Household Hazardous Waste


Grant County Solid Waste offers Household Hazardous Waste Collection events two or three times a year. These events are held on Saturdays in the spring and fall and are for household-generated waste only. Most events are held in Moses Lake and Ephrata. Because funding for these events is provided through a grant from the Department of Ecology and from Grant County Solid Waste tipping fees, there is no additional cost for residents to participate. Residents who bring items that are not accepted at an event will be assisted in finding other disposal options.

For everyone’s safety, please:

  • Don’t mix products
  • Keep products in original containers. Containers will not be returned for everyone's safety.
  • Label products not in original containers. Containers will not be returned for everyone's safety.
  • Secure products so they won’t leak.
  • Store products away from the passenger compartment of your vehicle and keep them separate from items you wish to retain.
  • Stay in your vehicle during unloading.
