To be a DEQ certified installer of on-site sewage systems in Oklahoma, you must file a surety bond naming you as principal and DEQ as obligee. Our application shows a $10,000 amount, but DEQ raised the installer bond effective November 1, 2025 — so confirm your current figure. We issue whatever DEQ requires at a flat 3%.
















Certification bonds are simple. Here's the entire process:
Check whether DEQ wants $10,000 or the $75,000 that took effect November 1, 2025, then enter your details and an effective date. No financials, no credit section.
Bonds like this are among the thousands of types that issue right after purchase. At most, 1–2 business days.
Your executed bond arrives by email, naming you as principal and DEQ as obligee, ready to submit. Wet-ink original mailed on request.
Bond amount × 3% = your premium, $275 minimum. Confirm whether DEQ wants $10,000 or $75,000 and the premium follows.
Oklahoma's Department of Environmental Quality certifies the installers who build and repair individual and small public on-site sewage treatment systems — septic tanks and their soil treatment fields. Certification is conditioned on a surety bond naming you as principal and DEQ as obligee, under the DEQ on-site sewage rules (OAC 252:641).
The bond backs your compliance with the certification regulations, giving the public a source of compensation if an installer's failure to follow the rules causes financial harm. It is not insurance for you — if the surety pays a claim, you repay the surety.
The amount changed. DEQ raised the certified installer bond to $75,000 effective November 1, 2025. Our scraped application still reflects an earlier $10,000 figure, so we list this bond honestly rather than imply the old number is still correct — confirm your current requirement with DEQ and we issue exactly that.
These are the actual issuing fields — no credit check section. Confirm your amount with DEQ first, since the requirement changed in 2025.
