What Oklahoma requires
Any business that pumps, transports, or disposes of septage in Oklahoma must hold an annual license from the Department of Environmental Quality. The public Active Septage Pumpers and Transporters list shows the license number, company, phone, address, and county. DEQ currently publishes a roster dated November 5, 2025. Appearance on that file is not proof that the license was renewed for the current year.
Verification steps
- Ask the company for its full business name and DEQ septage license number.
- Open the official Oklahoma DEQ septage pumpers list.
- Match the license number, company, phone, and address.
- Confirm the firm still appears on the official DEQ list on the day you book. The public CSV may lag annual renewals.
County does not mean service area
The county on the DEQ list belongs to the licensed business location. It does not guarantee that the company serves every property in that county—or only that county. Ask about coverage and travel charges for your exact address.
How SepticByCounty filters the state list
The DEQ roster includes septic companies plus portable-restroom, construction, plumbing, sanitation, marina, and oilfield-pumping businesses that also hold septage licenses. Our homeowner shortlist only publishes roster records whose company name explicitly says septic or septage. We do not turn a pump-only or ambiguous company name into a septic claim, and we do not treat the November 5, 2025 Active filename as current renewal status.
