Odor Control Scrubber GAC Media Replacement Project

The Odor Control Scrubber GAC Media Replacement Project, issued by the Procurement Department of Rancho California Water District under RFB 255-2026, requires a contractor to provide all labor, equipment, and materials to replace granular activated carbon GAC media in twelve Odor Reduction Units ORUs. This includes ten units at the Southern Regional Water Reclamation Facility SRWRF and two at wastewater lift stations. The scope of work encompasses the removal and disposal of spent media, cleaning of vessel interiors and support screens, comprehensive inspections, installation of new media, and functional startup testing to verify blower operation and airflow. All activities must be coordinated to maintain continuous facility operations and ensure compliance with South Coast Air Quality Management District SCAQMD permit requirements. Bids must be submitted via PlanetBids by September 17, 2026, and must include a lump sum price for each ORU. Qualified contractors must demonstrate experience with municipal wastewater odor control systems and provide references for three comparable projects completed within the last five years. The contract requires a bid bond of at least 10 percent of the total bid price, with the successful bidder providing performance and payment bonds for 100 percent of the contract value. Key deliverables include pre-construction submittals such as product data sheets and safety data sheets, as well as a final ORU Inspection Report prior to project acceptance. Replacement media must be delivered in original manufacturer packaging and stored indoors to prevent contamination.
