Water & Wastewater Program
Incinerating or Composting Toilets will not require a "Permit to Construct" as long as these systems are completely self contained (i.e. -no systematic continuous discharge allowed). The occasional removal of solids (compost or ashes) is allowed so long as they are properly disposed of or beneficially reused.
However, the owner of an allowed permitted composting or incinerating toilet needs to be aware of the following potential future problems. If in the future the composting or incinerating toilet system fails or is abandoned for any reason, the owner would need a fall-back waste disposal plan. This could be either a conventional septic system with a leachfield, a non-conventional treatment system, or a holding tank. Any of these options would require a permit to construct and have to be designed and constructed to the current applicable standards.
Before proceeding with installing either a composting or incinerating toilet the owner/applicant should consider if they would have the suitable land area for an alternative system. Otherwise, the property could become less valuable and much less useful after the composting or incinerating toilet fails and it is not possible to design and construct a permitable replacement system.
