Environmental Spills, Hazardous Waste
The Environmental Control section of the City of Reno, Public Works Department works to keep our environment safe and free of harmful pollutants in our waterways. We also respond to environmental emergencies to oversee cleanup of spills into stormwater or sewer collection systems.
Stormdrains channel runoff water directly back into to the environment and should NEVER be used to pour chemicals, oil, or other contaminants into. To report a spill or possible contamination, please call 775-334-2350.
For disposal of household chemicals or other hazardous waste, please call the District Health Department at 775-328-2436.
