ANALYSIS:
Azusa Light & Water’s (ALW) Water Treatment Section operates and maintains thirteen reservoirs
throughout the distribution system for potable water storage. North Reservoir was constructed in 1976
and is a welded steel tank. ALW Staff determined that North Reservoir needed significant rehabilitation
to continue to provide safe and reliable service. In 2019 ALW Water Treatment Staff dewatered,
inspected, and cleaned North Reservoir. At the same time, ALW Water Engineering Staff invited
multiple engineering consultants to inspect the inside and outside coating and overall condition of the
reservoir. Based on the engineering analysis the most significant issues found included the need to
replace the interior and exterior coating systems, as well as address maintenance issues related to an
obsolete and deteriorating circulation system. A need for safety improvements was also identified,
including new stair railings, and a new access hatch into the tank. New seismic inlets and outlets were
designed to be installed on the reservoir. ALW staff consulted with Civiltec Engineering, Inc., under an
existing Professional Services Agreement, to prepare construction plans and specifications for
rehabilitating North Reservoir.
The scope of work included of recoating the interior and exterior of the reservoir, the reconfiguration of
the well supply and system connection piping, replacing the existing cathodic protection system,
removal of abandoned interior circulation piping, installation of a flush type cleanout manhole, replacing
and rehabilitating reservoir appurtenances, including piping, valves, flexible connections, tie-ins,
removals, abandonments, appurtenances, and all supplies, equipment, coating materials, and
transportation necessary to construct and complete the project entitled: North Reservoir Rehabilitation
Project No. W-356. All items addressed in this project will mitigate the potential risk of failure and are
projected to increase the life expectancy of the reservoir by an additional twenty-five (25) years.
On October 19, 2020, the Azusa Utility Board authorized advertisement and solicitation of bids for
Project W-356 North Reservoir Rehabilitation. Notices were placed on the City of Azusa website and
were published in the San Gabriel Valley Tribune on October 23, 2020 and October 29, 2020. Staff
received responses from thirty-four potentially interested parties, which included contractors,
subcontractors, suppliers, and plan holder agencies. A mandatory pre-bid meeting was held via
teleconference on November 17, 2020, with fifteen contractors in attendance. Two (2) parties submitted
bids by the required deadline on December 1, 2020. On December 1, 2020, at the Azusa City Clerk’s
office, bids were publicly opened outside and shown via live stream Zoom teleconference due to the
Covid-19 pandemic. At the January 25, 2021 Utility Board, the contract was awarded to Paso Robles
Tank, Inc. for a bid amount of $1,621,829. The Purchase Order was issued April 28, 2021. Submittals
for the project, procurement of materials, kick off meeting took place May 11, 2021. Due to the
pandemic there were long lead times for materials and staffing constraints. Staff issued the Notice to
Proceed on August 10, 2021 with an effective start date of August 23 2021. The reservoir was removed
from service and drained August 18, 2021. The first construction progress meeting was held on
September 1, 2021. The contract time of completion was 180 calendar days, to be completed by
December 21, 2021.
Justifiable delays due to unfavorable weather, holidays, and change order work extended the project
completion by approximately 45 calendar days. The actual completion date was extended due to
unforeseen surface preparation requirements, and material delivery delays due to Covid impact on
material manufacturing and supply chain interruptions. The rehabilitation work was completed and the
reservoir access hatches were bolted closed on March 23, 2022. The reservoir was filled on March 24,

2022. Water quality samples were taken March 31, 2022 after a seven day soak per AWWA testing
requirements. Laboratory analysis results received on April 11, 2022 confirmed an absent presence for
coliform bacteria and successful water quality results. The reservoir was returned to service on April 12,
2022, approximately 230 days after the reservoir was removed from service. This project was completed
within budget and successfully with the aid of all the Water Treatment Plant operators and ALW Water
Engineering Staff. The entire project was completed and approved by ALW on April 18, 2022.
