Wastewater Treatment Facility Outfall and Diffuser Project

The State Water Resources Control Board is funding the Wastewater Treatment Facility Outfall and Diffuser Project in Yuba City, California, under Project Number 8682-110, with the City of Yuba City serving as the lead agency. The project involves substantial infrastructure upgrades to improve effluent discharge from the wastewater treatment facility, including modifications to existing effluent pumps, installation of a bifurcation station with flow metering to direct flows between the new outfall and existing disposal ponds, and construction of approximately two miles of new pipeline leading to a 250-foot diffuser structure in the Feather River. The diffuser consists of a 36-inch diameter welded steel pipe with sixteen 12-inch risers equipped with discharge ports, designed for controlled effluent dispersion. At the levee crossing, a vacuum-assisted siphon priming system will be installed, comprising a building, valve vault, and trap structure to ensure reliable pipeline operation. Additional project elements include a permanent access ramp along the Feather River West Levee, new electrical connections to the bifurcation station and vacuum building, and acquisition of both permanent and temporary easements across private and public lands to facilitate construction and long-term operation. Environmental compliance is ensured through a Mitigated Negative Declaration under the California Environmental Quality Act, with oversight from both the City of Yuba City and the State Water Board. The procurement is currently in a forecast status, posted on July 16, 2026, with funding approved by the State Water Board on July 15, 2026. No formal solicitation number, contract value, pricing, or detailed performance timeline has been published, indicating the project remains in the planning or pre-solicitation phase. Key contacts include Katherine Willis, Environmental Compliance Manager for the City of Yuba City, and Cedric Irving, Environmental Scientist with the State Water Board. The place of performance is concentrated in Yuba City and the adjacent Feather River corridor, extending into unincorporated Sutter County. While the project scope is well defined in terms of engineering deliverables and environmental compliance, no contract clauses, evaluation factors, packaging requirements, special provisions, or offeror certifications have been specified in the available documentation. The absence of FAR sections, clause references, and formal procurement details suggests this is a preliminary announcement outlining project intent rather than a formal solicitation, with full contracting procedures expected to follow pending final planning and funding confirmation.
