DEQ-listed aerobic spray company in Hugo. Confirm aerobic work when you call. 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.
Diamond J Construction 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 Hugo, 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 Hugo mailing city does not mean they cover every street in Hugo 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.
