CITY OF GREENFIELD WASTEWATER TREATMENT PLANT UPGRADE PROJECT

The City of Greenfield Wastewater Treatment Plant Upgrade Project involves the construction of an upgraded 2.0 million gallons per day facility located at 41901 Walnut Avenue, Greenfield, California. The project is scheduled for completion within 915 calendar days and is divided into four distinct phases: site preparation including soil stabilization and bypass piping; construction of the plant featuring a Membrane Bioreactor treatment plant, UV disinfection, and SCADA systems; decommissioning and demolition of existing facilities; and the completion of finish facilities including the Walnut Avenue extension. A critical requirement is that the existing plant must remain operational during the first two phases while maintaining continuous compliance with General Order/NOA standards. This solicitation is open to various small and disadvantaged business categories, including VOSB, SDVOSB, WOSB, and SDB. A significant local hiring mandate requires that 50 percent of the total construction workforce be residents of Monterey, San Benito, or Santa Cruz counties. Bids are due by October 28, 2026, at 2:00 PM, following a mandatory pre-bid meeting held on October 5, 2026. Subcontractors must agree to the Overaa standard agreement, provide a 100 percent faithful performance and labor bond if requested, and utilize the Textura electronic invoicing system, with associated service fees borne by the subcontractor.
