BACKGROUND
The Orange County Sanitation District's (OC San) Headworks Bar Screen Facility provides vital preliminary treatment to all incoming wastewater by removing trash and debris that would otherwise damage downstream treatment equipment. Water is supplied from the adjacent Influent Pump Station and used in the sluiceways to remove and transport the debris from the bar screens for disposal. Plant No. 2 Headworks was constructed in 2012 under Project No. P2-66, Headworks at Plant No. 2.

PROPOSED SOLUTION
Award a construction contract for Influent Pump Station Plant Water Piping Repair at Plant No. 2, Project No. FR2-0029. This project will replace existing, failed underground sections of pipe to provide reliable sluice water to the Bar Screen Facility.
