Influent Pump Station Project


The Sewerage Commission - Oroville Region (SC-OR) worked with Jacobs Engineering (formerly CH2M Hill) to design a new influent pump station for the wastewater treatment plant in Oroville.  The new pump station has a designed 15 million gallons-per-day (MGD) pumping capactity, and will include new valves, diversion boxes, flow meter, and Supervisory Control and Data Acquisition (SCADA) control center. 

SC-OR received partial funding from the Water Quality, Supply, and Infrastructure Improvement Act of 2014 for the construction of this project in the amount of $3,776,154.00. Funding was made possible through an agreement with The California State Department of Water Resorces and Butte County Department of Water and Resource Conservation. 

On June 15, 2021, SC-OR, along with Jacobs Engineering, held a public bid opening for the influent pump station project.  SC-OR received three bids, and ultimately Gateway Pacific Contractors, Inc. was awarded the project with the low bid of $7,171,451..00.
