Household Hazardous Waste

The District reminds residents that many products found in our homes are potentially hazardous substances. They can poison, corrode, explode, or ignite when stored or handled improperly. When indiscriminately discarded along with household trash these substances can threaten human and environmental health.

For proper disposal of household hazardous waste, Contra Costa County has established a special Waste Collection Facility that gives local residents and small businesses an environmentally sound alternative. All communities within the Moraga-Orinda Fire District service area are eligible to use this facility. Residents may drop off household hazardous waste at no charge. Small businesses pay a small fee to dispose of their hazardous waste.


Bring unwanted medications to:

  • Moraga Police Department (329 Rheem Blvd, Moraga)
  • Orinda Police Department (22 Orinda Way, Orinda)

Collection sites are open Monday to Friday from 8 AM to 5 PM

To ensure privacy, transfer prescription pills to a sealable plastic bag before depositing. To prevent spills, leave liquids in original bottles (cross out personal information) and seal within a plastic bag. Please do not flush your drugs.

For additional Contra Costa County collection sites outside of Moraga or Orinda, call (800) 646-1431 or visit
