REHABILITATION CAPITAL IMPROVEMENT PROJECT
BACKGROUND:
On January 8, 2019, Azusa Well No. 2 was taken out of service for inspection as part of Azusa
Light & Water's (ALW) Well Rehabilitation Program. On February 25, 2019, the Azusa Utility
Board awarded Task Order 9, under an existing Master Maintenance Services Agreement, to
General Pump Company, who pulled the well and performed a video inspection. To restore
production capacity and improve efficiency and reliability, the well was rehabilitated with a new
pump, column, oil lubricated shaft, bowl assembly and suction and discharge piping. This project
has been completed and ALW is now required to file a Notice of Completion with the Office of
the County Recorder of Los Angeles.

ANALYSIS:
Well 2 was originally constructed in 1921 with a capacity of 3,000 gallons per minute (GPM)
and historically produced 2,000 acre feet per year. ALW authorized General Pump Company,
operating under a Master Maintenance Services Agreement, to pull the pump, video log the
entire 252 feet of the well, and provide recommendations to increase reliability and efficiency.
Since its last rehabilitation in 2007, Well 2 has seen a gradual decrease in production from
approximately 2,700 GPM to approximately 1,100 GPM. After the recent rehabilitation, Well 2
has increased production by 1,500 GPM and the overall efficiency has increased by 25%.
Water Division worked with General Pump to expedite the repair work in anticipation of higher
demand during the summer months. Once the materials and equipment were installed, the
Production Section operated Well 2 to verify compliance for performance and water quality.
Bacteriological samples were collected and analyzed, confirming the water met all applicable
quality requirements. On September 23, 2019, Well 2 was placed back into service and is
currently producing approximately 2,600 GPM.
FISCAL IMPACT:
The Well 2 Rehabilitation Capital Improvement Project was assigned to the Water Division’s
Capital Improvement Program budget Account No. 32-80-000-721-7130/72119C, for an amount
not-to-exceed $149,875, which included a 10% contingency. The project was completed on
schedule and within budget at a total cost of $140,236.44.
