Dubuque County septic pumping companies

8 businesses are filed under Dubuque County on the Iowa DNR licensed commercial septic tank cleaner roster dated August 19, 2026.

What the licence means

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.

3 businesses on this page are marked by the DNR as based outside Iowa while licensed in Iowa and filed under this county; the cards say so.
