SB 111 Oklahoma Senate · 2026 Regular Session

Contractors; decreasing number of sewage disposal system installations for certain certification. Effective date.

SB 111 requires contractors installing more than 10 individual sewage disposal systems (for single homes or duplexes) annually to obtain certification from Oklahoma's Department of Environmental Quality. It updates rules for soil testing and system design, mandating certification for all such work and establishing annual fees, penalty procedures, and revocation processes. The bill directly affects residential sewage system installers, ensuring they meet state certification standards. It maintains the existing threshold of 10 systems per year for certification requirements but clarifies and modernizes the regulatory framework. The law became effective November 1, 2025.
