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 seven to ten years, which includes removing
the well pump assembly, video inspecting the pump casing, and performing a

comprehensive inspection of 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 reduces the likelihood of insufficient supply should a water
supply well become inoperable for an extended period.
DISCUSSION
On April 4, 2023, the City Council approved a contract with General Pump Company, Inc.
for the inspection and rehabilitation of the Orange Grove Well 5 Project. Orange Grove
Well 5 is a submersible pump and motor located on the southwest corner of the water
facility, just north of Fire Station 107. The project began with removal and inspection of
the well motor, pump, and appurtenances, 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
$289,400. After the well was pulled, a more defined project cost was determined with final
construction costs totaling $286,279.
The work included cleaning of the well casing, replacing the existing worn column pipe,
worn or damaged submersible flat cable, check valve, 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.
ENVIRONMENTAL ANALYSIS
This well inspection and rehabilitation project is considered a Class 1 exemption as
defined in Section 15301(b) of the California Environmental Quality Act, since the project
