Protective Equipment Policy
PSI has adjusted policy on the use of facemasks and gloves based on recommendations of the CDC.
Once you have obtained a PASSING grade on the computer-based exam, you must download the computer-based exam license application form and submit it to NEIWPCC with (a copy of) your PASSING exam results, copy of your driver’s license (or other ID) and license fee. NEIWPCC will then issue your new Wastewater Operator credentials.
There is no need to contact NEIWPCC for non-passing exam results. You may schedule and re-take another computer-based exam at any time.
After you pass the exam and get your wastewater credentials from the state, it is time to get a position. Wastewater plants post job openings on the Massachusetts Water Environment Association’s website. Their jobs hotline can be found here. The site is updated regularly.
For questions and information related to Massachusetts certification please view our short webinar, Becoming a Certified Wastewater Operator in Massachusetts. The slides in this webinar may be viewed separately here.
