Confirm parcel allows a private well (vs required public water connection).
Select a licensed well contractor; obtain owner authorization as required.
File permit with Local board of health (PDF/email/mail — WellMap prepares the packet; lawful submitter files).
Do not drill until authorization is issued (or notification accepted, per regime).

After drilling: Well log (ODNR channel) within 30 days → Local board of health

WellMap prepares estimate-backed quote packets and dual-party approvals. It does not issue permits and never auto-submits to government systems. The licensed driller (and/or owner where required by law) is the submitter of record. Verified 2026-07-14.
