Iowa · Jefferson County
2 businesses are filed under Jefferson County on the Iowa DNR licensed commercial septic tank cleaner roster dated August 19, 2026.
Under Iowa Administrative Code 567 chapter 68, commercial septic tank cleaners must obtain a DNR licence. Every business on this page appears on the dated roster, and its DNR licence number is on the card. The DNR sorts the roster by county itself, so nothing here is inferred — but the county is where the DNR files the licence, not a promised service area.
These businesses are based around FAIRFIELD. The DNR roster publishes a licence number, business name, contact, email, address and phone — more contact detail than most states here — but no expiration date, so no card shows one.
Excavating, plumbing and drainage firms hold this licence too. 1 of 2 here name septic; the rest are flagged so you can confirm household septic tank pumping first.
