Composted material or ash from a waterless toilet cannot be disposed of on-site. Incomplete composting can leave harmful bacteria or pathogens in the waste, making it unsafe for people and the environment.
Under Sonoma County’s program:
All waste must be hauled offsite by a licensed waste hauler for proper disposal.
Ash from incinerator toilets must also be disposed of safely and cannot be buried or spread on the property.
The property owner is responsible for ensuring proper operation and maintenance of the system.
All waterless toilets must be enrolled in the County’s Operational Permit (OPR) Program for ongoing monitoring and recordkeeping.
