Operator certification levels are governed by general statutes in each state. These general statutes specify what is required to be eligible for a specific certification. Most certifications follow a similar path, so we will illustrate one example in this article.
Biological Water Pollution Control System Operator Certification.
There are 4 levels of operator certification, from Grade I through IV. Grade I is the entry level certification that does not require wastewater experience. Grade IV requires years of experience and education to obtain. These grades are based in conjunction with plant level ratings. Plants are rated based on design flow and type of processes involved.
