body
BACKGROUND
The Orange County Sanitation District (OC San) Bar Screen Facility at Plant No. 2 Headworks was constructed under Project No. P2-66 in 2012. The facility includes six inlet gates that isolate and divert flows into the corresponding six bar screens. After completion of Project No. P2-122 in 2022, flows at the Bar Screen Facility were split into two streams: non-reclaimable and reclaimable. Non-reclaimable flows are diverted to inlet gates/bar screens 1, 2, and 3; reclaimable flows are directed to inlet gates/bar screens 4, 5, and 6.
RELEVANT STANDARDS
• Maintain a proactive asset management program
• 24/7/365 treatment plant reliability
• Meet volume and water quality needs for the GWRS
PROBLEM
The Plant No. 2 Bar Screen No. 4 inlet gate provides upstream flow isolation and diversion to bar screen 4. The gate assembly is no longer functional and needs replacement.
PROPOSED SOLUTION
Approve a Sole Source Purchase Order to Misco Water, for the direct replacement of inlet gate 4 assembly.
TIMING CONCERNS
Due to the criticality of this process area, timely procurement and installation of the replacement gate are essential to ensure operational readiness and reliably support volume and water quality needs for the GWRS.
RAMIFICATIONS OF NOT TAKING ACTION
Timely replacement of the inlet gate assembly is needed to maintain reliable operations of Bar Screen No. 4 and to reliably support water quality needs of GWRS.
PRIOR COMMITTEE/BOARD ACTIONS
February 2021 - Approved the addition of Fontaine-Aquanox to the pre-approved OEM (Original Equipment Manufacturer) Sole Source List.
ADDITIONAL INFORMATION
Misco Water is the sole authorized service vendor for OC San’s Fontaine-Aquanox gate assemblies. A 10% contingency is requested in the event of pricing changes due to tariffs, delays in placing the order beyond quote availability, or other unforeseeable changes.
