Dropping off Your Household Hazardous Waste is as Easy as 1-2-3!

San Mateo County’s Household Hazardous Waste Program is a “full-service” program.

San Mateo County has offered a Household Hazardous Waste (HHW) Program for over 24 years for residents to drop-off a variety of HHW such as cleaning chemicals, batteries, paint, fluorescent lights, propane tanks and more.

The program is free to residents and continues to be a popular way to get rid of unwanted toxic waste.

Next time you use the program – whether it is at our permanent facility in San Mateo or one of our temporary events in Daly City, La Honda, Menlo Park, Pacifica, Portola Valley, or South San Francisco – here are some quick tips to help you help us make the program a success for everyone.

1. Make an appointment. You can do so online at smchealth.org/hhw or by calling (650) 363-4718, select option 3.
2. Gather your waste in a sturdy box. Don’t mix waste and make sure they are in their original containers. Check our website for a list of accepted waste. The limit per appointment is 10 gallons or 50 pounds.
3. Arrive at your designated time. The HHW program is “full-service” so stay in your vehicle while we take the waste directly from your car. Just make sure to place it all in an easily accessible location for staff to reach.

And that’s it!
