Counties this site covers
Indiana runs septic permitting through 92 county health departments. The state writes one rule and every county administers it with its own application form, its own fee schedule and its own answer to whether an installer needs a credential. That is why the useful question is never "what does Indiana require" but "what does my county require". These are the counties this site covers today.

What changes from county to county
- The application form and what it asks for.
- The fee, which every county sets for itself.
- Whether an installer needs an IOWPA certificate, a county installer permit, or neither.
- Whether the county requires an operating permit, and on what renewal cycle.
- How the county holds and releases its records.
Each county page carries what that county's own health department publishes: its forms, its lists, its installer requirement and, where the county publishes them, its fees. Where we could not read something, the page says so rather than borrowing the county next door.
