Steven says: "Don't flush 'em. Drop them off safely on Prescription Take Back Day!"

When medications are flushed, they can end up polluting the environment. Find a safe drop‑off location near you at MedTakeBackCalifornia.org.

Say it with us: wipes clog pipes.

Yes, even the ones labeled "flushable." Keep it simple by only flushing the 3 P's: p*e, p**p, and toilet paper. Everything else belongs in the trash.

Behind every drop of clean water is a team that makes it possible 💧

On , we’re reminded why the work we do matters. Each day, we go beyond treating wastewater by recycling every drop we can. This means 100% of our reclaimable flows are sent to the Groundwater Replenishment System, providing clean, reliable water for one million people in Orange County.

Miles of sewer pipelines. Hundreds of manholes. A whole lot of improvements!

A little construction now means a more reliable system for our community later.
