BACKGROUND
The Seal Beach Pump Station currently discharges all flow through a single 42-inch diameter ductile iron force main that is approaching the end of its useful life. A second 30-inch force main exists. This second pipe is made of a material know to fail catastrophically. It was removed from service approximately four years ago. The Orange County Sanitation District (Sanitation District) was compensated for this faulty pipe material by the original manufacturer many years ago.
This project will replace the two force mains with two parallel 36-inch high-density polyethylene pipes. These force mains run from the Seal Beach Pump Station at the intersection of Seal Beach Boulevard and Westminster Boulevard in the City of Seal Beach, to the intersection of Westminster Boulevard and Rancho Road in the City of Westminster, a distance of approximately 14,000 feet.
RELEVANT STANDARDS
• Achieve less than 2.1 sewer spills per 100 miles
• Comply with California Public Contract Code Section 20103.8, award construction contract to lowest responsive bidder
PROBLEM
The existing unused 30-inch force main is not safe to use due to its poor condition. The 42-inch ductile iron force main is oversized for normal flows, which causes solids to settle and accumulate inside the pipe. That force main has also experienced corrosion and is approaching the end of its useful life.
PROPOSED SOLUTION
Award a Construction Contract for the Westminster Boulevard Force Main Replacement, Project No. 3-62, which will replace the two existing force mains reducing the risks of spills, allowing the force mains to be taken out of service for cleaning and repairs, and reduce the accumulation of solids in the pip due to low velocities.
TIMING CONCERNS
This project includes seasonal work restrictions to ensure that peak wet weather flows can be accommodated throughout construction. Delaying project award will reduce available durations to perform portions of the work that must be completed in advance of the wet season that begins in October 2021.
RAMIFICATIONS OF NOT TAKING ACTION
Not replacing the force mains will increase maintenance actions and will eventually result in the failure of this critical asset. A force main failure would cause a significant sewer spill and will require significant bypassing to perform the repair.

CEQA
The project is exempt from CEQA under the Class 1, 2, 3, and 4 categorical exemptions set forth in California Code of Regulations sections 15301, 15302, 15303, and 15304 because the project involves repairs, replacement, limited construction of new facilities, and minor alteration of existing facilities involving no expansion of use or capacity. A Notice of Exemption will be filed with the OC Clerk-Recorder after the Sanitation District’s Board of Directors approval of the construction contract.
FINANCIAL CONSIDERATIONS
This request complies with authority levels of the Sanitation District's Purchasing Ordinance. This item has been budgeted. (FY 2019-20 Budget Update, Appendix A, Page A-7) and the budget is sufficient for this action.
