Household Hazardous Waste Collection Event in Rainier May 20

Your household hazardous waste must be in your vehicle's bed, trunk, or hatchback - not the passenger compartment. Unloading may take a few extra minutes as extra safety measures will be in place. Please be patient, and please remain in your car.

The City of Rainier will host a county-sponsored Household Hazardous Waste (HHW) Collection Event on Saturday, May 20, 2023, from 8 a.m. until noon. The HHW Event will be held at 690 West A Street, next to the Rainier Sewage Treatment Plant. You can drop off various toxic and unsafe household materials at no cost.

Trained household hazardous waste technicians will unload materials from your vehicle. Items must be in containers of less than five (5) gallons and should be secured safely during transport.

Examples of acceptable items are:

  • fireworks and flares 
  • gas / diesel / fuels / motor oil / antifreeze
  • lawn and garden chemicals 
  • herbicides and pesticides 
  • pool and spa chemicals 
  • light ballasts—must be removed from light fixtures
  • fluorescent tubes 
  • art and hobby chemicals 
  • solvents and thinners 
  • items containing mercury 
  • propane and compressed gas cylinders 
  • batteries – all types and applications

  • paint and paint products (latex and acrylic paint, oil-based paint, enamel, stains, lacquers, shellacs, varnishes, primers, etc.)
