FREE service for all Walla Walla County residents!

The Household Hazardous Waste Facility provides citizens of Walla Walla County a way to properly manage their household hazardous waste. Examples of household hazardous waste include paint, pesticides, and motor oil. If you have a question about what the HHW Facility will accept, please refer to the specific lists below or give us a call.

This waste, if improperly disposed of — such as thrown in the trash, poured in storm drains, sewers, or on the ground — could contaminate streams or creeks, expose children and pets to dangerous materials or poisons, and harm the environment.

Contact the manufacturer of your smoke detector for additional information on the safe disposal of this product. Asbestos must be properly bagged as a hazardous material before disposal at Sudbury Landfill. You should contact a professional abatement contractor for assistance in removal and disposal of asbestos containing material.


Proper disposal of medications is also important, but not offered at the HHW facility. Please contact your local law enforcement agency to inquire about sponsored take-back events. Never flush unused medications down the drain or toilet as it can impact the ability of the Wastewater Treatment Plant to properly treat sewage.

Less Toxic Alternatives

Proper management of household hazardous waste begins by eliminating many of those toxic products to begin with.

Non-Residential Moderate Risk Waste Disposal

The HHW facility does not accept materials from businesses (other than eligible lights under the LightRecycle program outlined above). Businesses who qualify as Small Quantity Generators (SQGs) should refer to the Department of Ecology's website for resources to meet their specific moderate risk waste disposal needs.

LightRecycle Offers FreeDisposal of Mercury Containing Lights

A new program designed to collect and properly dispose and recycle mercury containing lights went into effect on Jan. 1, 2015. The Sudbury HHW facility is participating in this program as well as Batteries+Bulbs. Please see the LightRecycle website for program details.

E-Cycle Washington Offers Free Disposal of Select Electronics

Do you have old electronic devices that you'd like to recycle? Remember that Washington State offers free recycling of old televisions, computers, monitors, laptops, e-readers, and portable DVD players.

Properly dispose of your batteries by bringing them to the HHW facility. When certain types of batteries are disposed of in the garbage they can potentially cause a fire in a garbage truck or in the landfill when they are crushed.
