Wastewater Treatment Facility

The City of Yuba City’s Wastewater Treatment Facility resides on 35 acres at the south end of town.  Originally built in 1975, the facility underwent an expansion in 2003 to treat an average of 10.5 million gallons per day (MGDs).  Yuba City’s current average daily flow is about 6.5 MGDs.  It is a Class IV Wastewater Treatment Facility with a pure oxygen activated sludge process designed to handle high and variable biochemical oxygen demand (BOD) loads from local food processing facilities, commercial facilities and residential areas.  To help with efficiency, the facility will undergo a large improvement and upgrades project starting in 2019.      

Our Mission

Commonly Asked Questions 

Are flushable wipes flushable?

Please don’t, flushable wipes are not flushable!  Put trash in the trash can and only flush toilet paper. Think before you flush! 

The packaging may state that these wipes are flushable, often times they are not.  They do not break down like toilet paper causing havoc on your septic or sewer system.  This can potentially cause major backups and clogs within the sewer lines.  When in doubt, just throw them out!  Watch this consumer reports video on flushable wipes.

Where does "it" go?

There are 17 lift stations throughout the City that feeds the wastewater to the Wastewater Treatment Facility for treatment.  Check out the plant operations page and the Wastewater Treatment Facility video for detailed information on the process!
