The Orange County Sanitation District (Sanitation District) owns and operates the Seal Beach Pump Station which was built in 1972 and is near the end of its useful life. Seal Beach Pump Station Replacement, Project No. 3-67, is now in design, but will not be completed until 2026.
RELEVANT STANDARDS
* Comply with California Public Contract Code Section 20103.8: Award Construction Contract to lowest responsive, responsible bidder
* Achieve less than 2.1 sewer spills per 100 miles
* Ensure the public's money is wisely spent

Such a failure in a wet weather event could cause a sewer spill. The poor condition of these valves requires them to be replaced prior to the Seal Beach Pump Station Replacement Project.
PROPOSED SOLUTION
Award a Construction Contract for Seal Beach Pump Station Isolation Valve Replacement, Project No. FRC-0004, to replace 13 isolation...
