Bid Title: RFP Arcata Wastewater Treatment Facility Improvements Project
Category: Requests for Proposals
Status: Closed


The City of Arcata is seeking an experienced engineering and planning consultant team to further the Arcata Wastewater Treatment Facility Improvements Project.  The selected consultant will perform a series of tasks including preliminary design, final engineered designs, cost estimates, fee analysis, as well as permit and bidding support.  The project construction will be phased. 

Background: The City of Arcata Wastewater Treatment Facility (WWTF) discharges treated wastewater to Humboldt Bay. Discharges are regulated by the North Coast Regional Water Quality Control Board (RWQCB) through application of National Pollutant Discharge Elimination System (NPDES) permit.  The current NPDES permit requires the City to upgrade the WWTF, including implementation of ultraviolet (UV) disinfection, and routing discharge flows up to 5.9 million gallons per day (mgd) to the City’s new brackish marsh (outfall 003). The City also intends to upgrade, improve, or replace elements of the existing headworks facility and primary clarifier, and upgrade the existing oxidation ponds, treatment wetlands, and enhancement wetlands of the Arcata Marsh Wildlife Sanctuary (AMWS). In addition, the City intends to construct one, and possibly two, parallel flow oxidation ditches and secondary clarifiers to improve treatment to meet current and expected future discharge requirements.
The intent of this project is to implement WWTF improvements identified in the recently completed City of Arcata Facility Plan (Plan) (2017), and the treatment Alternative 4-1 (Alt 4-1) approved by the Arcata City Council in April 2017.
