E-3 Approved Utility Board 7/26/21 Approve Notice of Completion for W-354 Triangle Flow CIP July 26, 2021 Page 2 ANALYSIS: Several critical water transmission mains intersect at Sierra Madre Avenue and San Gabriel Canyon Road, referred to as the “Triangle.” One of the transmission mains is a 24-inch, low pressure line, that carries treated effluent water from the Joseph F. Hsu Water Filtration Plant (Filtration Plant). This line connects to another 24-inch transmission main coming from Azusa Light & Water’s (ALW) well field; in particular Well 2 and Well 3. The pressure routinely fluctuates on the transmission main coming from the well field, which affects the flow of water coming from the Filtration Plant. Currently, when the flow is changed at the Filtration Plant, the existing isolation valves at the “triangle” must be adjusted manually to compensate for the well field fluctuations. The existing valves that were installed for isolating the pipelines are not designed to control flow. ALW staff consulted with Stantec Consulting Services, Inc., under an existing Professional Services Agreement, to prepare construction plans and specifications for automation of the current site. The finished project involved constructing a new automated flow control structure, including: installation of power to the site, electrical, grounding, electrical meter, instrumentation, remote terminal unit (RTU), SCADA communication hardware, a 16-inch Cla-Val flow control valve, connections, tie-ins, removals, abandonments, appurtenances, street restoration, landscape restoration, traffic control, and all supplies, equipment, shoring, and transportation necessary to construct and complete the project titled: Triangle Water Flow Control Structure Project No. W- 354. On September 21, 2020, the Azusa Utility Board authorized advertisement and solicitation of bids for Project W-354 Triangle Flow Control Structure Capital Improvement Project. On October 27th, at the Azusa City Clerk’s office, bids were publicly opened outside and showed via live stream through Zoom teleconference. At the November 23, 2020 Azusa Utility Board, the contract was awarded to Fraijo Brothers, Inc., for a bid amount of $242,407.

Staff issued the Notice to Proceed on April 19, 2021 with an effective start date of May 3, 2021. The pre-construction meeting was held on May 6, 2021. The contract time of completion was 60 calendar days, to be completed by July 2, 2021. Fraijo Brothers finished the project ahead of schedule and under budget on June 14, 2021.
