Nebraska · Knox County
4 businesses hold a DWEE Pumper certification and a Knox County business address, checked September 6, 2026.
Nebraska certifies onsite wastewater professionals as people, and lists a business because it employs at least one of them. The certification that allows pumping your tank is Pumper — not Pump Installation, which is water-well pump work and a different credential that merely shares a word. Every business on this page holds Pumper, and 4 of 4 are certified to install systems too. Each card lists the certifications behind the business.
DWEE publishes the county itself, so nothing here is inferred from a town or a ZIP — but it is the county of the business address, not a promised service area. A Nebraska certification is valid statewide, so a business in the next county may well cover you.
These businesses are based around Creighton, Crofton, Verdigre. DWEE publishes a business name, address, county, phone and the certifications behind the business, but no certification expiry date, so no card shows one.
Plumbing, excavation and portable-toilet firms hold this certification too. 0 of 4 here name septic; the rest are flagged so you can confirm household septic tank pumping first.
