Placer County moves forward on phase 1 of Highway 49 wastewater capacity project

Location mapPlacer County is moving forward with the first phase of an estimated $18 million wastewater pipeline extension designed to accommodate future growth in the Auburn area.

The project will extend an existing sewer line along state Route 49 from near Edgewood Road to the Sewer Maintenance District 1 Regional Pump Station on Joeger Road. 

The Placer County Board of Supervisors took action on Nov. 27 to adopt environmental documents, approve plans and specifications for the pipeline extension and authorize the Department of Public Works to solicit construction bids for the first phase of the project, which will total an estimated $8.26 million.  

Phase one of the project will be funded through $500,000 of Sewer Maintenance District 1 capacity reserves, $3.76 million from a Sacramento Area Council of Governments Green Means Go grant, and $4 million of the county’s American Rescue Plan Act allocation funds. 

“I want to thank staff for finding the funding for this without putting the burden on ratepayers of (Sewer Maintenance District 1). This project is very necessary for growth in the Auburn area,” said Board Chair and District 3 Supervisor Jim Holmes. 

The existing wastewater gravity trunkline was constructed in 1960 as part of the formation of Sewer Maintenance District 1. The approved project includes a retrofit solution to divert flow from the existing gravity system to increase flow capacity to support existing use and planned growth in the Auburn area. The project extension is consistent with the Placer County General Plan and  will be approximately 22,400 linear feet with the pipeline varying between 24-and-30 inches in diameter. 

Work is expected to begin in spring of 2024.
