Vanderburgh County septic permits
Vanderburgh County environmental health specialists do more of the work in-house than most: they conduct a site evaluation including a topographic characterization and review the soil profile analysis for each new construction, alongside the homeowner, the installer and the soil scientist.
Who issues a septic permit in Vanderburgh County?
The Vanderburgh County Health Department. Under the state rule the owner or the owner's agent has to obtain a written construction permit signed by the health officer before the work starts, and in Indiana that health officer is the county's, not the state's.

Who can legally do the work here?
Indiana has no state septic installer license, so the answer is set by this county. Many Indiana counties require an IOWPA certificate, and some run their own installer permit and exam. Check with the Vanderburgh County Health Department before you sign anything, because the requirement is different one county over.

What comes before the application?
Before any construction permit is issued, and before a soil absorption system is replaced or altered, an on-site evaluation including a description of the soil profile has to be conducted. The soil is described by a soil scientist using NRCS guidelines, and the profile is recorded to a depth of five feet or until a layer is reached that cannot be read.
So the first call is usually a soil scientist, not a contractor with a machine. See the soil evaluation and the application sequence.
