Local Water Utilities United for Safe Drinking Water


The symbols under “Disposal Method” suggest the best disposal procedure for each hazardous product listed. The following disposal symbols mean:
Pour down the drain with plenty of water. If you use a septic tank, take special caution. Read the product labels to determine if it will be harmful to your septic tank. If it is, take to the Household Hazardous Waste Program.
Place in the garbage.
Always try to use up or recycle the product first. If this is not possible, take to a Household Hazardous Waste Drop Site, find vendors at the Spokane Waste Directory or call the Recycling Information Hotline at 509-477-6800.
