What does the examination for apprentice sewage treatment collection operator consist of?
This depends on your location. In the US, for example, each state has certain operator certification processes that must be followed. Class A classification tends to require 1040 hours of operating experience. This means you’ve got to become an apprentice before you can actually take the certification exam.
If your local standards require an exam to become an apprentice in the first place, there are plenty of third-party educational experiences that can help you find what you need. Look for courses at community colleges for an inexpensive initial certification. You can also talk with your local operators to see what local requirements happen to be.
I’d personally recommend doing both. Enrolling in an educational program can help you get your knowledge base a solid foundation and getting to know local operators can start building your professional network. Check local requirements as well.
As for the exam itself, you’re going to be asked questions about what it is that a sewage treatment collection operator does over the course of their job duties.
