Who Needs This Bond?
DEQ certified septic tank installers — defined as anyone who installs 10 or more on-site sewage facilities per year. Two routing points: a non-certified individual may install just one on-site sewage system per calendar year (subject to DEQ inspection) without certification or this bond; and installers working solely for a federally recognized tribe or government entity may be exempt from the bond (confirm with DEQ).
Who May Not Need This Bond
Not everyone has to post this bond — you may not need it at all. In plain terms:
You may not need certification or this bond if you install only one on-site sewage system in a calendar year — a non-certified individual is allowed one install per year, though DEQ must inspect it. Anyone installing 10 or more systems per year must be certified and bonded. Installers working solely for a federally recognized tribe or government entity may also be exempt from the bond (confirm with DEQ).
Why Oklahoma Requires This Bond
Oklahoma requires certified septic tank installers to file a $75,000 surety bond with the Department of Environmental Quality as a condition of certification. As of November 1, 2025, the required amount increased from $10,000 to $75,000 under Senate Bill 111 — a significant change for the trade. The bond is filed in the installer's own name, with DEQ named as obligee, and it must stay in force for as long as the installer holds certification. It guarantees that the installer will build on-site sewage systems in compliance with DEQ's standards under Oklahoma Administrative Code 252:641.
The bond protects the public and the environment, not the installer. On-site sewage systems that are installed improperly can contaminate groundwater and create public health hazards, so if a certified installer does defective work, walks off a job, or refuses to correct a violation flagged by DEQ, the state can file a claim against the bond to recover the cost of repairs or remediation — up to the $75,000 penal sum. The installer must then reimburse the surety in full. The larger bond amount reflects how expensive it can be to fix a failed septic system after the fact.
The $75,000 bond amount is the coverage guaranteed to Oklahoma Department of Environmental Quality (DEQ) — it is not a cost to you. What you pay is the premium, the flat From $375/yr.
