Water Reclamation Facility No. 2 Odor Control and Flow Equalization Project

The contract involves a comprehensive upgrade to the Water Reclamation Facility No. 2, focusing on enhancing flow management and odor control systems. Key tasks include decommissioning and demolishing existing flow equalization ponds and a screw pump station, then designing and constructing new equalization basins at the location of the former pond No. 2. The project also entails replacing the existing pump station with a Vaughn chopper centrifugal pump system, installing a new coarse bubble aeration system to improve wastewater mixing, and implementing an odor control biofilter system. Additionally, aluminum covers will be constructed over the grit chamber, primary clarifiers, and new EQ basins to contain odors, all designed with safe access for inspection and maintenance. The scope extends to sitework improvements such as concrete work, grading, paving, piping, and other site enhancements, along with modifications to existing facilities as needed. The project encompasses all necessary electrical infrastructure, including wiring, conduits, grounding, Variable Frequency Drives (VFDs), and system integration, with coordination for SCADA programming to ensure seamless operation with the City’s control systems. Regulatory compliance, including permits and AQMD approvals, is also a critical component. The contractor will provide startup services, performance testing, and training for City staff to ensure proper operation of the new systems. The project details are outlined in the Bridging Documents provided in Exhibit A, and it is solicited under the NAICS code 238910, with the City of Corona acting as the contracting agency. The response deadline was July 13, 2022, and the project is managed through a formal solicitation process.
