body
BACKGROUND
Headworks facilities at Orange County Sanitation District (Sanitation District) Plant Nos. 1 and 2 remove large pieces of trash and debris that would otherwise damage downstream treatment equipment. On occasion, combustible gas or hydrocarbon vapor in the incoming wastewater accumulates in the Headworks building. These gases pose a danger to staff and facilities if their concentration exceeds their lower explosive limit.
RELEVANT STANDARDS
* Comply with California Public Contract Code Section 20103.8, award construction contract to lowest responsive, responsible bidder
* Commitment to safety & reducing risk in all operations
PROBLEM
Explosive gases can accumulate in the Headworks and would not be detected.
PROPOSED SOLUTION
Award a Construction Contract for Headworks Explosive Gas Monitoring Systems at Plant Nos. 1 and 2, Project No. FE18-11, to install explosive gas monitoring systems at each plant. This system will provide an early warning of a potential hazard, such as combustible liqui...
