Household Hazardous Waste Collection Service

The San Antonio River Authority, along with local partners, hosts six (6) free Household Hazardous Waste Collection Events within Wilson, Karnes, and Goliad counties. These semi-annual events are held in the spring and fall. County residents may stop by to drop off unwanted household hazardous waste, tires, paint, used motor oil & filters, cleaning products, pesticides, computers, small electronics, and pharmaceuticals.

The River Authority hosts these household hazardous waste collection events with the hope that it will lead to a reduction in waste that enters our creeks and rivers. These are free events and are first come, first serve due to availability. Visit the Events tab to see upcoming County Wide Collection Events in your area! 

No businesses please. Residents of Wilson, Karnes, or Goliad County respectively, proof of address is required. Collection will close at the discretion of the sponsors.
