, worn or damaged shaft assembly, oil lubrication, suction with stainless steel cone strainer, sounding tube, stainless steel airline and gauge, and replacing the inadequate pump bowl assembly and motor. 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 contract have been complied with and the work has been performed to the satisfaction of the Project Manager. General Pump Company, Inc. completed the work as defined in the project plans and specifications in an efficient and timely manner.
