North Dakota · Dunn County
5 businesses are based in Dunn County on the DEQ sanitary pumper list dated July 23, 2026.
DEQ has not replaced the sanitary pumper PDF since that date. Businesses close, change hands and let permits lapse in that time, so treat this as a starting list rather than a current register. Confirm the sanitary pumper permit is still current before you book.
North Dakota requires a DEQ sanitary pumper permit to pump a septic tank and haul the waste. Class I and Class II are both septic system servicers. 4 of 5 here are Class I. DEQ publishes the business county itself, not a promised service area; a sanitary pumper permit is valid statewide.
These businesses give addresses around Dickinson, Gladstone, Halliday, Killdeer. DEQ publishes a permit number, business name, permittee, address, county, phone, class and an expiry date, and the list itself is dated July 23, 2026.
Portable-toilet and excavation firms hold this permit too. 1 of 5 here name septic or cesspool; the rest are flagged so you can confirm household septic tank pumping first.
