Cass County septic pumping companies
6 businesses with a current MPCA Maintainer licence give a Cass County business address. Retrieved September 5, 2026.
What the Maintainer licence means
Minnesota licenses subsurface sewage treatment system businesses by designation, and Maintainer is the one that matters here — MPCA tells homeowners they must employ a state-licensed maintenance business to pump out solids from a septic tank. Installer, Designer, Inspector and Service Provider are separate designations that can sit on the same licence; 2 of the 6 businesses here are licensed installers as well, which the card shows.
Every licence on this page had status Current when this snapshot was taken on September 5, 2026, and each card carries the licence number and its own expiry date so you can check both. The county is the licensed business address, not a promised service area.
