Underground septic tanks

This entry only applies to septic tanks, not any other form of underground tanks. Septic tanks must be emptied before disposal.

Note, if you need to dispose of an underground storage tank that previously held a hazardous material (e.g., Used Motor Oil or gasoline), please contact the Certified Unified Program Agencies (CUPA) for your area regarding permits, forms, and fees. Visit PermitSonoma Underground Storage Tanks (UST) for more information.
