DEQ-listed aerobic spray service in Oklahoma City. Last checked 2026-08-15.
Important: A DEQ roster match does not prove current availability, every service tag, or coverage for every address. Confirm those details with the company.
Foster Septic Tank Cleaning appears here because the name and phone match a current Oklahoma Department of Environmental Quality certified installer row with an aerobic spray flag. The roster mailing city is Oklahoma City, Oklahoma. That is a starting point for a call about aerobic septic installation, repair, maintenance, pumping, or inspection — 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 Oklahoma City mailing city does not mean they cover every street in Oklahoma City 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.
Keep notes on alarms, last pumping, and whether the installer two-year maintenance window is still open. Then compare this record with other Oklahoma companies on the directory before you schedule.
