Composting Toilets       Further information needed   Before installing a composting toilet, consult with Seattle Public Utilities as well as the Seattle and King County Public Health Department (or your respective localities) to investigate building and health codes and how to secure a permit within the city.  Homeowners and contractors should work closely with the Public Health Department to come up with an ongoing pathogen management plan.  Due to the multi-floor components of the system, it is advised to consult an architect or building inspector to determine if your house can support a composting toilet.  Consult with a composting toilet manufacturer to calculate waste loads and expected compost output.
