Pollution Prevention Programs


Pollution Prevention Programs
Empowering our customers as environmental stewards

We’re committed to educating our customers about how they can help protect our region and become proactive environmental stewards. We work hard to protect the health of our region and the natural world around us.

The level of treatment the wastewater receives during our treatment process is dictated by a discharge permit issued by the Central Valley Regional Water Quality Control Board.

For some pollutants that wind up in our wastewater – either directly through disposal or indirectly through stormwater runoff – the most effective approach to keeping them out of our waterways is preventing them from entering the sewer system in the first place. We call this “source control.”

To educate our customers about how they can help control pollutants of concern at the source, we’ve developed outreach programs that encourage sustainable habits that keep our environment healthy.


Proper disposal of your unused meds is easy!
Find out where you can take your unused medications for safe disposal

To prevent misuse and keep medications from entering our waterways, please dispose of unused prescription and over-the-counter medications responsibly. Flushing unused or expired medications down the sink or toilet can pollute the environment.
