NEIWPCC will then issue your new Wastewater Operator credentials.
If you did NOT pass the exam please schedule and re-take another computer-based exam at any time.
Step 4: Find a Position
After you pass the exam and get your wastewater credentials from the state, it is time to find a position! Wastewater plants post job openings on the Massachusetts Water Environment Association’s website.
