This service is provided by the Tri-County Health Department
Many common products found in your home such as oil-based paint, mercury, gasoline, degreasers, cleaning compounds, and garden chemicals may be hazardous and they should be used and disposed of carefully. These community events help prevent pollution and protect the people handling your garbage.
This service is open to all residents of Douglas County. Please bring a utility bill, phone bill, or driver’s license to verify your address. (A contribution of $25 is requested to help offset the high cost of hazardous waste disposal.)

Latex paint Waste Disposal and Reduction Tips
- Water-based latex paint should be disposed of in regular household garbage IF it is completely dried out.
- Mixing the paint with kitty litter, dirt, or concrete-mix will help speed the drying process.
- Dry cans of paint, with lids removed, can be discarded in the trash.
- Buy only what you need by carefully estimating the square footage of the surfaces to be painted. One gallon of paint will cover about 350 square feet.
- Ask your local paint store if they provide small (1-2 ounce) samples for color testing before investing in gallons of paint.
- Give any leftover paint to a neighbor in need.
