Steps
Confirm project scope: Iowa requires a private well construction permit for closed-loop systems 20 feet or greater in depth, and for all open-loop systems
Obtain the private well construction permit (issued by the county health department in most counties) before boring
Ensure an Iowa DNR Certified Well Contractor is on-site throughout borehole drilling, loop pipe fusion, and grouting
Complete continuing education covering geothermal/loop-specific topics for the current two-year certification cycle
File required construction documentation with DNR or the delegated county authority at completion
Known gotchas
Iowa uses a single Certified Well Contractor credential covering water wells, pump work, and geothermal boreholes rather than a separate geothermal-only license; other states structure this differently with distinct geothermal endorsements, so don't assume Iowa's model applies elsewhere
The permit issuer is typically the county health department, not DNR directly, for private wells
Loop pipe fusion and grouting must occur under the certified contractor's on-site supervision, not be subcontracted without that oversight
