stainless steel casing, glass bead packing, pump, column, oil lubricated shaft, bowl assembly,
check valve, and pump-to-waste piping. This project has been completed and Azusa Light &
Water (ALW) is now required to file a Notice of Completion with the Office of the County
Recorder of Los Angeles County.

2) Approve the Notice of Completion; and
3) Authorize the Mayor to execute the Notice of Completion on behalf of the City; and

ANALYSIS:
ALW’s Well 1 was constructed in 1975 with a capacity of 3,000 gallons per minute (GPM) and
an average production of 2,800 acre feet per year. The well was last inspected in 2003 and is
currently on a programmatic cycle for rehabilitation to maintain efficiency and promote
longevity. Since the last rehabilitation work in 2003, Well 1 has lost 800 gallons per minute of
production, and overall efficiency is at 53 percent. On March 23, 2020, the Azusa Utility Board
awarded Task Order 10, under an existing Master Maintenance Services Agreement, to General
Pump Company for Well 1 rehabilitation work. The project included pulling the well and video
inspecting the entire 350 foot depth to provide recommendations for repair. The video inspection
revealed the existing mild steel casing to have deteriorated through the entire depth of the well,
with large holes visible throughout.
After a complete assessment, General Pump determined required improvements, including:
installation of a new stainless steel casing, glass bead packing, pump, column, oil lubricated
shaft, bowl assembly, impellers, cone strainer, check valve, and pump-to-waste piping. The liner,
strainer, impellers, bowl bolting, shaft coupling, line shaft, and head shaft were replaced with
stainless steel material to ensure long-life and limited corrosion.
After rehabilitation, bacteriological samples were collected and analyzed, confirming the newly
pumped water met all applicable water quality requirements. On July 20, 2020, Well 1 was
placed back into service. As a result of this rehabilitation project, current production has
increased by approximately 700 GPM to 3,300 GPM, and overall efficiency has increased by
25%.
FISCAL IMPACT:
The Well 1 Rehabilitation Capital Improvement Project was budgeted in the Water Division’s
Capital Improvement Program, Account No. 32-80-000-721-7130/72120A, for an amount not-to-
exceed $343,310, which included a 10% contingency. The project was completed on schedule
and within budget.
