Before the rig arrives

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

After drilling: Completion report (DCP custodian) within 30 days → Local Director 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.
