Keep these documents together
- Issued permit
- Site plot plan and materials
- County as-built form
- County installation guidelines and pre-cover checklist
Use the permit for the approved system, flow, depth, setbacks and use description. A checklist or website cannot approve a deviation. The application describes a commercial/ag-exempt bathroom use for up to three employees, no showers or food preparation; it does not establish approval for other building uses.
Inspection before final cover
Polk County provides pre-cover inspections. Its published guidance calls for a tank watertightness test and an as-built drawing. Resolve the supplier’s tank support/backfill instructions and the county’s required visibility before adding water. Keep the drainfield available until cover is authorized. The project sequence is on the Septic page.
Keep findings, corrections and completion documentation with the project record. Photos document visible work; they are not an inspection certificate.
