Applying for an Indiana septic permit

1. An on-site soil evaluation, with the profile described by a soil scientist.
2. A system design that suits what the soil evaluation found.
3. The county application, with the property information, the soil evaluation and the design.
4. The county's written decision, issued or denied by the health officer.
5. Construction by the installer your county allows to do the work.
6. The county's inspection before the system is covered.

The rule puts the duty on the owner or the owner's agent to obtain the permit. In practice a contractor often applies as your agent, which is fine and normal, but the obligation is still attached to the property owner. Ask who is applying before the paperwork goes in.

• The property information the county asks for on its own form, including the parcel.
• The soil evaluation report.
• The system design, often as a scale drawing.
• The number of bedrooms, which sizes the system.
• The county's fee, which every county sets for itself.

Your county health department's own page is the authority on the form and the fee. This page describes the shape of the process, not one county's paperwork.

That depends on the county, the season and how busy the soil scientists are. What we will not print is a statewide number of days, because the counties do not share one. Ask your county when you file, and plan the build around the answer rather than around a number from the internet.

A denial is written, and the rule provides for appeals, including an option for the parties to use the state's Administrative Orders and Procedures Act procedures. Most denials in practice are a design the soil will not support, which sends you back to the design rather than to a lawyer.
