Drinking Water Operator Training and Certification is now accepting exam applications via email. The exam applications have been completely reformatted as a fillable PDF. The applications have changed, so be sure to read the instructions carefully within the application. To apply by email, follow these three steps:

Step 1) Fill out the exam application(s)

Step 2) Complete payment online

Step 3) Submit both the payment receipt and the exam application(s) to EGLE-DWEHD-OTCU-Exams@Michigan.gov

Approval/Denial Letters for the exam are typically sent out about one month before the exam date. If you do not receive an approval/denial letter from OTCU at least two weeks before the exam date, please contact our office.

*You will receive a reply email if it was submitted to the correct email address. Be sure to send it to the correct email address. Refunds will not be given for failed submissions.

Common Issues with Exam Applications

• Typing the email address incorrectly.
• Failing to sign your application(s). If you do not sign your application, your application will be denied.
• Leaving the job duties box and percentage blank.
• Missing a supervisor signature on job experience. If you are required to submit experience it must signed by your supervisor.
• Applications submitted late will be automatically denied and no refund will be given.

Location preference for examination is on a first come, first serve basis, therefore, emailing the application will get it to us much faster.

Here are the links to the new Distribution, Limited Treatment, Complete Treatment, and Level 5 exam applications.
