Michigan · Washtenaw County
5 businesses hold a septage waste servicing licence filed under Washtenaw County on the Michigan EGLE hauler directory refreshed September 4, 2026.
MCL 324.11702 requires two EGLE licences before anyone may pump your tank: a septage waste servicing licence for the business and a septage waste vehicle licence for the truck that shows up. Every business here holds both — the licence number is on the card, and so is the number of sealed tank vehicles EGLE has licensed to it. Between them these licences cover 12 licensed vehicles.
The county is where EGLE files the licence, not a promised service area: an EGLE licence authorises work anywhere in Michigan, so firms filed in neighbouring counties may serve your address too, and a firm filed here may not. Before EGLE issues either licence, a certified city, county or district health department inspects the trucks, the sites and the servicing methods.
These businesses are based around Ann Arbor, Chelsea, Northville, Saint Joseph, Willis. EGLE publishes a licence number, business name, address, phone and the licensed vehicles behind each licence, but no expiration date on the directory, so no card shows one. Michigan septage licences run on a five-year cycle with fees due every year.
Portable-restroom, excavating and drain firms hold this licence too. 0 of 5 here name septic or septage; the rest are flagged so you can confirm household septic tank pumping first.
Michigan is unusual in putting the credential on the vehicle itself. MCL 324.11707 requires every licensed septage truck to display, on both sides in letters at least two inches high, the words “licensed septage hauler”, its EGLE vehicle licence number, and an EGLE-issued seal showing the year. An unmarked tanker in your driveway is the single clearest red flag there is.
