BACKGROUND
The Orange County Sanitation District (OC San) collects and processes approximately 180 million gallons of wastewater every day. Cleaning this water results in concentrated solids. In December of 2021 the Board approved a demonstration project for a new type of solids treatment technology called Supercritical Water Oxidation.
This recommended Construction Contract will install pads for the solids preprocessing module and Supercritical Water Oxidation module, install a temporary trailer to serve as a control center for the demonstration project, and install all necessary process connections and utilities.
RELEVANT STANDARDS
• Comply with California Public Contract Code Section 20103.8, award construction contract to lowest responsive, responsible bidder
• Provide technology leadership to the wastewater industry
• Search for technology solutions to neutralize constituents of emerging concern
PROBLEM
In order to support the approved demonstration project, a plant site must be prepared to install the approved demonstration unit currently being manufactured. This necessary site preparation work is considered public works construction.
PROPOSED SOLUTION
Award a Construction Contract for Supercritical Water Oxidation Demonstration at Plant No. 1, Project No. RE21-01 for the public works aspect of the approved demonstration project.
TIMING CONCERNS
The research unit is currently being manufactured by 374Water and will be ready for shop testing in January 2023, with delivery shortly after.
RAMIFICATIONS OF NOT TAKING ACTION
Not taking action will delay the installation of the research unit currently being manufactured by 374Water.
PRIOR COMMITTEE/BOARD ACTIONS
December 2021 - Approved a Professional Services Agreement to 374Water Systems, Inc. for the Supercritical Water Oxidation Demonstration at Plant No. 1, Project No. RE21-01, to provide goods and services for demonstration of the 374Water AirSCWO Nix6 System, for an amount not to exceed $5,139,000; and approved contingency funds for Project No. RE21-01 for a combined total not to exceed $514,000 (10%).
