Department of Environmental Quality–listed septage pumper based in Marlow. Last checked 2026-08-17.
Call to confirm they still take your job and cover your address.
Double L Oilfield and Septic appears here because the name and phone match a current Oklahoma Department of Environmental Quality septage pumper and transporter row. The roster mailing city is Marlow, Oklahoma. That is a starting point for a call about septic pumping — not a rating, endorsement, or coverage map.
Ask whether they still take the exact job at your address, what they charge, and when they can come. A Marlow mailing city does not mean they cover every street in Marlow or nearby Oklahoma towns. If this page is missing a website, email, or street address, we did not have a roster fact for it and we do not invent those fields.
Ask whether they pump conventional tanks, aerobic trash tanks, or both at your address.
Keep notes on the last pump-out, tank size if you know it, and whether the yard is wet. Then compare this record with other Oklahoma companies on the directory before you schedule.
