Read the date before you use these pages
The Wisconsin DNR publishes this list as a report that stamps its own run date, and that date is June 30, 2023 — the DNR has not re-run it since. Businesses close, change hands and let licences lapse in that time, so this is a starting list, not a current register. The DNR asks anyone who needs an up-to-date copy to email [email protected]. Every page here shows the DNR's date rather than implying the list is current.
How this directory is built
A Wisconsin septage hauling business licence is what allows a company to pump and haul septage, and the DNR names an operator in charge for each one — the certified person answerable for the work. Both the licence number and that person appear on every card.
The DNR already groups the report by county, so no geography is inferred here. Of 319 records on the report, 306 are filed under one of Wisconsin's 72 counties and 13 are filed under “Unknown”, which we do not place on a county page. We also hold 23 clearly portable-toilet, restroom, outhouse, or grease-first names that do not say septic or septage, leaving 283 published listings. 6 published businesses are filed under a Wisconsin county while mailing from another state; their cards say so.
After the clear specialty-name exclusion, 142 of the 283 published businesses name septic in their business name. The rest carry a note asking you to confirm household work first. The report publishes no expiration date, so no card shows one. 3 businesses have no phone on the report at all.
