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.

Business Generated Hazardous Waste Assistance

Grant County Solid Waste assists small quantity generators (SQG) in finding disposal options for dangerous waste. To learn more about SQGs, please visit the Department of Ecology.

An SQG may dispose of hazardous waste the day before a Household Hazardous Waste Collection event or hire a company to pick it up at the business location. Both options usually require a fee. For more information about disposal options, please contact the Solid Waste Programs Coordinator. Please allow a few weeks to get signed up for a collection event. An SQG may also use PaintCare to dispose of architectural paint.
